Dr. H. Woodward—On a New Genus of Fossil “ Calamary.” 3 
the animal,—the shaft of which is marked by three equidistant 
ridges, one median and two lateral (as in Acanthoteuthis tricari- 
natus),! which converge together at the very acute distal extremity ; * 
two extremely delicate lateral expansions, or alee (like the blade of 
a spear-head), are developed upon each side, and give rigidity to the 
two elliptical fins: these fins contract at #ths of the length of the 
body, and then expand again, so as to form a small distinct terminal 
fin, with a broadly-pointed extremity. The position of the ink-bag 
(placed on the median line, and distant exactly half the length of the 
body from the head); the impression of the horny mandibles, and 
the eyes, can be very well seen in the fossil. 
The head is surmounted by eight arms provided with minute 
hooklets? and acetabula or suckers; there are also traces of the 
two long and slender tentacular arms. 
As there is no fossil form of Teuthid, similar to this Lebanon one, 
in which the soft parts are preserved, we can only compare the 
characters of its internal shell. From these it seems at first sight 
proper to place it in Wagner’s genus Acanthoteuthis, which includes 
quite a number of species, from the Lithographic stone (Upper 
Oolite) of Solenhofen, Bavaria, having narrow elongated pens 
marked by converging ridges,? like those of the hving genus 
Ommastrephes. 
But this genus was originally founded upon the fossil hooks of a 
Calamary from Solenhofen, the animal of which had ten nearly equal 
arms, all furnished with a double series of horny claws, throughout 
their length. 
The fossil pens, like Ommastrephes from Solenhofen, have been 
also ascribed to these impressions of arms. 
Some of these Acanthoteuthids from Solenhofen, such as A. speciosa, 
A. Ferussacit and A. Lichtensteinii, were also considered by Wagner, 
as having belonged to Belemnites or to Belemnoteuthis.* 
Another series, namely, A. angusta, A. lata, A. subovata, A. sub- 
conica, A. acuta, A. brevis, A. intermedia, A. rhomboidalis, A. sent- 
striata, and A. tricarinata,> have been referred by Prof. Wagner to 
a distinct genus, Plesioteuthis, on the ground that they were not 
found associated with hooks; but, as Prof. Huxley well observes, 
he (Wagner) afterwards gave the same generic name to the hard 
undigested remains of naked-bodied Cephalopods “consisting of the 
middle keel of the pen, crushed into many short pieces, and of the 
hooklets of the arms, which, sometimes large, sometimes small, lie 
scattered round the fragments of the pen in great numbers,” found 
in the coprolites of reptiles in the Solenhofen slates. It would 
therefore appear that Plesioteuthis had hooks, though Wagner’s state- 
ment that he had never either in Miinster’s Collection or any other,
