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 differs 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 Ommastrephes. 
In the letter from the Rev. 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 difference 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. 
Ina 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
