A, E. Verrill — North American Cephalopoda. 
not be seen with the naked eye ; they are deep, cup-shaped, with a 
small circular aperture, supported by a horny rim, which is often 
armed with two or three sharp teeth on one side (fig. 3e). 
Color of body and arms, so far as preserved, in alcohol, deep 
brownish orange ; on the upper side of the back and caudal fin the 
color is better preserved, and shows small, ocellated, circular spots of 
orange-brown, with an inner circle of whitish, and a central spot of 
purplish brown. Similar spots also exist on the head and arms, and 
also on the lower side of the body, where the color is best preserved. 
A considerable amount of a bright orange oily fluid, insoluble in 
alcohol, exuded from the viscera. Examined by means of the spectro- 
scope this fluid absorbed part of the green, all of the blue, and most 
of the violet rays. The stomach contained fragments of small Crus- 
tacea. The pen is pale yellow, thin, and slender anteriorly, with two 
sublateral costae, and narrow delicate margins outside the costae ; in 
the middle it becomes still thinner and narrower, with the margin 
inrolled; beyond, the margins become much wider and then unite 
together ventrally, forming a long, hollow, conical portion, extend- 
ing to the acute posterior tip ; this portion is not so broad as deep, 
and has a slight dorsal keel and ventral groove.
