[ 163 ] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 
The color is peculiar: it consists, on the body, in alcoholic specimens, 
of dark purplish chromatophores, everywhere pretty uniformly and 
regularly scattered, on a pale ground-color. When expanded these 
chromatophores are large and round; above the eyes they are so closely 
crowded as to form dark blotches; they also cover the outer surface of 
all the arms; underside of caudal fiu white. 
In alcohol, a medium-sized specimen measures from tip of tail to base 
of dorsal arms, S0 mm ; total length of mantle, 71 mm ; breadth of body, 
22 mm ; breadth of caudal fin, 52 mm ; length of fin, 39 mm ; length of dorsal 
arms, from base, 17 mm ; of second pair, 23 mm ; of third pair, 31 mIU ; of 
ventral arms 31 ,nm ; of tentacular arms, 4G mm ; of club, 22 mm . 
A larger female specimen, from Charlotte Harbor, Florida, measured, 
in length of mantle, 130 mIU ; diameter of body, 36 mm ; length of dorsal 
arms, 45 mm ; of second pair, 55 mm ; of third pair, 65 mm ; of tentacular 
arms, 145 mm . 
This species appears to have an extensive distribution along the 
warmer parts of the Atlantic coasts of America. It was originally 
described by Blainville as from Brazil. D’Orbigny records it from Bio 
Janeiro. It ranges northward to Delaware Bay. It is common on our 
southern coasts, from South Carolina to Florida, and I have seen speci¬ 
mens from Mobile Bay, Alabama, and from Louisiana.

SEPIOTEUTHIS Blainv., 1823. 
This genus closely resembles Loligo , in external characters. It is 
distinguished chiefly by having the fins extending nearly the whole 
length of the mantle. The body is stout and depressed, somewhat as 
in Sepia. The pen is thin and horny, lanceolate, nearly as in Loligo , 
but is often thickened near the margins. 
There are, however, important differences in the visceral anatomy. 
The eggs are much larger and fewer than in Loligo, and the ovary is 
short and broad, at the posterior end of the body.
