IMANTODES SPLENDIDUS SPLENDIDUS (Giinther) 
Dipsas splendida GUNTHER, Biol. Centr. Amer. Rept., p. 176, pl. 56, fig. A., 1895 
(Yucatan). 
Imantodes splendidus Scumipt and ANDREWS, Field Mus. Nat. Hist., zool. ser., 
vol. 20, pp. 176-177, 1936. 
Imantodes gemmistratus HARTWEG and OLiver, Mise. Publ. Univ. Mich. Mus. 
Zool., No. 47, p. 24 (part), 1940. 
Diagnosis —Vertebrals not or scarcely enlarged, none or very few 
approaching twice the width of adjacent scales; usually 3 labials enter 
orbit; all body bands distinct, about 34 to 39, most of them much nar- 
rower laterally than dorsally, only those on posterior part of body 
broken laterally; ventrals 198 to 201. 
Range.—Northern part of the Yucatan peninsula. 
Specimens examined —Two. 
Remarks.—With the restriction of the name gemmistratus to a 
species with larger vertebral scales, sp/endidus becomes available for 
the Mexican species previously called gemmistratus. There are at 
least 3 races, and probably more. 
IMANTODES SPLENDIDUS LUCIODORSUS Oliver 
Imantodes luciodorsus OLIvER, Copeia, 1942, No. 1, pp. 1-2. 
Diagnosis.—Like s. splendidus, except: Dorsal bedy spots 48 to 52, 
average 46, broken laterally on posterior half of body; ventral 205 to 
295, average 219 (14 specimens). 
Range—Coastal or lowland regions on Atiantic slopes from central 
Veracruz through Campeche and northern Chiapas into Guatemala, 
avoiding the northern half of the Yucatan peninsula. 
Specimens examined.—Twelve. 
Remarks.—With the definition of this race closely related to 
splendidus, and the restriction of the name gemmistratus to a species 
of Imantodes with distinctly enlarged vertebral scales, a new name for 
the Pacific coast race, closely related to luciodorsus, is necessary.
