the lips below nostrils in males, and a large single median curving 
tooth piercing the upper lip. A large female, measuring 21 mm. snout 
to vent, contained six eggs, three in each ovary. 
Of the three species of this genus occurring in the mountains in this 
part of Veracruz all have the chin more or less speckled with small 
cream spots. Only pennatulus has the underside of the body, and to 
some extent the sides, so marked. 
THORIUS NARISOVALIS Taylor _ 
Thorius narisovalis TAyLoR, Univ. Kansas Sci. Bull., vol. 26, No. 12, 1939 (Nov. 
27, 1940f), pp. 416-418, pl. 47, fig. 3 (Cerro San Felipe, Oaxaca). 
Two topotypic specimens from the Cerro San Felipe, Oaxaca, col- 
lected Juiy 10-20, 1940, are U.S.N.M. Nos. 116454, 116455. This 
form occurs on Cerro San Felipe at a considerably higher elevation 
than Thorius pulmonaris. ‘The latter species is terrestrial, invariably 
found in masses of wet leaves; 7. narisovalis on the other hand was 
almost invariably found under logs or the loosened bark of logs. 
When uncovered they usually made prodigious leaps. 
The specimen in the National Museum from Cerro San Felipe, 
Oaxaca (U.S.N.M. No. 47608), referred by Dunn (1926, p. 376) to 
Oedipus pennatulus, belongs to T. narisovalis. 
THORIUS PULMONARIS Taylor 
Thorius pulmonaris TAYLorR, Univ. Kansas Sci. Bull., vol. 26, No. 12, 1939 (Nov. 
27, 1940f), pp. 411-414, figs. 3-4 (Cerro San Felipe, Oaxaca). 
Three topotypic specimens, U.S.N.M. Nos. 116451-116453, are in 
the collection from Cerro San Felipe, near Oaxaca, Oaxaca, collected 
July 10-20, 1940. The elongate-oval nostril, diagonally placed, 
easily distinguishes this form from other members of the genus. 
The specimen (U.S.N.M. No. 47797) from Reyes, Oaxaca, re- 
ferred by Dunn (1926, p. 376) to Oedipus pennatulus, belongs to 
T. pulmonaris.

Thorius troglodytes TaAyLor, Univ. Kansas Sci. Bull., vol. 27, pt. 1, No. 7, 1941d, 
pp. 110-112, pl. 3, fig. 4 (Acultzingo, Veracruz). 
Thirty-three specimens were collected. Cataloged are 16 topo- 
typic paratypes, from near Acultzingo (U.S.N.M. Nos. 110969— 
110983, 110992), collected January 15-18 and August 19, 1939; 9 
others are practically topotypes, but were collected a kilometer or two 
(straight line) away, within the boundary of the state of Puebla, near a 
spot named Pajaro Verde (U.S.N.M. Nos. 110960-8), in January and 
December 1939. They were obtained from under rocks, chip piles, 
and moist leaves.
