RUMINANTIA CERVIJVAE CERVUS COLUMBIANUS. 



663 



I am in some doubt as to the true characters of the Cervus lewisii and punctulaius of J. E. 

 Gray. The former is described as very similar in its horns to the C. virginianus, but wanting 

 the basal snag. Now, the basal snag is more frequently present than absent, and the horns are 

 unlike those of C. virginianus. The most essential characteristics of the species are omitted. 

 A similar uncertainty applies to the Cervus punctulatus. I have not at hand his figures of either 

 species, and cannot therefore use them in ascertaining whether they are synonyms here, or of 

 C. leiicurus, but have provisionally placed them with C. columbianus. 



List of specimens.
