the same locality, but whether their habitats differ 

 or not, I am unable to say. Confinis is common in 

 McLennan County, where it inhabits the river bot- 

 toms. Two specimens of lindheimeri were collected 

 in the hilly country, eighteen miles northwest of 

 Waco, in the same county. Mr. Mitchell reports both 

 subspecies from Victoria. 



95. Callopeltis emokyi Baird and Girard. Emory's 



Pilot Snake. 



Western half of the State, east to Dallas, Waco, 

 Victoria and Brownsville. This species climbs trees 

 but is less active than the different forms of Callo- 

 peltis obsolehis. It is the only species of pilot snake 

 that is found in the breaks and canyons of the plains 

 region. 



96. Callopeltis bairdi Yarrow. Baird's Pilot Snake. 



The type and only specimen of this species is in 

 the National Museum collection. It was collected at 

 Fort Davis, Jeff Davis County. 



97. Callopeltis siibocularis A. E. Brown. 



Davis Mountain Pilot Snake. 



This snake is known only from the Davis Moun- 

 tain district of trans-Pecos Texas. The type was 

 from the head of Toyah creek, Jeff Davis County. 

 A number of living specimens were received at the 

 Philadelphia Zoological Garden and it is probably 

 one of the most distinct species in the genus. 



98. Arizona elegans Kennicott. Kennicott's Snake. 



Known in Texas from only a few widely sepa- 

 rated localities. Arthur Erwin Brown records it 

 from Pecos and Sejonour. Julius Hurter obtained 

 two fine examples near San Antonio. Dr. Boulenger 

 in his Catalogue of the Snakes in the British Mu- 

 seum, records two from Duval County, under the 

 name of Coluber arizonae.
