REPTILIA. 



Mr. Theobald^ has recently described a turtle from Thayet Myo on the Irawady,

 skull of T. peguensis. Theobald recognized this, but remarks^ that the plastral 

 characters indicated a totally different animal, and that the style of the coloration 

 of the head was so different from that of T. peguensis that it clearly belonged to some 

 other species. In connection with these remarks, however, by Mr. Theobald, it must 

 be borne in mind that he regarded the turtle figured by him under the name of 

 T. stellatus as the equivalent of T. peguensis — a view of the question I cannot adopt, 

 after reading Dr. Gray's first description of T. peguensis, and after having compared 

 the specimen I have figured under this name with the type of T. peguensis. 



It is further stated by Mr. Theobald that the dried head of the specimen which 

 served as his type of T. grayi when moistened with water closely resembled the 

 coloration of the head he has figured under the name of T. pliayrei, and which he 

 also names T. careniferus, Gray (?), from which, however, he was prevented identify- 

 ing it, as the plastron of T. grayi was covered with granulations. The skull of
