GBIFID: 1306572629; Occurrence Remarks: Night snake. I know this as Hypsiglena torquata, but a recent web search showed Hypsiglena chlorophaea. Is this a name change or a different species? Description: A small (up to 598 mm or 23 in total length) gray, or tan snake with small, dark, gray-brown blotches on the back (dorsal blotches). The dorsal blotches are usually in a single row but are sometimes offset at the midline of the back creating two rows of small, alternating blotches. A dark collar, usually consisting three gray-brown blotches marks the neck. In some south-central Arizona specimens the lateral collar-blotches are fused to the dorsal collar-blotch. The central collar-blotch is relatively broad (compared to our other Hypsiglena) with a thin spine extending anteriorly. A dark gray-brown bar extends back from each eye and expands into the lateral collar blotch. The underside is plain pale gray. The head is relatively flat. The pupils are vertically elliptical and the scales are smooth. -copied from Reptiles and Amphibians of Arizona http://www.reptilesofaz.org/;; Coordinate Uncertainty in Meters: 6954.00000.
