Atzimba (3); Macho de Agua (9); Puerto Lengua de Vaca (14).

Previously this species has been recorded only from the type locality.
In July, 1956, individuals referable to this species were found at two
sites in pine-fir forest immediately to the east of Macho de Agua and in
pine-oak-fir forest at Atzimba. On August 20, 1958, a series was
collected in pine-fir forest at Puerto Lengua de Vaca. These localities
are between 2900 and 3000 meters in the Cordillera Volcanica in eastern
Michoacan.

In life the coloration of these salamanders was highly variable. The
belly and undersurfaces of the tail and hind limbs were pale gray, with
or without silvery white flecks; the chin was a cream-color and flecked
with silvery white in some specimens. The middorsal area was brown,
orange-brown, or dull grayish yellow. The flanks and lateral surfaces of
the tail were black with yellowish flecks or streaks on the flanks and
yellowish or orange-brown flecks on the tail. The iris was golden brown.
Measurements of eight males and two females are, respectively:
snout-vent length, 42.5-56.0 (49.5), 54.0-60.0 (57.0); tail length,
42.0-56.0 (48.1), 52.0-55.0 (53.5). The smallest juvenile has a
snout-vent length of 28.0 mm. and a tail length of 23.0 mm. Of the 26
available specimens, six have 12 costal grooves, and the others have 11.

In comparison with 36 topotypes, the specimens from Michoacan have a
less striking dorsal color pattern; none has a well-defined dorsal
reddish brown area or bold reddish mottling on the tail. Furthermore,
the specimens from Michoacan have paler venters than do topotypic
specimens.

Mouth of the Rio Balsas (10).

These specimens (BMNH 1914.1.28.181-90) were collected by Gadow in 1908
and reported by him (1930:72): "Whilst this very sluggish termite-eating
toad is common enough in the sweltering hot country of the state of Vera
Cruz, up to an elevation of 1500 feet, it w
