42. Plestiodon brevilineatus (Cope) Short-lined Skink 



Eumeces brevilineatus Cope, Bull. U. S. Nat. Mus., No. 



17, 1880, p. 18. 

 Marnock collected the types of this species near Helotes. 

 Seven specimens from the same locality and collector are in the 

 Baylor University collection and one in the museum of the Scien- 

 tific Society. The last mentioned specimen was labelled 

 Eumeces inornatus Baird by Mr. Marnock, who presented it to 

 the society. Louis Garni collected this species in Kendall Coun- 

 ty only a short distance from the Bexar County line. It is 

 probably widely distributed in "Bexar County in all of the rocky 

 districts. 



43. Plestiodon obsoletus Baird and Girard Sonoran Skink 



Plestiodon obsoletum Baird and Girard, Proc. Acad. 

 Nat. Sci. Phila.. Vol. 6, 1852, p. 129. 



This interesting skink is found in suitable localities 

 throughout Bexar County. A small series from Helotes, col- 

 lected by Mr. Marnock, is most interesting as it includes speci- 

 mens of all ages and types. Stejneger and Barbour are prob- 

 ably right in their suggestion that Plestiodon guttulatus Hallo- 

 well is the young of this species. One of the young examples 

 from Helotes is almost indistinguishable from a guttulatus of 

 the same age from El Paso. 



44. Leptotyphlops dulcis (Baird and Girard) Worm Snake 



Rena dulcis Baird and Girard, Cat. N. Am. Rept., Pt. 1, 

 1853, p. T42. 



This tiny, worm-like serpent is abundant in many sections 

 of Bexar County. Mr. Brimley has received it from the City of 

 San Antonio, Mr. Garni found it common on the grounds of St. 

 Louis College and Mr. Marnock collected a large number at He- 

 lotes. I found quite a number under stones on hills and along 

 stream beds a short distance out from San Antonio. 



45. Diadophis regalis Baird and Girard Regal Ring-necked 



Snake 

 Diadophis regalis Baird and Girard, Cat. N. Am. Rept., 



Pt. 1. 1853, P- "5- 

 This species is abundant in the vicinity of Helotes but has 

 not been recorded from any other part of the county. Among 

 the specimens in an unlabelled jar in the Marnock collection, I 

 found several specimens of Diadophis arnyi Kennicott. These 

 may have been collected in Bexar County but I am doubtful 

 about it.
