MEXICAN CONIOPHANES FISSIDENS — SMITH 107 



jthrougli the upper edges of supralabials, wliite-edged below; re- 

 jnainder of supralabials stippled, and each (except eighth) with a 

 larger, rounded dark spot near center of light area ; chin, inf ralabial, 

 and gular regions stippled ; some larger black dots on certain infra- 

 labials. Tail with a dark lateral stripe, black-edged above; area be- 

 tween these, on dorsal surface, darker near middle; edges of sub- 

 caudals dark; ends of ventrals dark-spotted; a few small, scattered 

 spots on anterior ventrals ; remainder of ventral surface white. 



Variation. — The single paratype is a male with 120 ventrals, tail 

 tip missing. The scales are in 19-19-15 rows. Supralabials 8, infra- 

 labials 10, one preocular, two postoculars, temporals as described in 

 type. 



Coloration as in type, except dorsolateral light stripes somewhat 

 more evident; a faint, broken, very fine temporal stripe; small dark 

 spots irregularly placed near ends of ventrals. 



Retnarks. — With this subspecies the specimen from Carrizal, Micho- 

 acan (Brit. Mus. No. 1914.1.28.141) is to be associated; also perhaps 

 another from Cafetal Mirador, Oaxaca (A. M. N. H. No. 19748). These 

 are mentioned by Bailey {op. cif., p. 23) ; I have not seen them, nor are 

 counts available. 



This subspecies resembles proterops in the possession of 19 scale 

 rows but differs in having higher caudal and lower ventral counts and 

 eight supralabials. It resembles fissidens in ventral and caudal counts 

 but differs by lacking the regular series of spots near ends of ventrals 

 and by having only 19 scale rows. It resembles punctigularis in belly 

 coloration and number of ventrals and caudals but differs in dorsal 

 coloration, ventral minus caudal count, and by having 19 scale rows.

Diagnosis. — Scales in 21 rows; males with supraanal tubercles; 

 supralabials 8, rarely 7; ventrals 119 to 130 in females, 116 to 125 in 

 males ; caudals 71 to 85 in females, 80 to 91 in males ; ventrals minus 

 caudals 39 to 54 in females, 31 to 38 in males; spots on belly very small, 

 scattered; belly sometimes unspotted (except ends of ventrals, dark 

 as sides of body) ; median border of dorsolateral light stripes very 

 distinct on posterior part of body as well as on tail ; dorsolateral light 

 stripes distinct on much of anterior part of body; a series of spots 

 on each side of middorsal line, about halfway between lateral and 

 middorsal stripe; spots fused with dorsolateral stripe in all except
