SoELOPORUS viviPARUs Cope, sp. nov. 



Scales of back in parallel series, rather large, eight in a head length, 

 strongly keeled and mucronate. Lateral scales but little, abdominal scales 

 a good deal smaller than the dorsals. Lateral series not very oblique. 

 Head scales entirely smooth. One row of wide supraoculars, separated 

 by one row of very small scales from the supraorbitals, and two rows from 

 the superciliaries. Anterior frontal undivided ; interparietal subquadrate ; 

 two parietals on each side. Preauricular scales not larger than temporals ; 

 two canthals. Posterior foot reaching to front border of ear meatus when 

 leg is extended. Femoral pores fifteen. Length of head a little less than 

 one-fourth that of head and body. 



Color of males above brown, sometimes green ; of a female, green. 

 Sides of belly blue with a dark internal border ; belly, breast and chin 

 straw-color. A black spot in front of the shoulder, which rises into a 

 pomt just above the humerus, but joins its fellows by a black line round 

 the throat. In front of it, the throat is, for a short distance, pale blue. In 

 the female there are some indistinct dark spots on the sides of the back. 



Four specimens from Orizaba, Vera Cruz, Siimichrast ; one from Mira- 

 dor, Sartorius ; and one from Tehuantepec, Su?nichrast. The last named 

 has two rows of larger supraocular scales. The female from Orizaba con- 

 tains in the oviducts six well-formed young not enclosed in egg shells, 

 vphich shows that the species is viviparous.
