DistributionS Canada (incl. Saskatchewan, Manitoba, Nova Scotia, New Brunswick, Ontario, Quebec, Prince Edward Island),
USA (scattered in North Dakota, South Dakota, Nebraska, Minnesota, Montana, Iowa, Missouri, Wisconsin, Illinois, Michigan, Indiana, Ohio, West Virginia, Virginia, Maryland, Pennsylvania, New Jersey, New York, Connecticut, Massachusetts, Vermont, New Hampshire, Maine; Colorado [HR 32: 60], Texas),
Mexico (Chihuahua)

Type locality: E Pennsylvania or New Jersey (fide GROBMAN 1941).

blanchardi: USA (Colorado, Indiana, Kansas, Missouri, Nebraska, Illinois, Ohio, New Mexico, North Dakota, Utah, Wyoming, South Dakota, SE Texas), Canada (Manitoba); Type locality: Spanish Peaks, 8,000 feet, Colorado.

borealis: Canada (Nova Scotia); Type locality, "Wilson Cove, Guysborough County, Nova Scotia."  
ReproductionTypically oviparous but some females appear to have “facultative” viviparity (BLACKBURN 1999). Egg retention is protracted, with a maximum postpositional fetal period of about 30 days (Oldham and Smith 1991, cited after Walley 2003). 
TypesHolotype: lost, originally ANSP (lost fide Grobman 1941: 10, Wallach et al. 2014)
Holotype: UMMZ 62439, Paratypes: UMMZ, USNM, LMK, FMNH [blanchardi]
Syntypes: NMC 25237 (Nova Scotia Museum of Canada), and CMNAR 25237 collected by J. Gilhen and E. Odense, 4 July 1973 [borealis] 
DiagnosisAdditional details, e.g. a detailed description or comparisons (2551 characters), are available for collaborators and contributors. Please contact us for details. 
CommentSynonymy mostly after GROBMANN 1941 and WALLEY 2003. The genus Eurypholis is pre-occupied by a fossil fish.

Distribution: after GROBMANN 1941; see also map in WALLEY 2003. A single record from North Carolina is most likely in error (Stuart et al. 014).

Subspecies: after WALLEY 2003 who does not recognize any subspecies. Supposedly, O. v. blanchardi is characterized by a greater number of ventrals [holotype: 138](<140 in females and <131 in males of vernalis). Named after Dr. Frank Blanchard. Similarly, Grobman 1992 diagnoses borealis as a “A smooth-scaled Opheodrys closely related to 0. v. vernalis,from which it differs most conspicuously in having a lesser number of ventrals. Ventrals in females usually less than 127; usually less than 119 in males.”

Habitat: O. vernalis largely terrestrial, seldom found climbing into
bushes (partly arboreal), whereas O. aestivus is strongly arboreal. 
EtymologyNamed after Latin “vernalis” for "of springtime."

The generic name Liochlorophis is a combination of the Greek words lio, chloro, and ophis, meaning, respectively, smooth, green, and snake, in reference to the smooth scales and dorsal coloration.
