The afferent system is more similar to those of Allolobophora and Eisenia than that of Lumbricus. The efferent system is similar to that of Pontodrilus. In segments 17 to 23 the position of the vessels is slightly modified due to a pair of copulatory chambers, whose circulation is like that of the prostates of Pheretima. In segments 7 to 9 the ventro-tegumentary vessels arise from the lateral hearts. Those of 9 which supply the genital organs and anastomose with the ventro-tegumentary vessels of 14, are especially voluminous forming a safety system. From the gizzard forwards the dorsal vessel is replaced by a vessel formed by the coalescence of branches of the ventro-tegumentary vessels of 6. Longitudinal neural vessels are absent throughout the whole body.","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"87 1","pages":"19-36"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89209881","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}

The preoocyte undergoes four differential mitoses and the GB stays in only one cell, the oocyte, the other fifteen becoming nurse cells. The behaviour of this extrachromosomal formation is interesting but its significance is not completely clear, partly because it disintegrates and disappears during growth of the oocyte. Cytochemical study has shown that at its appearance the GB consists predominantly of DNA and at the time of its destruction there is an increasing synthesis of RNA. The results were obtained with a variety of cytochemical and autoradiographic techniques and have been confirmed by various Authors. The nurse cells grow too and their nuclei undergo numerous endomitoses.

Consideration of parasite phylogenetic relationships provides another, independent, view of pipid status. The parasite fauna of Xenopus is highly distinctive and displays a mixture of primitive and very specialised characters. Detailed analysis of one group— the monogeneans— suggests that Protopolystoma, infecting Xenopus, is primitive and very distant with respect to polystomatids in advanced anurans including ranids and bufonids. The combined evidence of a range of invertebrate groups indicates that parasite affinities are best interpreted as a product of prolonged phylogenetic and ecological isolation of the host. It is concluded that pipids are archaic and cannot be aligned with advanced families.","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91513230","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}

Over 150 hr of observation, using the « complete record » sampling method, allowed us to detect a basic diurnal pattern with the highest mean levels in the early afternoon. Such a pattern proved to be fairly uniform under a wide variety of conditions. Statistical analyses showed that only rain and feeding activity influenced it whereas temperature and humidity, in contrast to previous reported studies, failed to prove affective factors. Unlike sex, age affected the daily cycle of allogrooming in that juveniles followed a diurnal pattern different from that of mature individuals. A comprehensive evaluation of these findings suggests that the in-group factors prevail over environmental variables in shaping the diurnal pattern of allogrooming. The nature of such in-group factors (social? physiological?) remains to be investigated.","PeriodicalId":19014,"journal":{"name":"Monitore Zoologico Italiano-Italian Journal of Zoology","volume":"3 1","pages":"149-160"},"PeriodicalIF":0.0,"publicationDate":"2013-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89087330","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}

The vomer and ectopterygoid are without teeth and the hyomandibula is suspended solely from the sphenotic. Of the two prominent fontanels, the posterior frontoccipital fontanel is confined between the frontals and supraoccipital. An additional bone associated with the orbit is reported in this catfish. The circumorbital ring is divided into many tiny pieces. The posttemporal is unforked, lacks the inferior limb and is suturally united with the posterolateral flank of the skull. The occipital process is quite feeble and the posterior part of the skull is not deeply excavated.
