46. Thalassidroma bulwert (Jard.), Bulwer’s Petrel.—There is 
a specimen from Greenland in the Leyden Museum, received from 
the Moravian missionaries (Schlegel, Mus. Pays-Bas, Procellaride). 
Prof. Reinhardt informs me that he tomas this specimen may 
have come from Labrador. 
47. Podiceps auritus (Linn.), Horned Grebe.—At least three 
specimens have been received from South Greenland; one from 
Nenortalik, Nov. 12th, 1828; afterwards two more. (Reinhardt, 
in lit.). 
In conclusion, I desire to thank those friends who have helped 
me in collecting materials for this list. I am especially indebted 
to the kindness of Mr. Ridgway, of Washington, Mr. Allen, of 
Cambridge, Mass., Professor Newton, of Cambridge, and Professor 
Reinhardt, of Copenhagen, who have given me much valuable 
information and assistance. 
THE MOLLUSCA OF THE ISLE OF MAN. 
By tHE Rev. T. Tavpor. 
(President of the Isle of Man Natural History Society.) 
A ust of the Mollusca of the Isle of Man has been prepared 
with the object of giving approximately complete information of 
what has been made known to the present time in this depart- 
ment of our insular fauna, and so to suggest a stimulus to further 
research. It contains the names of 209 species belonging to 
103 genera. 
This list, which it is proposed to publish in the ‘ Proceedings’ 
of our Society, is based on Forbes’s ‘ Malacologia Monensis,’ 
a small volume which he published in 1838, and ‘ The History of 
the British Mollusca and their Shells,’ which he, conjointly with 
Mr. Hanley, published in four volumes, 1848-1853. The former 
being of a local, the latter of a general character, it was not to 
be expected that in this latter work the Isle of Man would be 
noted as a locality for all the species named in the earlier 
volume, many of them being of general distribution. Ten years 
elapsing between the publication of this and the appearance of 
the first volume of the ‘ British Mollusca,’ this latter work includes 
several species found in or about the coasts of our island not men- 
tioned in the earlier publication. In the preparation of this list,
