Mr. Westwood exhibited several new and remarkable species of 
beetles belonging to the families Cicindelide and Carabide. The 
species of the former family belonged to the genera Collyris and 
Tricondyla, peculiar to the islands of the Eastern Ocean, and had 
been collected by the late Colonel Champion and by Dr. Templeton 
in Ceylon. The species of Carabide were remarkable for having 
the antenne particoloured, several of the joints being white. They 
were collected in Ceylon by Mr. Thwaites, in India by General Hear- 
sey, in Brazil by Mr. Bates, and formed several new and distinct 
genera.

Genus Crea, H. and A. Adams. 
The shell on which this genus is founded resembles a fluviatile 
Buccinum, and is from the river in Sarawak Borneo. The notch at 
the fore part of the aperture differs from that of Melanopsis, and the 
form and abruptly truncate columella separates it from Hemisimis of 
Swainson. The only species at present known is that described 
below, distinct varieties of which have lately been received from 
Malacca.
