In the southern part of México and to some extent in Central 
America the species is replaced by Bolitoglossa mexicana. 
The Hidalgo specimen was found under a stone on the ground in a 
small grassy meadow at an elevation of about 3,000 feet, probably 
at nearly the maximum elevation attained by the species in that area. 
All San Luis Potosi specimens were found in bromelias, at a much 
lower elevation (about 300 feet above sea level). For other comments 
on habitat see the discussion of B. rufescens.

Seventy-four specimens were secured; the following are numbered 
in the Museum collection: U.S.N.M. No. 116070 from Piedras Negras, 
Guatemala, May 24, 1939; U.S.N.M. Nos. 116071-116098 from San 
Juanito (near Palenque), Chiapas, July 7 to 23,1939. All were found 
in large arboreal bromelias. 
Variation in color and pattern is considerable. The belly is nearly 
black in some specimens, dark brown in others, but in four it is light 
gray. Intermediate shades are present. In all specimens there are 
observable at least a few white flecks or short streaks on the ventral 
surfaces; in some the flecks are very few, in others they are numerous. 
The dorsal light color varies from orange to pale yellow; many speci- 
mens show some reddish tinge. 
The sides of the body are black or dark brown, even in the lighter- 
bellied specimens. The dark lateral color terminates in the dorso- 
lateral region, on a line extending from the upper eyelid along the 
sides of the body above arm and hindleg onto tail. At this line the 
dorsal color begins, sharply defined from the lateral dark color. The
