line. A young specimen has only one prseocular, and only the upper smaller 

 temporal is in contact with the postoculars. 



SiMOTES CRUENTATUS. 

 Comp. Proceed A. S. B. for August, 1872, p. 145. 



This species agrees in general aspect and coloration with S. hicatenatus, 

 but it has only seventeen rows of scales. One specimen in the collection 

 has a small portion of a labial detached, forming a second (lower) prseocular ; 

 it has ver}" few dark blotches on the anterior ventrals ; only two black spots 

 on the tail, one at the root, the other near the tip. 



SiMOTES CATEN'IFER, n. sp. PL XI. Fig. 3. 



The body is short, stout, moderately compressed, the head large, conspi- 

 cuously truncate in front. 



Kostral shield well reaching to the upper surface of the head ; anterior 

 frontals considerably smaller than the posterior ones, both bent down at the 

 sides ; superciliaries narrower anteriorly than posteriorly ; vertical large, six- 

 sided, with a very obtuse angle in front, somewhat converging sides, and 

 with nearly a right angle behind ; one occipital is about the same size as the 

 vertical, each reaches down to the superior postocular and is rather broadly 

 truncate behind. Nostril between an anterior large and a posterior some- 

 what smaller shield ; loreal squarish ; two prse-oculars, the upper is long, 

 while the lower has the appearance of being only a small detached portion 

 of the fourth labial ; two postoculars ; temporals 1 -f 2 -}- pL, the last 

 is somewhat irregular and scale -like, the first obliquely in contact with both 

 postoculars. Eight, rarely nine, upper labials, the fom^th and fifth under 

 the orbit, sometimes a small portion of the fourth is detached, touching 

 the orbit as a separate shield. Mental shield small ; nine lower labials, 

 those of the first pair form a suture ; anterior pair of chin-shields largest, each 

 in contact with four labials ; second pair much smaller, and separated by 

 other two somewhat smaller pairs following each other from the first ventral. 

 Scales smooth, in nineteen rows ; ventrals 178 to 205, distinctly angular 

 at the sides ; anal entire, moderately enlarged ; subcaudals bifid, in 57 pairs. 



The general coloration of the upper side is sandy brownish ; head with 

 the usual dark brown markings ; the first band crosses the eyes and reaches 

 forward to the rostral ; the second ascends across the angles of the mouth to 

 the outer median edge of the occipitals ; the third is thick, arrow-shaped, 

 anteriorly prolonged to between the eyes. Body with twelve or tliirteen 

 dark cross bands, each composed of four confluent spots, the two dorsal ones 

 being larger and darker ; tail with four or five cross bands. Between each 

 two of these bands the scales, following alternately each other, are partially 

 blackish, forming three undulating cross lines in each interspace. The sides
