AnimaL corpulent, head and neck thick and clumsy, body poste- 
riorly flattened, and broadly rounded. Surface somewhat ocellate, 
with ranges of white granular papille, uniformly distributed. Dark 
fawn-coloured. 
Inhabits the Feejee Islands. 
The peculiar flattened and rounded posterior termination of the 
body, in the two last species, instead of the usual attenuated form,
