 recording specifically Samburg and Raleigh. 



Carphflphis ainocna (Say). — The single specimen examined 

 (U. S. N. M., No. 44365, Danville, Houston County), 

 a female, is typical in coloration. The scale rows are 13 ; 

 upper labials, 5; lower labials, 6; post oculars, i. There is 

 only a single posterior temporal on each side. This specimen, 

 as well as the one recorded by Rhoades from Raleigh, Shelby 

 County, lacks the internasals. This is also true of a good 

 many middle western specimens. It is not improbable that 

 this character will prove of more geographic significance than 

 hitherto supposed, and that a revision of the genus will assign 

 these western Tennessee specimens to the western race, C. 

 vermis (Kennicott). The ventrals are 128, the caudals 28, the 

 length 253 mm., the tail 0.146 of the length. 



Diadophis punetatus strictogenys Cope. — This name, given 

 by Cope to a specimen with locality unknown, seems to belong 

 to a race occupying the lower Mississippi Valley south from 

 southern Illinois, the essential features of which are a low 

 number of ventrals, 15 rows of dorsal scales, 7 upper labials, 

 and more or less irregular or scattered black spots on the 

 belly. In the first two characters it is identical with punetatus 

 from the southeastern states, in the second it agrees with 

 edi'.'ordsii. and in the third with arnyi. The ventral spots in 

 Strictogenys are not so neatly arranged in twos as they are in 

 arnyi, nor are they in a single, well-defined row' along the 

 middle of the belly as in punetatus, but are irregularly arranged 

 in the center, often partially fused into a single line. 



The eastern ring-neck snakes may be provisionally defined
