ON THE ZOOLOGICAL POSITION OF TEXAS. 23 



Tex., by Mr. Gabriel W. Marnock. I did not see it elsewhere, and it 

 does not appear to be common. 



Eutccnia cp'topsis Kenn. may be defined as E. sirtalis, with eight 

 superior labials, a red dorsal baud, and the black lateral and nuchal 

 spots very distinct. It belongs to the Sonoran district, and occurs as 

 far south as Guanajuato, accompanying the E. sirtalis. The form ocel- 

 lata is characterized by the anterior interruption of the dorsal and lateral 

 bands by t)ie enlarged black spots, producing the color-ijattern above 

 described. 



Eutcenia sirtalis L. var. ohscura Cope. Found by Mr. Boll near Dal- 

 las. I did not meet with the species in Western Texas. 



Eiitcvnia faireyi B. & G. From Dallas, but not seen in Western Texas. 

 The scutellation of the onlj- specimen obtained is very near that of E. 

 proxima, viz, 1G7-1-105. 



Eictamia proxima Say. The common species of Western Texas, and, 

 like the E, saurita, aquatic in its habits. From Helotes and the heads 

 of the Medina and Colorado. Baird and Girard report it from Indian- 

 ola and the Eed Eiver. It does not occur in the DaUas collections. The 

 dorsal band is a lively red in life. 



EiadopMs puiictatus stictogcnys Cope. From Helotes; not rare. 



OpMbolus getulus sayi Holbrook. A variety of this multiform species 

 was taken near Dallas by Mr. Boll, in which the black ground color is 

 varied by narrow oblique yellowish lines which extend along one and 

 rarely two scales. 



Opliiholus getulus getulus L. The form with yellow cross-bands instead 

 of white, from Helotes. 



Bliinochilus lecontei Bd. and Gird. From Helotes; G. W. Marnock. 

 The most eastern locality known for this species, which is also found in 

 California. 



Phimothyra grahamicc Bd. & Gird. Another species of the Sonoran 

 fauna found by Mr. Marnock near Helotes, marking its most eastern 

 known range. 



Cyclophis wstivus L. Common in Western and i)robably Eastern 

 Texas. 



Coluber emoryi Bd. & Gird. Abundant near Dallas, at Helotes, and 

 west of the Upper Brazos Eiver. 



Coluber UndJieimeri B. & G. Found near Helotes. 



Fltyopliis sayi mexicanus D. & B. From Helotes ; also from near the 

 Wichita Eiver, in Archer County, near the northern boundary. JMr.
