Later, the review of the species by McDowell (1979) revealed considerable geographic variation suggestive of taxonomic differentiation, although the picture he obtained was considered inconclusive and no subspecies were recognized. Our own studies of geographic variation indicate that the species as currently recognized does indeed constitute a complex of several taxa. Resolution of nomenclature for those taxa hinges upon fi xation of the earliest name applied in the complex, Schneider’s Boa carinata. In the absence of type locality, application of Schneider’s name would hinge solely on characteristics of the onomatophore (name bearer; Simpson, 1940). Schneider based his name on eight syntypes, without designation of any one as the onomatophore. As summarized by McDowell (1979), Schneider cited one specimen in the Ludwigian collection, two in the Lampian collection, fi ve in the Museum of the Duke of Brunswick, and one in the Göttingen Museum. The latter was most fully described by Schneider, and was designated by McDowell as the lectotype, which he thought was “probably lost.” Nevertheless, on the basis of the number of ventrals and caudals, and other data in the original description, McDowell concluded that the type locality probably was in the “South Moluccas.” Inasmuch as greater certainty of the geographic origin and identity of the name-bearer for Candoia carinata, as the species is now known, appears desirable (in view of the several taxa that now seem to be involved), a concerted effort to determine the fate of the lectotype revealed that the specimen does indeed exist, and is now No. 35503 in the Zoologisches Forschungsinstitut und ABSTRACT: The lectotype of Boa carinata Schneider, 1801, has been rediscovered and is now ZMFK 35503, having been transferred in 1977 from the Göttingen Museum, its original location. Its type locality has not been reported previously, but is indicated as “Amboina” on a label with the lectotype. The specimen is redescribed and fi gured, and conforms with expectations for material from the vicinity of the type locality. A brief history of Schneider and of the syntypes of Boa carinata, now Candoia carinata, is reviewed.","PeriodicalId":173367,"journal":{"name":"Contemporary Herpetology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125284859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"THE TAXONOMIC STATUS OF THE WYOMING TOAD, BUFO BAXTERI PORTER","authors":"Hobart M. Smith, D. Chiszar, J. T. Collins, F. Breukelen","doi":"10.17161/ch.v0i1.11929","DOIUrl":"https://doi.org/10.17161/ch.v0i1.11929","url":null,"abstract":"Although discovered by George Baxter in 1946 (Baxter and Meyer, 1982), existence of the Wyoming Toad was apparently fi rst recorded by Stebbins (1954: 143, map p. 145), who learned about it from Baxter (Stebbins, personal communication) and listed it from Albany Co., southeastern Wyoming, under the name of Bufo hemiophrys Cope. The range of that species is otherwise limited to central western Canada and northern parts of the adjacent United States (Montana, North Dakota, Minnesota), southward in the Red River drainage to northeastern South Dakota. Thus a minimum of about 800 airline km separates the range of the Wyoming toad from that of its more northern closest relative (Figure 1). The Wyoming population, abundant within 30 miles (48.3 km) of Laramie in the 1950’s (Baxter and Meyer, 1982), is now thought to be extinct in nature (Baxter and Stone, 1985; Baxter, personal communication), none having been seen in the wild for some ten years, except for captive-bred releases. The species is federally classifi ed as endangered and requires both federal and state permits for any activity involving it (Levell, 1997). However, specimens have been bred very successfully in several zoos and facilities of the Wyoming Game and Fish Department, with hopes of reestablishing the population in sanctuaries within the limits of its historical range. Following his original report, Stebbins continued (1966) to refer the Wyoming population to Bufo hemiophrys, but added a more specifi c range: “along the Big and Little Laramie Rivers to about 15 miles north and 15 miles west of Laramie.” Conant (1958, 1975) and Conant and Collins (1991) mapped, but did not name or discuss in detail this population in their guides to the eastern and central herpetofauna of North America, because this population fell outside the geographic range covered by them. It remained for Porter (1968) to regard the Wyoming population as taxonomically distinct, naming it Bufo hemiophrys baxteri (holotype formerly KRP 5-164, now USNM 166434). That subspecies has been generally accepted since then (e.g., Baxter and Stone, 1980, 1985; Stebbins, 1985; Collins et al., 1978, 1982; Sanders, 1987; ABSTRACT: The population of toads in southeastern Wyoming named Bufo hemiophrys baxteri by Porter in 1968 is presumed to be extinct in nature, except perhaps for released, captive-bred specimens. It is suffi ciently distinct in several respects, and suffi ciently isolated geographically from its nearest relative, B. h. hemiophrys, that it should be regarded as a distinct species, forming a superspecies group with B. hemiophrys.","PeriodicalId":173367,"journal":{"name":"Contemporary Herpetology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127500903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
