I have long hesitated before I ventured to distinguish this frog under a distinct 
name; however, the receipt of a second specimen agreeing in every essential distinctive 
character with the first, removed every doubt about the species being distinct from 
L. fleischmanni. The male has the testicles well developed, yet lacks vocal sacs. 
These organs are present in much smaller specimens of L. fleischmanni. 
6. Liohyla engytympanum, sp.n. (Tab. LXV. fig. A.) 
Hab. Costa Rica, Monte Redondo (Underwood, in Mus. Brit.). 
In general habit and form of the head similar to LZ. rugulosa. Snout rather obtuse, 
with the canthus rostralis distinct, and with sloping sides; eye scarcely equal to its 
distance from the nostril. Zympanum an irregular oval, deeper than long, barely half 
the area of the orbit (in adult female). Vomerine teeth in two short prominent 
transverse series, slightly separated from each other, behind but within the level of the 
choane ; choanz rather wider than the eustachian openings. Upper and lateral parts 
of the body, supra-orbital region, and upper parts of the hind limbs with tubercles 
and granules ; a glandular fold above the tympanum ; abdomen smooth, with indistinct 
granules on the sides; transverse and longitudinal folds indicate the presence of an 
abdominal disk. Length of the body a little less than the distance between vent and 
heel. Disks of fingers and toes subequal, rounded, moderately developed ; first finger 
rather longer than the second; a rudimentary web between the three inner fingers. 
Metatarsals without pads, except at the base of the inner toe; outer metatarsal tubercle 
scarcely visible; a tarsal fold. Toes one-fourth webbed. Greyish, with a yellow 
vertebral and gular line; an indistinct dark interorbital cross-band. Upper lip and 
flanks with blackish spots. Upper parts of the limbs obscurely banded ; hind part of 
the femur rather finely and conspicuously marbled with black and white. Lower parts 
white.
