This curious Toad was described from young specimens collected 

 by Sir H. H. Johnston in the Kio del Eey district, Camaroons. 

 Adult specimens have been redescribed by Werner under the 

 name of B. lavissimus, from Camaroons. A young specimen is in 

 Mr. Bates's collection from the Benito Biver. I have also 

 examined a fine specimen, measuring about 120 mihim. from 

 snout to vent, from the Congo Free State.

I have recently described this Toad from a single specimen from 

 the Benito Eiver, collected by Mr. Bates. I have now examined 

 several specimens, and have to add that the tarso-metatarsal arti- 

 culation may fail to reach beyond the anterior border of the eye, 

 that the toes are one-third webbed in breeding specimens, that the 

 parotoid glands may be more distinct than in the type specimen, 

 narrow and shorter than the head, and that the male is provided 

 with an internal subgular vocal sac and brown nuptial asperities 

 on the inner side of the two inner fingers. Limbs with dark 

 cross-bars. The largest male measures 30 millim. from snout to 

 vent, the largest female 40. 



10. Nectophrtne afra Ptrs. 



Originally described from Camaroons. Two specimens ( c? $ ) 

 are in Mr. Bates's collection from the Benito Biver.

The subarticular tubercles of the fingers and of the toes are 

 much developed, and flattened into overlapping pads which bear a
