162 PEOF. OWEN ON NEW AND EAEE CEPHALOPODA. 



eleven times its greatest breadth ; the number of the larger suckers is twenty-four, 

 twelve in each row, on each tentacle. The terminal fifth of the expansion gradually 

 attenuates to a point. 



In the above characters the following species, Ommastrephes sagittatus, d'Orb.^, 

 resembles the great Newfoundland Squid, but diifers in the larger relative size and 

 smaller number of the proximal group of the smaller tentacular acetabula. The larger 

 acetabula, moreover, are only eight in each row ; and these rows are closer together. 

 There is no trace, in any of the species figured, of the oblique ridges which divide the 

 alternating pairs of the larger tentacular suckers, which ridges, in the Newfoundland 

 Squid, are continued from those that define the shallow depressions from which the 

 large suckers severally project ; these seem to be sessile or to have very short peduncles. 

 The above characters, well shown in the photograph, I have not found figured or 

 described in any other species of Ommastrei)hes. 



In the letter from the Eev. M. Harvey, of St. John's, Newfoundland, accompanying 

 the photographs, " the eight shorter arms are " [stated to be] " each 6 feet in length 

 and 10 inches in circumference at the junction with the central mass." They are also 

 said to " taper to a fine point," to be " all armed with denticulated suckers, — in all 

 eleven hundred in the ten arms." The tentacles are stated to be " each 24 feet in 

 length, with suckers at the ends." "The eyes measured about 4 inches in diameter." 



These particulars are also given in the Rev. Mr. Harvey's letter to the London Stereo- 

 scopic Company, which is published with the photographs ; and with respect to the 

 subject of no. 2 he states: — "This large arm, cut off by the fishermen in Conception 

 Bay, measures 19 feet in length." This is, I conclude, the proportion of the 24 feet 

 previously allotted to the tentacle when entire. But in the note attached to photograph 

 no. 2 Mr. Harvey states: — "The entire length was thirty-five feet, 10 feet being left 

 attached to the body and 6 feet having been destroyed." But this would seem to be 

 given from the report of the boatmen. " The broadened extremity " (of the tentacle) 

 "is armed with one hundred and sixty sucking-disks, about 1;| inch in diameter." In 

 this enumeration the small and large suckers are counted together, and no notice is 

 taken of the well-marked diiference of size between the twenty-four suckers in the two 

 alternate rows of twelve each, and the intercalated smaller suckers, together with the 

 proximal and distal groups of still smaller ones, which are shown in both the photo- 

 graphs. 



It is probable that the diameter or breadth of the sucker relates to one of the larger 

 series. 



In a paper by Mr. A. Verrill " On the Cephalopods of the North-eastern Coast of 

 America"^ a brief notice is given of Mr. Harvey's Squid, in which a length of 17 feet
