SMITH 395 
MEXICAN HERPETOLOGICAL MISCELLANY 
latter is a species I have not seen, and it is not represented in the 
collection of the United States National Museum. It possibly be- 
longs in the group with pulcher and lineatus, since it has eight 
supralabials and presumably the first scale row pigmented. It seems 
closest to pulcher, of which it could conceivably be a race. It cer- 
tainly is a species different from /éneatus, which also occurs in Costa 
Rica. . 
The Central American subspecies of lineatus, which I named 
similis, cannot stand, since it is a homonym of Conophis pulcher 
similis Bocourt.?* I suggest the name dunni for the southern race; 
its type (that of s¢mdlés Smith) is U.S.N.M. No. 79963, from Ma- 
nagua, Nicaragua. 
Unfortunately Bocourt’s pulcher similis was described without ci- 
tation of the type locality, and many details of its pattern are not 
mentioned. However, in several respects it agrees with C. pulcher 
plagosus, which I described on the basis of a single specimen from 
Tonala, Chiapas (U.S.N.M. No. 109707). Although absolute cer- 
tainty of the identity of Bocourt’s specimen can be obtained only by 
reexamination of the type, it appears probable that plagosus Smith 
and simélis Bocourt are identical. 
The species of the genus accordingly stand as follows: 
Conophis vittatus vittatus Peters 
Conophis vittatus viduus Cope 
Conophis pulcher pulcher Cope 
Conophis pulcher similis Bocourt 
Conophis nevermannt Dunn 
Conophis lineatus lineatus (Duméril and Bibron) 
Conophis lineatus concolor Cope 
Conophis lineatus dunni Smith.
