A single specimen of this species, U.S.N.M. No. 116382, is from 
Cerro San Felipe, Oaxaca, collected July 10-20, 1940, by E. H. Taylor. 
B. smithi superficially resembles B. unguidentis but may readily be 
separated by the character of the premaxillary teeth, and the longer 
body and shorter legs, which fail to touch by four costal grooves. 
There is also less webbing on the toes. The frontal bones bordering 
the frontoprefrontal fontanelle bend down and form sutures with 
the prevomers. 
To this species belong two specimens (U.S.N.M. Nos. 47606, 47607) 
from Cerro San Felipe, Oaxaca, previously referred (Dunn, 1926, 
pp. 364-366) to Oedipus sulcatus. 
BOLITOGLOSSA MELANOMOLGA Taylor 
Bolitoglossa melanomolga TAayuor, Proc. Biol. Soc. Washington, vol. 54, July 31, 
1941b, pp. 81-83 (20 km. north of San Antonio Limén [Totalco], Veracruz). 
Two paratypes, one a topotype from near Teziutlin (June 25, 1940) 
and one taken at a point 17 km. north of San Antonio Limén (March 
24, 1940), are in ‘the collection. These bear U.S.N.M. Nos. 110641 
and 110640, respectively. 
BOLITOGLOSSA UNGUIDENTIS Taylor 
Bolitoglossa unguidentis TayLor, Herpetologica, vol. 2, No. 8, March 25, 1941a, 
pp. 57-62, figs. 1-8 (Cerro San Felipe, Oaxaca, Oaxaca). 
One topotypic specimen, U.S.N.M. No. 116383, from Cerro San 
Felipe, Oaxaca, July 10-20, 1940, is in the collection. It is entirely 
typical. The curious bifid or hooked character of the premaxillary 
teeth of ungurdentis, melanomolga, smithi, and gadovii shows their very 
close relationship.
