saurian from the Texan Permian ; while in a third communi- 

 cation, ibid.y pp. 187-96, he gives a very full account of the skull 

 and skeleton of Dimetrodon incisivus — one of those extraordinary 

 reptiles v^^ith enormous dorsal spines to the vertebrae. 



In Geol. It. Pal. Abhandlimgen, ser. 2, vol. viii. pp. 33-46, 

 Dr. von Huene redescribes and figures the typical remains of 

 the well-known labyrinthodont Dasyceps bucklandi from the 

 Permian of Kenilworth, preserved in the museum at Warwick. 

 The skull is compared with those of other stegocephalians, and 

 an appendix added on the homology of the stegocephalian 

 " epiotic " and " supraoccipital" with the corresponding elements 

 of reptiles, especially Pariasaurus, Ichthyosaurus, and Placochelys. 

 The restoration of the occipital aspect of the ichthyosaurian 

 skull taken as a basis of comparison is the one made by Baur, 

 which differs in some details from that given by Andrews in the 

 memoir already cited (p. 684). 



Of papers devoted mainly or exclusively to fishes, the first 

 for notice is one by Dr. E. Stromer on reptilian and fish remains 

 from the marine older Tertiary strata of southern Togo, German 

 West Africa, published in Monatsber. Deutsch. geol. Ges., vol. Ixii. 

 pp. 478-507. With the exception of Varanus niloticus, none of 

 the few reptiles is specifically identified ; but the fishes include 

 species of pycnodonts, rays, and sharks, several of which are 

 new, while the palate of one ray is made the type of the new 

 genus Hypolophites, whose affinities are with Myliobatis. 



Fish-remains from strata of apparently Lower Cretaceous 

 age in the Manse Valley, Cameruns, form the subject of an 

 article by Dr. Jaekel in Beitrdge ziir Geologic von Kamenm, 

 Berlin, vol. x. pp. 329-98. The one form fully described, 

 Proportheus kameruni, represents a new genus and species, 

 regarded by its describer as an annectant type. The pre- 

 servation of the skull is remarkably fine, all the constituent 

 bones being displayed. 



Two other papers on African fish-remains, by Mr. F. Priem, 

 have been published in Bull. Soc. Geol. France, ser. 4, vol. ix. 

 p. 315-26. In the first of these the author describes a number 

 of fish-teeth from the Eocene phosphates of Tunis and Algeria, 

 many of which approximate to those from the Eocene of Egypt. 

 The second is devoted to a new pycnodont {Ccelodus bursauxi) 

 from the upper Senonien of Tunis. Here also may be men- 

 tioned a note by Mr. Wood in the Geological Magazine,
