Thorius dubitus TayLor, Univ. Kansas Sci. Bull., vol. 27, pt. 1, No. 7, 1941d, pp. 
108-110, pl. 3, fig. 3 (Acultzingo, Veracruz). 
A series of 54 topotypic specimens was collected on August 19, 1939. 
Of these 27 were in Taylor’s hands when the species was described and 
are paratypes. These alone are cataloged and bear U.S.N.M. Nos. 
110984—110991, 1109938-111011. These specimens were collected in 
moss and among the roots of plants growing on the surface and form- 
ing a heavy mat. They are from very near the top of the ridge to the 
southwest of Acultzingo, Veracruz. One of the series (U.S.N.M. No. 
111011) was collected within the boundary of the state of Puebla near 
Pajaro Verde. 
The curious habit of this form, of coiling its body in a watch-spring 
spiral, was observed in almost every specimen encountered.

In all, 320 specimens were secured from the following localities 
(only a part of the series has been cataloged and now bears the fol- 
lowing numbers): Distrito Frprrau: Valle Alegre, July 23, 1939 
(U.S.N.M. No. 117397); Desierto de los Leones, June 16, 1940 (U.S. 
N.M. No. 117398). Mz#xico: Lake Zempoala, February 21-22 and 
August 25, 1939, July 28, 1940 (U.S.N.M. Nos. 116267-116277); 
Llano Grande, August 21, 1939 (U.'S.N.M. Nos. 116252-116261); 
Mount Popocatepetl, September 7 and October 8, 1939 (U.S.N.M. 
Nos. 116237-116251). Pumsua: 2 miles east of Rio Frio, México, 
August 26, 1939 (U.S.N.M. Nos. 116262-116266). Veracruz: Cruz 
Blanca, March 24, 1940 (U.S.N.M. Nos. 117390-117396); 17 km. 
northeast of El Limén, Totalco, March 23, 1940 (U.S.N.M. Nos. 
117383—-117389). 
One of us (Taylor, 1939a, pp. 280-283) formerly regarded oriza- 
bensis as a species separable from leprosa. Examination of large 
series of specimens (EK. H. T.-H. M.S. collection) shows that the pre- 
sumed specific characters originally observed break down in large 
series and were perhaps chiefly due to age and sex. We now regard it 
a synonym of leprosa. 
This species and B. chiroptera are the two commonest salamanders 
of the high plateau region of México. They are found in identical 
habitats.
