cimens were found beneath rocks in tropical
semi-deciduous forest at an elevation of 15 meters on the coastal plain.

~Geophis dugesi~ Bocourt

_Geophis dugesii_ Bocourt, Miss. Scientifique au Mexique et
dans l'Amerique Centrale, Rept., livr. 9:573,
1883.--Tangancicuaro, Michoacan, Mexico.

Carapan; Tangancicuaro; Zacapu.

Aside from the three specimens listed above, there are two (SU 4407-8)
bearing the data "Michoacan." Bocourt (1883:574) stated that the type
specimen from Tangancicuaro had six or seven pale cross-bands on the
anterior part of the body. An illustration, presumably of the same
specimen, by Duges (1884:Pl. 9) shows five distinct and one indistinct
cross-bands. Of the four specimens that I have examined, none has more
than three pale cross-bands, and one has only one indistinct cross-band.
Two females have 154 and 158 ventrals and 38 and 37 caudals; two males
have 150 and 151 ventrals and 43 and 42 caudals.

This species is known only from elevations between 1750 and 2050 meters
on the southwestern edge of the Mexican Plateau in the state of
Michoacan.

~Geophis incomptus~ Duellman

_Geophis incomptus_ Duellman, Occ. Pap. Mus. Zool. Univ.
Michigan, 605:3, May 29, 1959.--Dos Aguas, Michoacan,
Mexico.

Dos Aguas (15).

This species, which seems to be related to _Geophis maculiferus_, is
known only from the pine-oak forest in the vicinity of Dos Aguas
(elevation 2100 meters) in the Sierra de Coalcoman. Aside from the five
specimens comprising the type series, there are ten other specimens in
the Museum of Zoology at the University of Michigan collected by Floyd
L. Downs in July, 1960. Data from these specimens and those comprising
the type series show that in this sample seven males have 146-153
(149.3) ventrals and 35-37 (36.0) caudals; eight females have 150-154
(152.4) ventrals and 29-34 (32.5) caudals. The largest specimen is a
female with a body length of 344 mm. and a tail length of 53 mm.

Tzitzio.

The type and only known specimen of _Geophis maculiferus_ (UIMNH 25078)
is a female having 140 ventrals and 30 caudals, dorsal scales in 15
rows, one postocular, and an anterior temporal. Only one other species
in Mexico has dorsal scales in 15 rows and has an an
