before the Society some years ago.

On soME PALLIOBRANCHIATE SHELLS FROM THE IRISH ATLANTIC. 
By Professor W. Kine. 
Tue shells described in the present communication were obtained through 
the soundings and dredgings conducted by Staff-Commander Richard 
Hoskyn, R. N., in 1862, at the time commanding H. M. S. “ Porcupine,”’ 
for purposes in connexion with the then proposed telegraphic commu- 
nication between Ireland and Newfoundland. 
The general result of these soundings, in a natural history point of 
view, has already been published in various papers ;* I now propose to 
give some information on four species of shells—all of the kind yielded 
by the expedition—belonging to the class Palliobranchiata, 
Order—Awncytopracuia (J. EH. Gray). 
1. Terebratulina caput-serpentis (Linnzeus). 
A fragment of a shell, which I have some doubts in referring to 
this species, came up, along with rounded pieces of a Cellepore, from a 
depth of 495 fathoms, in N. lat. 51° 3’, W. long. 14° 562’. 
The species is somewhat common on much shallower bottoms on the 
west coast of Ireland.

nary Notice of the Organic and Inorganic Objects obtained from the Soundings of 
H.M.S. ‘ Porcupine,’ &c., in ‘‘ Nautical Magazine,’”’ November, and December, 1862 ;

between Ireland and Newfoundland,” in ‘‘ Nautical Magazine,” December, 1862; and

‘‘Fraser’s Magazine,” October, 1863. The Lords of the Admiralty at the time gave 
instructions for all the specimens procured during the expedition to be placed, as far as 
practicable, in his hands for publication.
