two specimens is practically immaculate; in the others it is covered 

 with small dark spots or suffused dark areas. 



One of the Valle Nuevo frogs has a wide white dorsal stripe; another 

 has a wide pale lateral stripe with dark dots above and below it. Most 

 of these still have a vinaceous tone in the dorsal coloring, showing that 

 they must have been pinkish in life. 



Relationships. — It seems apparent that this new form is intermediate 

 between Eleutherodactylus audanti Cochran and E. minutus Noble. 

 The vomerine teeth of intermedium and minutus are nearly identical. 

 The teeth of audanti are much weaker, although in color pattern and 

 in leg proportion it is quite close to intermedius. The last-named 

 has a shorter snout than either of its allies, and seems to deserve 

 specific recognition. 



In order to allow still further comparisons to be made, a list of meas- 

 urements of some of the paratypes of intermedius is given in table 14.

Original description. — "Type. — Museum of Comparative Zoology, 

 no. 21,561, apparently a male, from northern and eastern foot-hills, 

 Massif de la Hotte, 1000-4000 ft., Haiti, collected by P. J. Darlington 

 in October, 1934. 



"Diagnosis. — Possibly most closely related to Eleutherodactylus 

 montanus, from which it differs in shape of head, in possessing larger 

 digital disks, more extensively webbed toes, and in coloration. 



"Description. — Tongue suboval, very slightly nicked behind; 

 vomerine teeth in two oblique groups behind and between the choanae; 

 snout obtuse, longer than the diameter of the eye; can thus rostralis 

 distinct, straight; loreal region concave, almost vertical; nostril
