this species. It lias 229 veiitmls, and 29 bifid siibcaudals. 

 On one side there are seven labials, second and third in 

 orbit, on the other there are eight, third and fourth in orbit. 

 There are 24 + 2 yellow rings ; the red are much spotted 

 with black, and each is about as wide as one of the black 

 plus two of the yellow. Tail black and yellow. 



Tropidonotus obliquus Hallow. 



This type agrees with T.fasciatus in structural details, 

 but differs greatly in coloration. Rows 23, ventrals 132, 

 labials 8, infralabials 10-11, 1 anteorbital, 3 postorbi- 

 tals. Across the back there are about sixteen blotches 

 of black separated by irregular obliquely transverse narrow 

 streaks of yellowish that widen on the flunks. Toward 

 and on the ventrals the blotches become reddish and more 

 or less bifid. The first blotch is a wide one and extends 

 forward on the neck and top of the head to the rostral. 

 The margins of the labials have very little of the brown 

 color, and the bar behind the eye is partially obliterated 

 and indistinct. In the Mus. Comp. Zool. there is another 

 specimen of this form, from Dallas, which has rows 23, 

 scutes 135, subcaudals 77, labials 8, and infralabials 10- 

 11. On this one the brownish red of the blotches extends 

 nearly half way across the lower surface. Tail uniform 

 dark brown. 



This form is close to the type described by Hallowell 

 from Kansas, but differs in the number of blotches, unless 

 they are counted along the outer rows of scales on the 

 flanks. His specimen had 140 ventrals, 69 subcaudals, 

 and 32 + 18-19 blotches. On the young no doubt the 

 blotches are less confluent. 



Tropidonotus trans versus Hallow. 



Of ten specimens the first two have 23 rows, the third 

 27, and the remainder 25 rows each. Their scutes, anal
