a large number of new species, of Sponges from the Caribbean 
Sea. External characters are to a very great extent selected as 
tliose diagnostic of the genera and species — characters which, 
however important they may be, are surely in this group but 
subsidiary. In several cases we have been quite unable to dis- 
cover what were the leading diagnostic marks ; indeed many of 
the genera can scarcely be said to be described. This is partly 
owing to the fact that no fixed scientific nomenclature has been 
adopted in this branch of descriptive zoology. The plates are 
for the greater part coloui*ed representations of living Sponges, 
and, for general effect, are the best we know of.
