MEXICAN AMPHIBIANS—TAYLOR AND SMITH 567 
ELEUTHERODACTYLUS CONSPICUUS, new species 
FicurRE 60, A 
Type.—U.S.N.M. No. 116509, collected at Piedras Negras, Guate- 
mala, near the México-Guatemala border, by Dr. and Mrs. Hobart 
M. Smith, May 29, 1939. 
Paratypes.—U.S.N.M. Nos. 116506-116508, 116510-116511, and 
E.H.T.-H.M.S.No. 29807. ‘Topotypes. Same collectors, May 24 to 
June 10, 1939. 
Diagnosis.—Related to Hleutherodactylus alfred: and, like that form, 
lacking a vocal sac and having the tips of the digits strongly dilated. 
Differing from alfred: in lacking a tarsal fold, in having shorter hindlegs 
with the tibiotarsal articulation reaching only to the nostril instead of 
beyond the snout tip; the vomerine teeth barely reach the posterior 
level of the choanae, instead of to the middle of the choanae. The 
color and markings are different. 
Description of the type.—Adult female. Head length (18 mm.) a 
little greater than width (16.5 mm.); width of an eyelid a little less 
than the interorbital width, which is in turn one-fourth greater than 
the distance between the nostrils, and about two-thirds the distance 
between eye and nostril; diameter of the tympanum (2.8 mm.) a little 
more than half the diameter of eye (5 mm.); canthus rostralis rounded 
but more or less distinct, the lores concave, then sloping very obliquely 
to the edge of lip; areas about nostrils slightly elevated, with a visible 
depression between them on top of snout. Choanae large, but 
smaller than area of a group of vomerine teeth, which barely reach the 
posterior level of choanae, anteriorly; tooth groups separated by a 
distance equal to about half width of a single group; tongue subcircular, 
free posteriorly for about one-fourth its length, not emarginate behind. 
(Vocal sac absent in males.) 
Arm moderate in length; the first finger shorter than the second; the 
disks unequal, with strong transverse grooves; the disks of at least the 
two outer fingers emarginate (somewhat bilobed) medially; diameter of 
disk on third finger (2.4 mm.) a little less than the diameter of tympa- 
num; no trace of a web, but lateral edges of fingers with a trace of a 
ridge; three palmar tubercles, the outer partly confluent with the very 
large median tubercle; a few supernumerary tubercles on the palm; 
heels overlap about 1.5 mm.; the tibiotarsal joint reaches to the nostril; 
toe disks dilated, smaller than those of the fingers, the three outer 
disks somewhat emarginate; a large, elongate, somewhat compressed 
inner metatarsal tubercle; outer metatarsal tubercle small, round; 
three supernumerary tubercles on the sole; tarsal fold absent (a fairly 
strong tarsal fold in alfred) ; third and fifth toes equal; fourth relatively 
short.
