^fr. G. A. Boulenfrer on new 



jircyisli-wliite, davk-edged streak on each side of the back, 

 beginning behind the uj)j)er eyelid and converging towards 

 its fellow on the scapular region ; a greyish streak round the 

 snout, above the canthi, and a broader band of the same 

 colour, forming a very open chevron, across the interorbital 

 region ; limbs with ill-defined dark cross-bars ; sides of head, 

 bod}', and limbs with white dots; lower parts white, throat 

 brown. Male with a subgular vocal sac. 



From snout to vent 21 mm. 



A single specimen from Zima. 



The extraordinary elongation of the third finger I have 

 ascertained to be a character of tiie males in the species of 

 Cardioglossa, BIgr., and in Arthroleptis variabilis, Matsch., 

 and A. poecilonotus, Peters, with which 1 now regard 

 A, macrodactijlus, Blgr.*, A. bivittatus, F. Miill. (both males), 

 and A. inguinaUs, Blgr. (female), as specifically identical. 

 For the same reason I now hold A. Seimundi, Blgr., to be the 

 male of A. variabilis. In well-preserved specimens, the inner 

 side of the second and third fingers of these males may be 

 seen to be furnished witii a fine serrature of tooth-like, trans- 

 lucid granules, differing from any of the nuptial excrescences 

 v,\\\\ which I am acquainted in 13atrachians.

The species described under the name of Arthrolejytis are 

 much in want of revision. I may here note that A. sechel- 

 lensis, Boettger, differs in the entire, elliptical tongue, and 



* The figure of the type (Cat. Batr. Ecaud. pi. xi. fig. 5) is taken 

 from a badly preserved specimen, and very inaccurate as regards the 

 shape of the snout.
