CYMBIUM. 
Puate XV. 
Species 7. (Fig. 6, Mus. Cuming; Fig. c, Mus. Brit.) , from Mr. Cuming’s collection, the colour is a rich ciina- 
| mon-brown or chestnut, conspicuously two-banded, and the 
interspaces merely show a somewhat sparse and irregular 
mottling of white. The specimen Fig. 7c, from the British 
Museum, is of a more squarely stunted form, less darkly 
coloured. 
The specimens here figured of C. diadema represent the 
more squarely ovate form of the species, with the scales 
of the corona shorter, and they are distinguished by a 
more densely clouded painting. In the specimen Fig. 7 0, 
February, 1861.
