558 THE BAYLOR BULLETIN 



in the Brown list, on the stren^h, so the author 

 wrote me, of one of Cope's references ("from San 

 Diego, Duval County." Proc. U. S. Nat. Mus., p. 397.) 

 I have not seen the article, but am satisfied that a 

 mistake has been made somewhere. In Cope's "Ba- 

 trachians and Reptiles of Central America and 

 Mexico" (Bull. U. S. Nat. Mus., No. 32) Chrysemys 

 ornata is recorded from the following localities: 

 Presidio (Forrer), Mazatlan (Forrer, Colley), Costa 

 Rica and Panama. As specimens sent to the British 

 Museum from San Diego are likely to have been col- 

 lected in almost any other locality, I am not always 

 surprised at some of the species that are supposed to 

 have come from there. 



2. SCELOPORUS JAREOVII Cope. Yarrow's Lizard. 



Recorded from Duval County by Dr. Boulenger 

 (Proc. Zool. Soc, London, 1897). A common species 

 in Arizona and the State of Sonora, Mexico, but not 

 likely to occur in the locality mentioned. This rec- 

 ord, unless the locality label is incorrect, may be 

 based on a melanistic specimen of Sceloporus torqua- 

 tus poinsettii. It is hardly probable that three such 

 closely related forms as ornatus, jarrovii and poin- 

 settii should occur in the same locality. 



3. Helodekma suspectum Cope. Gila Monster : Beaded 



Lizard. 



Cope, in the Report of the U. S. National Museum 

 for 1898, page 483, lists a specimen of the poison 

 lizard from Fort McDowell, Texas. If this species 

 really occurs in Western Texas, it seems strange that 

 no specimens have been obtained there in recent 

 years by the different parties of zoological collectors 

 that have traversed that region. I carefully searched 

 several localities where Gila monsters were supposed 

 to be found, but without success. At Elephant Mesa 

 Brewster County, we saw many large specimens of
