 Morelos ; and No. 110397, 5 miles south of Carapa, Michoacan. 



In the smallest (No. 110397) the nuchal light collar crosses the 

 tips of the parietals ; in the other two the collar borders the posterior 

 edges of the parietals. Two tiny, juxtaposed pineal light spots in 

 two (Nos. 110395, 110397) ; an irregular, small light spot at anterior 

 edge of parietal; a light spot on anterior edge of supraocular faintly 

 visible; a larger light spot on each internasal; a middorsal dark 

 stripe very faintly indicated in two (Nos. 110395, 110397). The 

 young specimen is considerably darker above than the other two. 

 The Cuernavaca specimen is more flesh-color above, while the Tehua- 

 can specimen is light gray. There is faint evidence of pigment on 

 the lower labials. 



The secondary temporal is scalelike (about as long as broad), the 

 sixth labial is higher than the fifth ; the first infralabials are in con- 

 tact medially; the frontal is broadest in the Michoacan specimen
