On Pentacrini in Great Oolite near Basle. 49 
Miller, in a cigar-box, and therefore the animal had existed 
for some months without water. How, then, had it lived? 
It appears to me that the animal had breathed atmospheric 
air by the right side of its pulmonary chamber, which the 
researches of Jourdain and Sabatier have shown to be vascu- 
larized, but bad died on account of having received no help 
from the left side of the pulmonary chamber, which contains a 
ctenidium. The fact that a Helix punctata which Mr. George 
also brought over in the same box was alive until yesterday, 
when I dissected it, shows, I think, that Ampullaria, though 
amphibious, cannot exist out of water for a lengthened 
period of time. 
Note.—Since sending the above to press I find that the 
name I propose has been preoccupied by Lamarck. I there- 
fore, in its place, suggest for it the name of Ampullarta Georgii, 
after the gentleman who found it and sent it to me.—

A MEMOIR entitled ‘ Description des Fossiles de la Grande 
Oolithe des environs de Bale,’ by Mons. Edouard Greppin, 
and consisting of 137 pages of text, with ten plates, was pub- 
lished early this year in the ‘ Mémoires de la Société Paléon- 
tologique Suisse,’ vol. xv. (1888), at Basle and Geneva. M. 
Greppin, whose collection I had the pleasure of working 
through last summer at Basle, kindly gave me for examination 
some stem-joints of Pentacrinus which were new tome. He 
has printed in his memoir (pp. 133, 134) extracts from the 
letter that I wrote him anent these specimens ; my drawings, 
however, he was unable to reproduce. ‘T’o found a species on 
stem-fragments is, though good may come, to do evil; but to 
describe a new form without adequate illustration is utterly 
condemnable. I hasten therefore to complete the description 
by the accompanying figures, and at the same time would 
wish to borrow from M. Greppin’s work such an account of 
the rock and of the associated fossils as may invest with in- 
terest an otherwise dry communication.
