PROCEEDINGS OF THE NATIONAL MUSEUM 

 GEAGRAS REDIMITUS Cope 



Twenty-nine specimens were secured (Nos. 109876-902, HMS Nos. 

 12097, 15722), all from the vicinity of Tehuantepec, Oaxaca. 



This curious snake bears no relationship to Geophis, near which it is 

 allocated by Boulenger. It more nearly resembles T ant ilia, as con- 

 cluded by Dunn. The maxillary teeth are 12 in number, thickened, 

 and flattened at the tips; the two rear teeth are distinctly grooved, 

 distinctly (although not greatly) enlarged, and are preceded by a short 

 diastema. The hemipenis extends to the suture between the sixth and 

 seventh caudals; the distal third (corresponding to two caudal 

 lengths) is covered by calyces, and appears to be capitate; the median 

 third is covered with nearly straight spines; the proximal third is 

 spineless, ridged. The sulcus is single, not divided.
