In view of this record involving a westward extension of the range 

 of nearly a thousand miles, one might have supposed that they would 

 represent a western race for they differ in several details from the 

 description. Their vomerine teeth are between (not behind the level 

 of) the choanae, though situated somewhat posteriorly; the head is 

 distinctly (not slightly) broader than long; the snout is two-thirds 

 (not equal to) the diameter of the eye; the interorbital space is broader 

 than (not as broad as) an upper eyelid; the tympanum is two-thirds 

 (not two-fifths) the diameter of the eye. 



In all these respects, however, they agree with a series (M.C.Z. Nos. 

 21681-8) of females and young from Djamba, Belgian Congo (det. de 

 Witte), and all with the striking color pattern as figured by 

 Boulenger. There is considerable variation in the amount of white 

 ( ? red, ? yellow) in the groin and elsewhere. These males exhibit the 

 black vocal sacs flanking the central gular disk which is common to 

 males of their allies of the genus Kassina. Boulenger gave 54 mm. as 

 the length, probably of his cotype 2 and not of the $ for the Bendaja 

 $ $ measure 45-47 mm.

Parker (1936c, p. 95) has cleared up the confusion that has long 

 centered about West African frogs of this group and referred hyloides 

 Boulenger, nanus Ahl, and togoensis Ahl to the synonymy. To these 

 I would now add liberiensis Ahl, described as having a very faint rudi- 

 ment of web between the fingers but in all other respects agreeing with 

 viridis^ which most authors agree to consider as having "fingers free." 

 Males are distinguishable by their dark throats. Length oi $ $ 30-34
