For many years this unusual salamander was known from only a few
specimens mostly collected in the last century; Smith and Taylor
(1948:7) stated: "It is presumed that this species is extinct owing to
the introduction of exotic game and food fishes." In 1951 and in 1955 I
had been told that _axolotls_ were sold in the market at Patzcuaro;
nevertheless, none was found on my visits there. In 1956 Charles M.
Bogert obtained several large specimens at the market in Patzcuaro.
These establish the continued existence of the salamander in Lago de
Patzcuaro. On January 27, 1955, R. W. Dickerman procured a specimen (KU
41573) in the market at Morelia. Since fish are brought to Morelia from
Lago de Patzcuaro, the specimen probably was from that lake.
Nevertheless, the species may occur in other permanent bodies of water
in Michoacan. Maldonado-Koerdell (1948) described _Bathysiredon dumerili
queretarensis_ from San Juan del Rio, Queretaro. This locality is about
200 airline kilometers northeast of Lago de Patzcuaro and is in the Rio
Moctezuma drainage.

~Ambystoma ordinarium~ Taylor

_Ambystoma ordinaria_ Taylor, Univ. Kansas Sci. Bull.,
26:422, November 27, 1940.--Four miles west of El Mirador,
near Puerto Hondo, Michoacan, Mexico.

Axolotl (56); Cerro San Andres; 22 km. W of Mil Cumbres; 46
km. E of Morelia (34); 8 km. SE of Opopeo (5); Puerto de
Garnica (8); Puerto Hondo (41); San Gregorio (16); San Jose
de la Cumbre (20).

Of 16 specimens (KU 51520-35) collected on June 18, 1955, near San
Gregorio, 15 are adult females with swollen cloacae and minute ovarian
eggs. Possibly these specimens had just recently deposited their mature
eggs. In preservative the specimens are black above and dull creamy gray
below. Measurements for the 15 females are: snout-vent length,
80.0-102.0 (92.5); tail length, 69.0-93.0 (84.2); head width, 15.8-20.5
(17.7); head length, 22.8-26.6 (24.4). A larval specimen with small
gills has a snout-vent length of 72 mm. and a tail length of 62 mm.
Three specimens have 12 costal grooves; the other have 11.

Of 20 specimens from San Jose de la Cumbre (UMMZ 112857 and 115143), 14
are neotenic adul
