A. detached tentacular arm, belonging to a species of Chiroteuthis, was taken 
at station 303, Lat 41° 34' 30", Long. 65? 54' 30", in 306 fathoms. 
This arm is very long and slender ; the length being 780 mm. (or over 30 
inches); its diameter being from 1.5 to 2 mm., exeept near the base, where it 
is 3 mm., and at the terminal club, which is 6 mm. broad and 54 mm. long. 
The arm is white, with purplish specks, and is generally roundish, except at 
the club; along the greater part of its length there is a row of rather distant 
sessile suckers, the distance between them being usually from 12 to 18 mm. ; 
these suckers are larger than those of the club, and have a nearly flat upper 
surface and no horny marginal rim. A row of small, simple, scattered pits, 
perhaps homologues of these suckers, extends up the back side of the club. 
These smooth suckers evidently serve to unite the tentacular arms together, 
when used in concert. The club is stouter than the rest of the arm, convex 
on both sides, and. but little flattened; on each side it is bordered by a well- 
developed marginal membrane, supported. by a series of transverse thickened, 
but flat, tapering muscular processes, with their ends projecting at the edge 
of the membrane, as digitations; on the distal half of the club these are sepa- 
rated by spaces greater than their breadth, but on the proximal portion they 
become forked and erowded close together, showing only narrow intervals or 
merely a groove between them. At the tip of the arm there is a thick, ovate, 
dark purple, spoon-shaped, hollow organ, about 4 mm. long, with its opening on 
the back side of the arm. This so strongly resembles the spoon-shaped organ of
