on each side by a row of black S[)ecks, situated at intervals of one or 

 two scales, differing in different specimens. On tbe fourth row of scales 

 on each side is another row of specks which are separated by spaces of 

 two scales length. The top of the head posterior to the prefrontals is 

 more or less speckled with dark brown. Labial scuta immaculate.

The specimens show considerable variation in the number of the 

 postocular scuta. Thus in two specimens from Fort Towson, Arkansas 

 (Cat. Xo. 2055), there are three on each side; in Cat. Ko. 12023, from 

 Mount Carmel, Illinois, there are two on each side, and in Cat. No. 

 13632, from Helotes, Texas, the two are fused into a large one on each 

 side. 



The differences between this species and the V. valericv are restricted 

 to the form and number of the scales. Beyond these I have not been 

 able to detect any.

Head not distinct; teeth equal. Scales keeled; anal and subcaudal 

 scuta divided. Cephalic scuta of upper surface normal. Eostral not 

 prominent; two iuternasals. Two nasals, one loreal which extends to 

 the orbit. No preocular. Pupil round. 



This genus embraces, as yet, but a single si)ecies. It is most nearly 

 allied to Haldea, from which i t differs only in the presence of two inter- 

 nasal plates. The species is little known.
