XL.— Observations on the recent Foraminifera. 
By Witi1aM Crark, Esq. 
To the Editors of the Annals of Natural History. 
GENTLEMEN, Norfolk Crescent, Bath, Feb. 22, 1849. 
I nave for many years employed myself in malacological pur- 
suits, and had opportunities of observing some of the recent Fora- 
minifera, particularly those of the coralline zones of the South 
Devon coasts. 
As long ago as 1834-5, my friend Mr. Jeffreys of Swansea, — 
who by his extensive researches throughout the British Isles for 
new and rare Testacea has rendered eminent services in promo- 
ting conchological and malacological science, was on a visit to 
me at Exmouth, during which we had frequent disquisitions on 
the nature of those minute organisms which at that time were 
termed Cephalopoda ; I then strenuously advocated that they be- 
longed to the coralline group, and were of course polypiferous, 
and that I believed them, in their natural habitats, to be fixed, si- 
milarly to the great mass of Zoophytes ; these views, except on the 
point of fixity, have been fully corroborated by M. Ehrenberg’s 
observations, and during the last summer, 1848, I was enabled, 
by the occurrence of very recent specimens of Orthocera Legu- 
men, to ascertain some new facts relative to these foraminiferous 
polypes. It has been, I believe to this day,a matter of doubt, if 
they have at the anterior end tentacular filaments, and as proof 
in the affirmative, in Orthocera Legumen, I have specimens m 
which the dried linear cilia, about eight, are distinctly to be seen 
lying radiated in the external sulci of the striule of the aperture, 
and I have little doubt that the creature can withdraw them within 
the internal hollows of the striz.
