a species of the Mediterranean — M. amethystmo-pzmctalus — is 
said to be “extremely similar to our recognised species, but 
with the body comparatively shorter and the head longer;” a 
character which raises the question whether it may not be the 
one of which we have given the figure. There are two other 
species known in the same sea, of which an important character 
is said to be that the bright dots along the belly are each 
one placed on a black globular body.
