4 NEW-YORK FAUNA — MOLLUSCA. 
tracted, and the water forcibly ejected so as to propel them backward with great rapidity, 
shooting like arrows through the water. They devour great numbers of small fish and crabs. 
The species above described is the only one I have noticed on the coast of New-York, 
although I think it highly probable that the six following, described in detail by Lesueur, will 
also at no distant day be detected on our coast. The plate referred to for the punctata, con- 
tains a figure of the cartilaginous, or rather membranous internal support; a figure of the 
oral apparatus (fig. 3); and a bunch of the egg-cases, or sea-grapes, as they are termed in 
Europe, with an embryo of a sepia highly magnified. This congeries I found on the northern 
shores of Long island.

suckers on the long arms,
