Kinosternon flavescens (Agassiz). 



One specimen. San Antonio, Tex., of a well-marked Texan form, 

 which Mr. Arthur Erwin Brown has identified with Agassiz's species 

 as above. 



Aromochelys odoratus (Dand.t. 



One example from San Marcos. Tex., which seems to be identical 

 with the eastern species. Should it prove to be separable, Agassiz's 

 name tristycha wquIcI apparently be available (type loc, ''Osage river, 

 Mo., and Williamson county, Tex."). The differences he points out 

 — snout more prominent and lower jaw broader below the symphysis — 

 while perceptible in the present specimen, are not sufficient for separa- 

 tion -v^dthout the examination of more material. 

 Crotophytus coUaris (Sayi. 



One specimen each from San ^larcos and Devil's ri^■er. Tex., and two 

 from South McAlester, I. T. 



None of these have two rows of interoculars. 



Holbrookia texana (Troschel). 



One example from Devil's river, Tex. 



Sceloporus undulatus (Latreille). 



Specimens from the following localities: Chadwick, Mo.; jMagazine 

 Mt. and Petit Jean Mt., Ark.; Wister, Limestone Gap and Sugar Loaf 

 Mt., I. T. 



These have the head scales smooth and color as in eastern examples, 

 though a specimen from Wister shows some approach to the next. 

 Sceloporus undulatus consobrinus (Bd.'and Girard). 



Two from San ]\Iarcos, Tex., much lighter than the preceding, with 

 the spots on the back shorter and brighter. 

 Sceloporus couchii Baird. 



One specimen of this interesting species from Devil's river, Tex. 

 Although Cope does not record this species from within the boun- 

 daries of the United States, Boulanger obtained one from Duval 

 county, Tex. 



The specimen secured b}" Dr. Pilsbry seems to be perfectly typical. 

 Phrynosoma cornutum (Harlan). 



Three examples from Del Rio, Tex., and one from Devil's river. 



The occipital spines are more nearly perpendicular and the ventrals 

 more carinated than specimens from Alamogordo, X. M. 



Cnemidophorus gularis Bd. and Girard. 



One specimen from San Marcos, Tex., is true gularis in scale pattern^ 

 but the spots are fewer and restricted to the dark areas between the
