KU 73503, 83403); and 82, 90, 86, 89 dorsals. One juvenile of unknown
sex has 8-8 supralabials, 9-9 infralabials, 249 ventrals, 106
subcaudals, and 88 dorsals.
The six larger specimens are gray dorsally in preservative. The
smallest individual has 61 blotches on the body and 42 on the tail.
All specimens agree with the description by Dowling (1960:74-75).
Elaphe triaspis is a nocturnal species in Sinaloa, and apparently is
active later in the rainy season than many other snakes. Less than
20 per cent of the specimens were taken earlier than July 20.
Distribution in Sinaloa.—Probably occurs throughout the state
with the possible exception of the arid northwestern lowlands. See
Fig. 64.

Geagras redimitus Cope
Geagras redimitus Cope, Jour. Acad, Nat. Sci. Philadelphia, ser. 2, 8:141,
1876 (type locality, Tehuantepec, Oaxaca).
Remarks.—Inclusion of this species is based on the original description
of Sphenocalamus lineolatus by Fischer (1883:5), who
gave the locality as Mazatlan but did not designate the state.
Sphenocalamus lineolatus was later referred to the synonymy of
Geagras redimitus by Cope (1885-177). Duellman's report (1961:
96) of two specimens from the lowlands of Michoacan supports
the possibility that Geagras redimitus occurs along the coast from
Oaxaca to Sinaloa.
Distribution in Sinaloa.—Known only from Mazadan. See Fig. 65.
Specimens examined.—None.
Additional record.—Mazatlan (Cope, 1887:82; Fischer, 1883:5).
