mentioning, so that the formula is perhaps preferably stated as 3=4, 2, i. (3) The homy rings of the 
tentacular suckers have 12 to 14 instead of 10 teeth on the upper margin. These are none of them very 
great differences, but seem sufficient, together with the widely separate habitats of the two forms, to 
render their imion unjustifiable until a better representation of each is available for study. 
My original reference of this species to Helicocranchia was certainly ill advised, our species differing 
conspicuously in the larger, more elongate nonpedunculate fins, spitlike posterior continuation of the 
mantle, much smaller funnel, and very much larger unstalked eyes. 
The discovery of tliis species very greatly extends the known geographical range of the little group 
of typical Megalocranchia, but even yet the distribution of the various species is of interest because of 
the continuity of the respective regions occupied by them. Beginning 
with M. pellucida in the south Atlantic, the remaining species form a geo- 
graphic chain extending more than halfway around the globe. M. maxima 
is known only from the Cape of Good Hope, M. abyssicola Goodrich from 
the waters of the Indian peninsula, and the present species from the 
Hawaiian Islands. Because of its occupancy of so distant and isolated a 
region, the Hawaiian species might be expected to be the most highly 
differentiated member of the group, but such is very far from being the 
case. On the other hand M. abyssicola seems in many ways peculiar and 
not so closely allied to any of the other three forms as they are to one 
another. 
It has been a pleasure to associate with this interesting species the name 
of my friend. Dr. Walter K. Fisher, who, as a member of the staff of the 
Albatross during the Hawaiian explorations, had no small part in the 
duties of caring for and preserving the present material. 
Genus HELICOCRANCHIA Massy 1907. 
Helicocranchia'Massy 1907. p. 382- 
Helicocranchia Massy 1909, p. 34. 
Desmoteuthis (pars) Chun 1910, p. 302, 357. 
Teuihowenia {Helicocranchia) Pfeffer 1912, p. 742, 750. 
Body elongate, bag shaped. Fins small, oval; narrowed or even 
pedunculate at base; little or not at all united posteriorly. Eyes large, 
elevated on short stalks. Arms rather long, with two rows of suckers; no 
hooks. Funnel enormous, extending well past the head and eyes. 
Type. — Helicocranchia Pfefferi "Massy 1907 (monotypic); described from 
off the coast of Ireland. 
Chun has referred this genus to Desmoteuthis (i. e., Megalocranchia), 
but it seems to me to be rather nearer to Owenia {Teuihowenia Chun), 
from which it diSers most conspicuously in the more rounded eyes and 
enormous development of the funnel. 
Cranchiid species, Berry 1909, p. 419 (mere locality record). 
A single sadly dilapidated specimen of some cranchiid approaching very close to this genus was 
taken at Albatross station 4001, 230 to 277 fathoms, off Kapuai Point, Kauai [S. S. B. 261]. It is too 
fragmentary for satisfactory determination, but has been made the subject of the following notes; 
Mantle much wrinkled and distorted; its outline in general elongate, swollen, cask-shaped; tapering 
behind to a point; anterior margin fused with head in the nuchal region and on either side of the fimnel 
as usual in the group; width of mantle about a third the length. Fins very small, separate, delicate; 
attached for the anterior half of their inner margins to the minute and sharp membranous point which 
forms the posterior termination of the mantle. 
Head small. Eyes moderately small, projecting forward upon very short club-shaped stalks. Fun- 
nel enormous, reaching far beyond the head and more conspicuous than any other structure in the ante- 
rior region of the body; heavy- walled and inflated; apertiue large.

scarcely represented as suffi-

are probably shown as much 
too short and stocky.
