on the canthus rostralis , by the hidden tympanuin , and by the 

 extension of web ; but the snout is rather rounded , not truncate. 



Rappia nasuta Gthr, one specimen. Our specimen not only 

 possesses the small blackish dots on head and back, described by 

 Dr. Günther and Mr. Boulenger, but is moreover distinguished 

 by a light line , running along the canthus rostralis , the outer 

 margin of the superior eyelid and the side of the body, its ro- 

 stral portion being marked below by a dark line. These charac- 

 ters also belong to Rappia microps Gthr. On the upper eyelids 

 the minute dark dots have become confluent into dark spots. 



Hylambates Grêshojjii sp. n., one specimen. The vomerine teeth 

 extend in two small, rounded groups beyond the level of the 

 choanae. Tympanum about half the width of the eye, distinct. 



Three outer fingers webbed at 

 the base, toes nearly entirely 

 webbed ; the disks are well de- 

 veloped. Skin granular on the 

 belly and under the thighs. Ked- 

 dish brown above (in spirits) , 

 lighter beneath. 



I would not have ventured to 

 describethis new species without 

 having applied a crucial test to 

 its validity as such. For his kind- 

 ness in examining the specimen 

 and in looking at my MS. be- 

 fore it was prepared for the 

 press , I have to thank Mr. Boulenger , the assistant keeper of 

 this Department of the British Museum. 



Hemisus sudanense Stdchr., one specimen. 



JBufo regularis Heuss., two specimens. 



A. Lower surface of hand. 



B. Lower surface of foot.
