teriorly. The caudal fin is long-cordate, but not slender-pointed. The 
pen is lance-shaped, the anterior portion being long, narrow, of nearly 
uniform width; posterior end broad-lanceolate, short-pointed posteriorly, 
and, according to the figures, without a cone at the tip. The anterior 
dorsal edge of the mantle is represented as free externally, but there is 
a dorsal commissure within the mantle-cavity, and a lateral one on each 
side. Arms short, subequal; suckers flat, denticulate, those of the 
tentacles with sharp, incurved teeth. Eyes large, globular, prominent; 
lids free and simple. 
Siphon with neither valve nor dorsal bridle. No external ears, nuchal 
crests, nor cephalic aquiferous pores.

This species differs externally from the preceding in having a much 
shorter, obtuse, oblong-cordate fin, instead of a long, slender, pointed 
one, and by its very distinct coloration. According to Lesueur, the 
general color is carmine-brown, the mantle, head, and arms “ covered 
on every part with very large ocellations, which are connected together 
by smaller intermediate ones.” Length of mantle, 10 inches.

No instance of the occurrence of this oceanic species on the New 
England coast has been recorded since the original specimen was de¬ 
scribed by Lesueur in 1821. The circumstances connected with the his¬ 
tory of his specimen are such as to render it not improbable that some 
interchange of labels had occurred in his case. Therefore, the New 
England habitat for this species needs confirmation. 
Lesueur’s statement (loc. cit., p. 94) is that when at Sandy Bay, Mass, 
(on Cape Ann), in 1816, he saw a “great number” of squids (“ Loligos ”) 
that had been taken by the fishermen for bait, and that u the beautiful 
color with which they were ornamented induced me to take a drawing 
of one immediately, but not then having leisure to complete it, I took a 
specimen with me to finish the drawing at my leisure. But recently [in 
1821], upon comparing this specimen with my drawing, I was much sur¬ 
prised to perceive that I had brought with me a very distinct species 
from that which I had observed [O. illecebrosus]. I mention this circum-
