isolated and rounded than in E. sirtalis sirtalis, and are some- 

 times not present on some of the gastrosteges. No marked 

 differences between E. sirtalis dorsalis and E. sirtalis parietalis 

 are described here and it seems far-fetched to call E. sirtalis 

 dorsalis a subspecies.

Scutellation same as in E. sirtalis painetalis. Gastrosteges 

 140-170. Urosteges 70-90. Nineteen rows of scales. Seven 

 upper labials. Oculars 1-3. Temporals 1-2, 1-1, or 1-3. 



Color brown or greenish above. Spots usually distinct, some- 

 times obscure, arranged same as in E. sirtalis par ietalis. Dorsal 

 stripe without dark border. Spots often confluent anteriorly. 

 Lateral stripe greenish, lighter than belly. One or two dark 

 spots near the ends of each gastrostege. Top of head brownish. 

 Superior labials greenish, bordered posteriorly with black. 

 Inferior labials and under part of head yellowish white. No 

 red between the lateral spots. 



I have examined several specimens which agree with Cope's 

 description of E. sirtalis semifasciata. The following is Cope's 

 description of that form (10. 1075) : "The peculiarity of the 

 form consists in the fact that on the anterior fifth or sixth of 

 the length of the body the spots of the anterior row extend 

 across the lateral stripe, breaking it up into sections. In many 

 of the specimens the spots of the superior row become opposite 

 to those of the inferior row and join them, and the latter again 

 join a row which is below the lateral stripe. The three rows 

 of spots thus become confluent, form cross-bars, interrupted only 

 by the median dorsal stripe." 



This slight variation in the arrangement of spots does not
