UH JOHNSTON ON THE CEPHALOPODA OF BERW1CKSH1KE. 



face of the tciitaruln, and on the under surface of the fins ; eyes 

 without lids ; lips plaited ; surrounding the mouth and attached to the 

 base of the arms, there is a thin membrane with six angles, produced and 

 armed in the central aspect with very small suckers ; suckers of the arm* 

 biserial, of the tentacula quadriserial, and placed only on the enlarged 

 tips ; sac trilobate ; dorsal plate large, like a pen, the shaft being towards 

 the head. Length of the body sixteen inches, of the tentacula fourteen, of 

 the arms about six, but they are unequal, and some of them do not exceed 

 four, of the bone fourteen and a half inches. Makes an excellent bait for 

 cod, but does not occur in sufficient numbers to be used by our fishermen. 

 The ink is jet black. I have found the beaks of a small individual in the 

 stomach of a large one, so that it certainly feeds occasionally on its own 

 race. 



2. L. sagittata t the fins, with the tail, forming a triangular expansion ; 

 margin of the sac even ; dorsal plate narrow, three-ribbed, widest 

 at the apex and lanceolate, the inferior end saccate. Lam. Ani m. s.

This is commonly less than the preceding, and, from the shape and position of 

 the fins, the outline of the body is considerably different. The sac is 

 smooth, cylindraceous, tapered to a point below, the upper margin free, 

 even or only obscurely pointed in the middle of the back. The dorsal 

 plate is thin, narrow, strengthened with a rib down the centre and a 

 stronger one along each margin, widest and lanceolate at the top, whence 

 it gradually grows narrower until within an inch or so of the end, where 

 the ribs seem to unite in one, and the plate is again dilated and formed 

 into a pouch at the termination. The lip encircling the beaks is furnished 

 with numerous suctorial papillte; and the membrane at the 'base of the 

 arms is more or less distinctly divided into eight angular pointed segments. 

 Arms unequal in size, tapered, straight, with two rows of suckers ; tenta- 

 cula as long as the body, covered with suckers to within an inch and a half 

 of their origins, but at first the suckers are very small, and become sud- 

 denly larger towards the extremities ; all of them hang from a short 

 peduncle that has a lateral insertion, and small suckers, on longer 

 peduncles, are intermixed with the larger ; these are cup-like, and have the 

 margin armed with a horny denticulated ring. The ink is of a blackish- 

 brown colour, or dark olive-green. The stomach of a large specimen I 

 found filled with fragments of Alaria esculent a, on which the creature had 

 been feeding when taken, for pieces of the same were found between the 

 beaks half swallowed. It appears, therefore, that this species feeds occa- 

 sionally at least on sea- weed.
