t. Hist., ser. 3, 5:170.--Laguna Island, Nicaragua (in error). _Hypsiglena torquata torquata_, Taylor, Univ. Kansas Sci. Bull., 25:371, July 10, 1939. Apatzingan; Capirio; Cofradia. Specimens from the three mentioned localities have the dark nuchal spot bordered anteriorly by a pale blotch. In life the specimen from Capirio (UMMZ 114424) had rich reddish brown dorsal spots; the dorsal ground color was grayish white above and somewhat more gray laterally. The pale nuchal area was a cream-color, and the iris was grayish red. All of the specimens were found in the arid scrub forest in the Tepalcatepec Valley at elevations between 200 and 350 meters. ~Imantodes gemmistratus gracillimus~ (Guenther) _Dipsas gracillima_ Guenther, Biol. Centrali-Americana, Rept., p. 177, July, 1895.--southern Mexico. Type locality restricted to Acapulco, Guerrero, Mexico, by Smith and Taylor (1950a:331). _Imantodes gemmistratus gracillimus_, Zweifel, Amer. Mus. Novitates, 1961:12, September 16, 1959. La Orilla. The specimen from La Orilla was reported by Peters (1954:23) as _Imantodes gemmistratus oliveri_; Zweifel (1959c) showed that _I. g. oliveri_ did not range west of Tehuantepec and that the snakes inhabiting the coastal lowlands of Guerrero, Michoacan, and Colima were assignable to the subspecies _gracillimus_. It may be assumed that this subspecies ranges throughout the coastal lowlands and foothills of the Sierra de Coalcoman. ~Imantodes gemmistratus latistratus~ (Cope) _Dipsas gemmistrata latistrata_ Cope, Bull. U. S. Natl. Mus., 32:68, 1887.--Southern Jalisco. Type locality restricted to Guadalajara, Jalisco, Mexico, by Smith and Taylor (1950a:334). _Imantodes gemmistratus latistratus_, Zweifel, Amer. Mus. Novitates, 1961:3, September 16, 1959. El Sabino. The one specimen from Michoacan was collected near the upper limits of the scrub forest on the slopes of the Cordillera Volcanica. Zweifel (1959c:10) stated that in certain aspects of coloration this specimen was like _I. gemmistratus gracillimus_, but in scutellation and other features of coloration it was like _I. g. latistratus_. There are too few specimens of this species to define the ranges of the various subspecies with any degree of accuracy, but from the limited number of specimens available, it seems that _I. gemmistratus gracillimus_ occurs on the
