HISTORICAL REVIEW I3 



as a Lacertilian, instead of a Rhyncocephalian, and closely related in habits 

 to the Amphisbcenians. 



In October of 1908, before the appearance of Broili's paper just cited, 

 Williston (69) described the skull of Lysorophus and objected strongly to 

 Broili's reference of the genus to the Rhyncocephalia and considers it as an 

 amphibian. This conclusion was reached independently of Case. Williston 

 proposes the family name Lysorophidce to replace the Paterosauridce, as the 

 last is not according to the rules of nomenclature. He says: "My con- 

 viction is that the Lysorophidce should be included in the Icthyoidea.^' 



Moody, in a paper read before the Kansas Academy of Science and pub- 

 lished in the " Geological Magazine " in 1909 (61), proposed the following 

 arrangement of the Amphibia: 



Class Amphibia. 



Subclass I. Euamphibia. Subclass II. Holospondyli. 



Order i. Branchiosauria. Order i. Microsauria. 



Order 2. Apoda. Order 2. Aistopoda. 



Order 3. Caudata. Order 3. Diplocaulia. 



Suborder i. Proteida. Subclass III. Stegocephala. 



Suborder 2. Meantes. Order i. Temnospondyli. 



Suborder 3. Mutabilia. Order 2. Stereospondyli. 



Order 4. Salientia. 



Suborder i. Aglossa. 



Suborder 2. Linguata. 



Suborder 3. Costata. 



It is regarded as doubtful whether the proposed order Diplocaulia should 

 be placed in the second or the third subclass. 



In 1910 Broom (l), in the "Bulletin of the American Museum of Natural 

 History," called attention to resemblances between the South African and 

 North American Reptilia and Amphibia. 



In the same year Case (19) published in the same journal an account of 

 several new Amphibia and Reptilia from Texas. The new forms of Amphibia 

 were: 



Order Temnospondyli. 



Family Aspidosauridce nov. 



A. glascocki g. et sp. nov. 

 Family Trimerorachidcs. 



Tersomius texensis g. et sp. nov. 

 Trimerorhachis alleni sp. nov. 



A new suborder with a single known family and species was referred to the 

 Reptilia, but in this paper it is referred with query to the Amphibia. 



Suborder Gymnarthria nov. 



Family Gymnarthridce fam. nov. 

 G. willoughbyi g. et sp. nov. 



A study of Broili's type material, after this paper was written, revealed 

 the fact that the specimen was very closely related to his Cardiocephalus, 

 and the two are here united in one family.
