 it is absent in the female. The type of the species was from the Gaboon.

 in this region is therefore of interest.

Reptiles and Batrachians. — The Department of Reptiles and 

 Batracbians has received a number of specimens from the naturalists 

 attached to the expedition. Some of them were not in a satisfactory 

 state of preservation, and from the fact that the collection was made 

 under unfavorable circumstances, in localities already more or less ex- 

 plored, it could hardly be expected to contain many new species. 



Fishes. — The Department of Fishes received a large collection, a list 

 of the genera of which, together with the locality, is given below.
