gressioii, especially swimming, — further the copulation and reproduction of 
the first species. The arms of both individuals are so narrowly interlaced 
during copulation, that the jaws are in contact, and at the same time the 
pupils are so extended as to appear circular. Males and females of Sepia are 
not to he distinguished externally by any striking difference in form or colour.

This species occurred in great abundance at Nahant during the summer of 
1863. They come to the surface of the water about an hour after dusk, and 
do not remain long \ after ten o’clock at night they were rarely met with j 
they can creep about by means of their wing-like appendages, and remain 
suspended in the water for hours simply by spreading, and suddenly drop 
to the bottom on folding them: they move by beating the water like a 
butterfly ; and a long siphon counterbalances the weight of the shell and the 
parts enclosed in it.
