REPORT OF COMMISSIONER OF FISH AND FISHERIES. [66] 
found three specimens thrown upon the beach, April 26 and May 8, 
1872. He made descriptions, measurements, and some very valuable 
drawings of them, while fresh. The specimens had all been more or less 
mutilated by the ravens before they were discovered. He preserved the 
pharynx, beak, and odontophore of No. 1, part of the ‘bone,’ a piece 
of the caudal fin, and the basal part of one of the ventral arms, with five 
of the suckers adhering, from one of the other specimens (No. 2), and 
has generously placed them in my hands for examination, together with 
his drawings, measurements, and. notes. 
The parts remaining of the largest specimen (No. 3) when found had 
a total length of 427°" (14 feet), but the ends of the tentacular arms had 
been destroyed; length from tail to base of tentacular arms, 559™ (8 
feet, 6 inches); to front edge of mantle, 232.4" (7 feet, 74 inches); width 
across fins, 107°" (42 inches); diameter of body, 45.7’ (18 inches); slen- 
der basal portion remaining of tentacular arms, 155°" (61 inches); their 
diameter, 6.3 (2.5 inches); short arms (ends gone), 76°" to 102 ° (30 
to 40 inches); length of pen, 226 (7 feet, 5 inches). 
_ According to Mr. Dall’s note the color was reddish, in fine red dots 
on a whitish ground, with a darker stripe on the outer median line of 
the arms. The eyes were bluish black, furnished with lids, and with a 
small sinus in front; diameter of the opening, 2.5°" (1 inch). 
The mandibles retracted into a short, yellow, puckered muzzle, 
which was included in a longer, plain, proboscis-like tube, extending 
an inch or two beyond. Siphon, short and thick.* Region of the eye 
somewhat raised, The nuchal collar is well marked, and slightly above 
it, on each side, is a raised epidermal ridge, from which three wavy 
raised crests or frills, attached at their inner edge, pass obliquely back- 
ward, on each side. No cranial cartilage was observed. Mantle firm 
and dense. The neck has one median dorsal and two ventral facets, 
long, oval-shaped, with a median depressed line, but otherwise smooth 
and white; the dorsal moves on a smooth part of the inside of the man- 
tle; the ventrals move on similar raised facets of the mantle beneath. 
The caudal fin was rather broad, lanceolate or spear-shaped, acute at 
tip. Gills yellowish olive, with obliquely transverse laminze. Gizzard 
yellowish, the muscles laid like a coil of spun-yarn, in layers transverse 
to one another. 
The pen (Plate XIII, figs. 4, 5) was gone from the first specimen 
(No. 1) and broken in the others. It was found unattached in the dor- 
sal cavity. It had a thickened median rib, but becomes very thin at 
the sides, and is divided by sharp, stiff ribs or folds into three longi- 
tudinal areas on each side (Plate XIII, fig. 6). The posterior end is 
one-sided, funnel-shaped close to the tip, which is inserted into a long, 
round, thick, firm, cartilaginous cone, which tapers to a point posteri- 
*No valve is shown in Mr. Dall’s sketches.
