is generally a light open chevron pointing forwards across the middle of 

 the back, with a dark one in front of it. In the largest specimen a pink 

 hand extends from the orbit posteriorly to the ilium. Posterior face of 

 femur brown with light specks or finely brown mottled. Other lower 

 surfaces -whitish, except that in a few specimens the gular region is 

 obscurely brown mottled. 



This species belongs to the short legged group represented by the L. 

 diastema, and need not therefore be compared with the L. podiciferus, 

 muricinus and rhodopis, where the heel reaches much beyond the muzzle. 

 From L. diastema it differs in the much longer posterior foot, and in the 

 close approximation of its teeth, which form a row and not a fascicle. 

 The tympanum is at all times much larger and more distinct, although 

 it is variable in diameter. 



This species is dedicated to Doctor John F. Bransford, U. S. N., whose 

 researches have thrown much light on the fauna of Nicaragua.

This form is a little nearer to some already known than the last de- 

 scribed. The heel of the extended hind leg reaches exactly the end of 

 the muzzle, being thus still shorter than in the group above mentioned, 

 which is represented by the L. rhodopis and its allies. The vomerine teeth, 

 unlike any of the forms mentioned, are in small fasciculi, which are not 

 widely separated, and which are entirely behind the line of the posterior 

 border of the nares, and within that of the internal border. A dis- 

 tinctive character is the presence of a small web between the toes, 

 which is nearly as well developed as in the Hylodes (Lihyla) guentherii 

 Keferst. The diameter of the tympanic disc is about half that of the 

 ball of the eye. The tongue is a parallelogrammic oval, and is entire 

 posteriorly. The head is relatively rather long, and the muzzle is 

 acuminate. The muzzle projects somewhat beyond the mouth, and be- 

 yond the nares, which are above the edge of the symphysis mandibuli. 

 Its length a little "exceeds that of the eyeball, which itself is more than 

 half larger than the interorbital width. The canthus rostralis is distinct 

 and nearly straight. The digital dilatations are truncate. The external 

 metatarsal tubercle is obsolete, and the internal one is small. The skin 

 is nearly smooth, but a pair of feeble folds form an obscure pattern on the 

 scapular regions.

Color dark ashen above, darker on the head. A pale cross-band across
