The Reptilian Order Cotylosauria. 



By E. D. Cope. 



{Read before the American Philosophical Society, November 15, 1895.) 



Ttie characters of this order are as follows: 



Quadrate bone united by suture with the adjacent elements. Temporal 

 fossa overroofed by the following elements: Postfrontal, postorbital, 

 jugal, supramastoid, supratemporal, quadratojugal. Tabular bone 

 present. Vertebrse amphicoelous ; ribs one-headed. Episternum present. 

 Pelvis without obturator foramen. 



This order is of great importance to the phylogeny of the amniote 



*Ia the Ball. Brook. Ent. Soc, Vol. vil, 4, Mr. Smith says of his new Bomolocha that 

 "it is nearest to the te^w^its variety of deceptalis." Nowhere in llie Revision can I find 

 mention of this remarkable variety of deceptcuis, pr. syn. or pr. var. I do not linow what 

 to make of the omission. Now, in the Revision, Mr. Smith adopts Lomanaltes and says 

 that the insect " does convey a somewhat distinctive impression." As in Ayrotis opipara 

 and Oiicocneniis riparia, etc. Mr. Smith's synonymy is here not full ; the omitted refer- 

 ences tell against me and here cover up a remarkable error of judgment on his part.
