PROF. OWEN ON NEW AND RARE CEPHALOPODA. 155 
I estimate the combined breadth of the terminal fins in Enoploteuthis cookii when 
recent, taken at the outer angles, to have been not less than 1 foot 4 inches. 
In the desiccation of the body-skin the transverse arrangement of the superficial 
muscular fasciculi is indicated; the thinner and more yielding ventral wall is shown 
by the median longitudinal infolding of that part in the process of drying. 
Considering that so much of the fleshy part of the great hooked Squid was cooked 
as to serve the appetites of at least three, and perhaps four, of those at table in the 
Commander's cabin, I infer that a goodly proportion of the body anterior to the fins 
went to the culinary galley, and that the basal attachments of the fins did not extend, 
as in Enoploteuthis lesueurii, to the fore margin of the mantle. 
On the supposition that the proportion in advance of the fins was that which is 
shown in Onychoteuthis raptor (Pl. X XIX. fig. 1), one may set down the length of the 
body of Enoploteuthis cookii at 3 feet. The length of the head to the setting-on of the 
arms would be, according to the same proportions, about 10 inches; and the length of 
the longest arm might be 15 inches, of which the terminal half may have been cut off 
for Hunter’s collection. If the outstretched tentacles were each as long as the body, 
3 feet may be added to the combined length of head and body to give an approximate 
idea or estimate of the total length of the Cephalopod in question, viz. 6 feet 9 inches. 
I have ventured on a reduced restoration in fig. 1, Pl. XX XIII. 
In a work on the Natural History of Chili, of which the second edition appeared in 
1810, the author, on the authority apparently of the latitude and longitude assigned 
by Lieut. Cook to the place of capture of his great hook-armed Cuttlefish, includes it 
in the Chilian fauna; but, as he adds nothing to the quotation from Hawkesworth’s 
account of the voyage (anted, p. 146), I conclude that he had not received or seen a 
second specimen of this remarkable species. All that is given relative thereto in 
Molina’s work is, verbatim, as follows :— 
“Oltre alla Seppia officinale si ritrovano nel mare Chilese tre altre specie di Seppie 
assai singolari. La prima é la Seppia unguiculata, la quale é di gran mole, ed ha in 
luogo di succhiatori le brachia, 0 sianoi due lunghi tentacoli armati da un doppio 
ordine di artigli o unghie acute simili a quelle del gatto, che si ritirano, come esse, in 
una sorta di fodero. Questa specie é di un gusto delicato, ma non é molto comune 
in quel mare, dove fu osservata dal cel. Banck nel primo viaggio del Cap. Cook.”— 
Saggio sulla Storia Naturale del Chili, di Gro. lenazio Mo.ina, seconda edizione, 4to, 
Bologna, p. 175 (1810). 
M. d@’Orbigny, referring to the above work, merely observes, with regard to the 
nomen specificum, that the term “wngwiculata” is objectionable, seeing that it is a 
character common to the genus, in fact the essential character of the section Enoplo- 
teuthis. But as to his proposition to substitute the name of the Italian compiler, I think 
Cephalopodists will agree that in common justice the honoured name of the original 
describer should be attached thereto. Dr. Leach desired to do honour to the captor of 
you. XI1—Part v. No. 4.—June, 1881. 2¢
