24 NOTICES OF SERIALS. 



grohmanni, altus, czjzeki; Nautilus austriacus. The total number of species de- 

 termined amounts to 71, of which 14 occur in the lower, 64 in the Upper Lias, 7 

 being common to both the beds. (Richter) A contribution to the Paleontology of 

 the Thuringian forest; with three plates — p. 87-138. (Unger) The Slate and 

 Sandstone Flora, a contribution to the Paleontology of the Thuringian Forest ; 

 with thirteen plates — p. 139-186. (Heckel) Contributions to the fossil Ichthyo- 

 logy of Austria ; with fifteen plates — p. 187-274. (Diesing) Twelve species of 

 Acanthocephala ; with three plates — p. 275-290. The characters of the Tribe are 

 given, with a general view of the Structure and Embryology. The twelve species of 

 JJchinorrhynchus described and figured are characterized in the author's Systema 

 Helminthum. They were all collected in Brazil by Natterer, except the last, E. 

 turbinella, which forms a peculiar group, characterized by the possession of a dis- 

 tinct receptacle for the haustellum. This species was taken from the intestines of 

 Delphinus hyperodon. 



Part 2nd. Communications not by Members. (Rathe) Observations on the 

 Carotids of Snakes — p. 1-22. Showing that the existence of a single Carotid ob- 

 served in various Ophidians, and treated by Cuvier as a character of the whole 

 class, is actually limited to a certain portion of the wide-mouthed snakes ; the rest, 

 and all the small-mouthed snakes, having a pair of common carotids. (Guembel) 

 Notes upon the dying lichen Lecanora ventosa Ach., with an essay on the develop- 

 ment of Lichenes ; one plate — p. 23-40. 



SlTZUNGSBERICHTE DER K. AKADEMIE DER WlS3ENSCHAFTEN. PROCEEDINGS 



of the Vienna Academy. 8vo. Vienna. 

 Vol. XIX.; in two Parts; with thirty Plates, and three Maps. 1856. 

 Zoology. (Langer) On the calci-tibial joint in Mammalia and Man — p. 117- 

 121. (Engel) On the growth of hairs that have been clipped; with two plates 

 - -p. 240-254. (Heuglin) Classified list of the birds of North-Eastern Africa, 

 including the Arabian coasts of the Red Sea, and the region of the sources of 

 the Nile as far f.outh as four degrees North latitude — p. 255-324. The list 

 comprehends 754 species. (Hyrtl) On Morrayrus and Gymnarchus — p. 94-97. 

 (Diesing) Twelve species of Acanthocephala — p. 97. (Wedl) On the oral 

 organs of the Nematodea ; with three plates — p. 33-69. The Nematodea have 

 no proper head furnished with organs of sense. The knots and papillae, 

 which Siebold, in his Comparative Anatomy of the Invertebrata, has considered 

 as organs of touch, are mere thickenings of the Chitine integument. The oral 

 organs naturally vary much according to the mode of life, and are very compli- 

 cated in many Nematodea. (Same) On some Nematodea ; with a plate — p. 122- 

 134. Filaria flexuosa n. sp., in swellings under the hide of the red deer. F. 

 clava n. sp., from the cellular membrane about the trachea of a house pigeon. 

 Trichosoma pachykeramotum n. sp., from the intestine of the hunting leopard. 

 Trichosoma papillosum n. so., from the intestine of a sheep. Remarks on the 

 g. Trichina. (Frauenfeld) On the genus Carychium ; with a plate — p. 70-93. 

 Of this genus, which is peculiarly attached to the dark and moist nooks of sub- 

 terranean caverns, nine species are admitted. C. amoenum a new species is 

 figured, as well as C. schmidtii, lautum and obesum, the figures of the last two, 

 given in the volume for 1854, not being sufficiently characteristic. (Schmidt) 

 The Embryology of the Najades; with four plates— p. 183-194. Anodonta cyg- 

 nea and Vnio pictorum form the subject of these observations. The mode of 

 development differs in some points from that observed by Leuckart in A. inter- 

 media, showing the prudence of avoiding hasty generalization from particular 

 instances. Geology and Paleontology. (Zeuschner) Geognostical descrip- 

 tion of the Lias limestone in the Tatra and adjoining mountains ; with wood- 

 cuts and two plates — p. 135-182. Ammonites leptoviensis, a fine and very 

 variable new species, described and figured. (Neugeboren) On the Forami- 

 nifera of the order Stichostegia, in the Clay, "Tegel," of Upper Lapugy, in
