The collection of which the following is an account is chiefly of 

 interest because of the care with which most of the specimens have 

 been labelled, and from the fact that the supposed dry- and wet- 

 season forms of some of the species were both secured. There are 

 also several forms which are by no means common in collections, 

 and an interesting extreme form oi Almm nyassce, var. ochracea, 



1 Ehinococcyx, Cucuhis, Saurothera. In Eudynamis, Guira, and Biplopterus 

 there is a notch nearly converted into a foramen.
