CommentDiagnosis. Brevis may be distinguished from the southerly members of the genus by the absence of enlarged tubercular scales among the granular scales of the dorsum. Although the characters first used by Stejneger to distinguish brevis from variegatus, proved, with the availability of more material, to lack consistency, the species are indeed different, other divergences having been discovered. H. M. Smith, in 1933, pointed out that the preanal pores are fewer in brevis (seldom other than 4), and are separated into two lateral series by unpitted scales at the apex, while in variegatus thetwo series contact at the apex; he also discussed the pattern differences, and differences in the doacal spurs. In brevis the supranasals are somewhat smaller and more widely separated than in variegatus. From fasciatus, brevis may be distinguished by the lower number of anal pores and by the spotting of the adults [from KLAUBER 1945: 185]. 
EtymologyNamed after Latin “brevis, -e” = short.
