Eutaenia marciana B. & G. 

 Eutaenia eques (Reuss). 



Nineteen specimens, all from the Davis Mountains. The dorsal 

 stripe is yellow, often more or less orange; the laterals pale greenish.' 

 Ventrals 151-174; siibcaudals 64-86. Occasionally there are nine 

 upper labials. One of these specimens 700 mm. long has a very short 

 tail, only .17 of the length. 



Tropidonotus clarkii (B. & G.). ., 



Tropidonotus rhombifer Hallow. 

 Tropidonotus sipedon transversus Hallow. 



All the specimens received were light in color, with the markings so 

 obscure as to be distinct only in the young. 



Salvadora grahami B. & G. ^ 



Zamenis flagellum flagellum (Shaw). ' j 



Most of this form from Pecos have been of large size and pale color; 

 Some show more or less of the narrow cross-bands, as in Z. f. frenatvM; 

 some have wide cross-bands, as are seen at times in Z. t. ornatus. 



Two large ones, about 1,700 mm. long, were buff on the back, with 

 distinct wide dark cross-bands. Top of head and ventrals pink, with 

 darker red spots on the throat. '

Eight specimens of this species have been collected, as far as is known J 

 In addition to the four on which the original description was based, two 

 more were received at the Zoological Gardens in 1902, and the New 

 York Zoological Society has also received two, one of which was courte- 

 ously sent me after death by Mr. R. L. Ditmars. The three now in 

 my possession have the scales in 33 rows, and the upper labials 10-11* 

 All seem to have come from the Da^ds Mountains. ' '
