This is the sqnid which is usually recorded in British 

 catalogues, under the name of Loligo sagittata. We owe 

 to Mr. Alder and ]\Ir. Hancock, the recognition of its true 

 specific relations. Its body is elongated and cylindrical, 

 tapering below to an obtuse extremity, flanked in its lower 

 third by two triangular fins inserted well in upon its 

 back, and forming together a rhomboidal outline. Head 

 broad and short, not very prominent in the region of the 

 eyes, crowned with eight stout subulate arms, of which the 

 two lateral pairs are longest, and the inferior lateral crested 

 dorsally. The suckers are large and arranged in two rows 

 on each arm. Tentacular arms with stout peduncles, along 

 the whole of the upper surfaces of which are suckers 

 ranged in two rows ; on the long lanceolate clubs the 

 suckers become larger, and alternate with smaller external 

 ones ; at the extremity of the club they continue in two 

 ranks, but become very small. The back of the club is 

 crested. There are suckers on the lips surrounding the 

 beaks. The funnel is strong and large. The pen is 

 linear, three-ribbed, broadest at its superior extremity, and 

 ends in a spatulate expansion and a small conical cup. 



The following are the dimensions of an example, mea- 

 sured by Mr. Alder in February, 1851 : — Length (not in- 

 cluding arms), one foot, two inches and a-half ; length of 

 body, one foot ; of head, two inches and a-half; longest 

 arm, eight inches ; shortest arm, six inches ; tentacular 

 arms, one foot, one inch ; length of fin, six inches ; breadth
