Hylella puncticrus, Bouleng. Ann. & Mag. N. H. 1896, xviti. p. 341. 
Hab. Costa Rica, Limon (Fleischmann), La Palma (Underwood); Panama, Bugaba 
(Champion). 
Vomerine teeth (if present) in two transverse series, between the choane. Head 
broad, depressed, with very short snout, and with large eyes, directed forwards; canthus 
obtuse, concave, sides of the snout sloping. Diameter of the eye a little more than its 
distance from the nostril, and much more than the distance between the nostrils; 
upper eyelid narrow, narrower than the interorbital space. Tympanum very small, 
deeply sunk, about one-sixth the area of the eye. The two outer fingers one-third 
webbed, but the third and second are connected only by a rudiment of a web; toes 
four-fifths webbed. The disks of the fingers are larger than those of the toes and 
than the tympanum. When carried forwards, the heel reaches beyond the end of the 
snout. Upper parts smooth, abdomen coarsely areolated. Light purplish above with 
scattered round dark purple or blackish dots; lower parts whitish ; the concealed parts 
of the limbs not pigmented, the remainder coloured like the back. Humerus of the 
male with a projecting, curved, compressed osseous process.

A small species, in which the vomerine teeth appear to be as frequently absent as 
present ; specimens with and without them occur in the same locality.

Hab. Panama, Chiriqui. 
Vomerine teeth in two groups between the choane, which are much wider than the 
narrow eustachian ostia. Snout as long as the eye, with obtuse canthus. Tympanum 
very small and covered with pigmented skin. The three outer fingers broadly webbed, 
the web extending to the disks of the second and fourth fingers, but not to that of the 
third; toes broadly webbed. Upper parts smooth, abdomen granulated; no fold above 
the tympanum. Colourless, with scattered white points. (After Peters.)
