Mexican Longnose Snake

Rhinocheilus antonii
DUGÈS, 1886
Alamos, Sonora, Mexico. August 21, 2011

Rhinocheilus antonii are very common on the roads at night around Alamos.  Some carry a spotted pattern similar to Rhinocheilus lecontei, but many are unspotted or nearly so, like the beautiful specimens pictured here.  Some workers consider Rhinocheilus antonii to be a subspecies of Rhinocheilus lecontei, and others lump them all into one species (lecontei). To my eye, antonii are a bit bulkier in build than the Rhinocheilus lecontei found further north.

My Flickr album for this species is here.
