This species belongs to the Austroriparian region, but has not been 

 found up to date as far west as the Mississippi Eiver. I detected it in 

 1895 on the Pamunkey Eiver, in Virginia. This locality has always 

 been regarded as within the Carolinian district, so that the locality is 

 unexpected.

This species is a burrower, and is allied to CarphopTiiops, as I first 

 pointed out. The Pamunkey Eiver specimens were dug from a clay 

 bank beneath ten feet of sand. Mi. Clarence B. Moore, in his excava- 

 tions of Indian mounds in Florida, has dug it from nearly as great a 

 depth beneath the surface, in sand. This species and the Farancia 

 ahacura are the largest of the burrowing Dromicinse.

Head subelliptical, elongated, slightly distinct from the body. Inter- 

 nasal plate single. One nasal, grooved beneath the nostril. No pre- 

 orbital; prefrontal and loreal constituting the anterior portion of tlie 

 orbit. Postorbitals present. Scales smooth. Postabdominal scutelhi 

 bifid. Subcaudal in pairs. Teeth equal. Hemipenis bifurcate, with a 

 moderate number of dentate calyces, and numerous spines. 



In the only species of this genus known the spines of the hemii)enis 

 are much larger and less numerous than in Abastor erytlirogrammMS. 

 In both genera the character is different from the allied South Amer- 

 ican Fseudoeryx. 



This genus is known only from the Louisianian and Floridiau dis- 

 tricts of the Austroriparian region. It does not occur in the Texan
