 gera, we think, however, that it will be distin- 

 guished by the chjiracters given above ; its epidermis 

 is very black, and its inner lip of a fine orange co- 

 lour. All the specimens in thi» collection are rather 

 smaller than the full grown N.pulligeraE. From the 

 Islands of the South Seas.

 series ordinatis ; labii externi m.argine erenulato;

 aco, margine interno sinuato, edentulo.

 ral specimens in the collection, all of which have

 stance it is supposed that they have served as orna- 

 ments.
