On the Occurrence of the Genus Anser in the Peat and Gravel Deposits 
in Cambridgeshire. By J. F. Warxnr, B.A., F.G.S. 
Among the bones which I have obtained from the Cambridgeshire 
fens, I have detected the humerus of a species of goose. With the 
kind assistance of Mr. Dallas, I have compared this bone with those 
of the skeletons of geese contained in the valuable collection of 
comparative osteology in the York Museum ; and it appears to agree 
in all its essential characters with the right humerus of Anser ferus. 
I am not aware of the occurrence of this bird in the fens having 
been previously recorded, although its presence there might have 
have been expected. The bone is of the dark colour proper to those 
found in the fens. 
A more interesting discovery is that of the right humerus of a 
distinct and larger species of the genus Anser, obtained from the 
gravel deposits near Cambridge, which contain species of elephant, 
rhinoceros, horse, &c. associated with Cyrena fluminalis and exist- 
ing land and freshwater shells (see a paper by Mr. H. G. Seeley in 
the Quarterly Journal of the Geological Society for 1866, p. 475). 
This bone is larger in every respect than the one which I have re- 
ferred to Anser ferus ; its total length is 62 inches, diameter of the 
shaft =%, inch, greatest breadth across the proximal end 1} inch, 
and breadth of distal extremity 1, inch. The pneumatic foramen 
is not only relatively, but absolutely smaller than that in the 
humerus of Anser ferus. Dr. Buckland figures (Reliquiz Diluviane, 
pl. xii. figs. 9, 10) a fragment of the humerus of a bird from the 
diluvium of Lawford near Rugby, which he considers to have be- 
longed to a species of Anser. The bone figured by Dr. Buckland 
seems to be nearly of the same size as that in my possession ; but if 
we may trust the figure, its shaft had a rather stronger curve, and 
the structure of the proximal portion was not quite the same.

A new importation of these beautiful sponges; they are offered 
under the name of “ Scekrebs-Nest (that is, Sea-Crab’s nest), which 
are only found on the Island of Zebu, and are imported from Manilla.”
