A. E. Verrill — North, American Cephalopods.

Sandy Bay, Mass. (Lesueur). Newfoundland (Steenstrup). Off 
Madeira (D’Orbigny). 
No instance of the occurrence of this oceanic species on the New 
England coast has been recorded since the original specimen was 
described by Lesueur, in 1821. The circumstances connected wdth 
the history 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 : 
“ 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 surprised to perceive that I had brought 
with me a very distinct species from that which I had observed [ 0. 
illecehrosus]. I mention this circumstance to explain the cause of the 
brevity of the following description [of O. illecehrosus ] taken from 
my drawing.” The drawing w r as also inaccurate, for the same reason.

Body more or less elongated, tapering to a point behind ; anterior

dorsal and two lateral connective cartilages ; lateral cartilages of the 
mantle simple, longitudinal ridges ; corresponding cartilages, on the 
base of the siphon, irregularly ovate, with a median groove. Pen 
as long as the mantle, anteriorly narrow, with a central keel, and 
two lateral ridges ; posteriorly broad, thin, lanceolate, concave, but 
not involute. Head rather large ; eyes without lids, covered with 
transparent skin, pupil encroached upon dorsally by the iris ; a small 
pore in front of the eyes; behind the eyes, on each side, there is an 
oblique transverse, and two longitudinal, erect, thin crests, in rela- 
tion with the ears. Siphon situated in a shallow groove, united to 
the head by two dorsal bridles, and furnished with an internal valve.
