VERTEBRATE PALEONTOLOGY IN 1913 651 



course, as the specific) being apparently new, although this is 

 not definitely stated to be the case. The broad flattened head, 

 coupled with the short and nearly straight ribs, suggests 

 relationship to the Protritonidce (Branchiosauridce). 



In Europe Dr. E. Fraas has described {Palccontographica, 

 vol. lx. pp. 275-94) several new species of large labyrinthodont 

 stegocephalians from the Swabian Trias, one of which is 

 referred to Cyclotosaurus, as typified by Meyer's Capitosaurus 

 robustus ; the genus also including the so-called Capitosaurus 

 stantonensis of the Warwickshire Keuper. And from the Trias 

 of Heligoland Mr. H. Schroeder has described and figured 

 (K. preuss. Geol. Landesanstalt for 1913) a beautifully preserved 

 skull of a member of the same group as a new species of the 

 genus typified by Meyer's Capitosaurus nasutus, from the Trias 

 of Bernberg, under the name of C. heligolandi. 



Yet another paper on stegocephalians is to be found in the 

 Proceedings of the Zoological Society for 191 3 (pp. 949-62), in 

 which Mr. D. M. S. Watson discusses the osteology and rela- 

 tionships of Batrachiderpeton lineatum, a genus and species from 

 the Coal Measures of Northumberland originally described by 

 Messrs. Hancock and Atthey. Its nearest known relative 

 appears to be Ceraterpeton of the Kilkenny and Staffordshire 

 Coal Measures, from which it differs by certain features in the 

 structure of the skull — notably the greater development of the 

 posterior "horns"; all such points of distinction being in 

 the direction of greater specialisation. A still more specialised 

 type is represented by Diplocaulus, in which not only are the 

 " horns " still longer than in Batrachiderpeton, but the nasal 

 bones, which are small in the latter, have altogether disappeared. 



Mr. Watson {Geol. Mag. decade 5, vol. x. pp. 340-46) has 

 also reviewed in the light of recent knowledge the skull of the 

 small South African temnospondylous amphibian described by 

 Prof. Huxley in 1859 as Micropholis stowi. 



Finally, remains of two stegocephalians from the Permian of 

 Texas are described by Mr. F. Broili in the Neues Jahrbuch fur 

 Min. 1913, vol. i. pp. 96-100; one of them, apparently allied to 

 Diplocaultis, being referred to a new genus and species under 

 the name of Goniocephalus willistoni, while the second is made 

 the type of the new species Acheloma casei. 



Premising that as my acquaintance with the year's literature 

 relating to fossil fishes is very imperfect, my review of this
