This species possesses the delicate and fragile appearance of 
a pelagic organism, and is so transparent that the venous system 
can be distinctly traced, without a lens, all about the head and 
up each arm. The body is soft and elongate, and the head is 
occupied by large prominent eyes. The arms are two and a half 
times the length of the body, and have small but very prominent 
suckers placed rather far apart ; none are specially enlarged. The 
hyaline umbrella attains more than one-third of the length of the 
arms, continues a little on their outer margins, and is slightly less 
between the ventral pair. Berry describes the umbrella as ex- 
tending about equally between all the arms for ‘‘ perhapsa twelfth 
of their length”’ His specimens were, however, all taken from 
the stomach of a salmon and it seems reasonable to suppose that 
the fragile membrane constituting the umbrella might easily 
suffer injury under such conditions. The mantle opens just below 
the eye. The funnel has an unusually broad apex, and the funnel 
organ is so peculiar that two specimens were examined, and both 
were found to agree exactly. The median organ consists of two 
very small, oblong, widely-spaced pads, placed rather near the 
anterior margin of the funnel, and single lateral pads of similar 
shape and size are also present. In the smallest specimen the 
median pads measure about 1'50 mm. in length, and the space 
between them is About 3 mm. Owing to the condition of Berry’s 
specimens, he was unable to give a, drawing of the funnel organs 
which is therefore given here (pl. xxiii, fig. 8). The hectocotylus 
(not observed in the type) is also figured (pl. xxiii, fig. 7). The ter- 
minal organ is small, and the usual transverse furrows are faintly 
marked in the largest specimen, and almost invisible in the others ;
