entire skeleton of which has been set up by him in the Museum of 
Comparative Anatomy in Paris. This is the most complete example 
yet seen in Europe. The head is entire, and is remarkable for its 
great vertical depth, nearly equalling the lateral measurement (as 37 
to 40). This elevation of the head is principally due to the large size 
of the maxillary bones. 
The cervical vertebrz indicate an abnormal and probably unique 
condition, some of the elements being absent. M. Serres remarks 
that such a condition is without analogy at the present day. 
The persistence of the dental bulbs, the great size of the lower 
jaw, and the zygomatic arch, furnished with a strong spur which 
greatly increased the surface for the attachment of the masseter 
muscle, show that the Glyptodon clavipes was even better adapted 
than the elephant for a vegetable feeder.—E. F.

I.—On soME FORAMINIFERA FROM THE NortH ATLANTIC AND 
Arctic OCEANS, INCLUDING Davis’s STRAITS AND BArFin’s Bay. 
By W. Kircnen Parker, F.Z.S., and Professor T. Rupert Jones, 
F.G.S. 4to. 1865. (From the Phil. Trans. 1865, pp. 8325-341.

aes Memoir, communicated to the Royal Society by Professor 
Huxley, F.R.S., in 1864, has for its chief object the description 
of a certain group of Foraminifera, constituting the Foraminiferal 
portion of the fauna of a distinct Natural-history Province. An- 
other object that the authors set before them was the careful dis- 
crimination of such forms, and groups of forms, among the Forami- 
nifera as show strict zoological relationship, however much masked 
by dissimilarity of shape, but really recognisable by similarity of 
structure, among numerous puzzling gradations of equivalency, 
modified by varying conditions of growth, according to depth, salt- 
ness, and warmth of water. : 
The materials for the work were derived from (1st) Soundings 
in Baffin’s Bay, made during one of Parry’s Voyages; (2nd) Dredg- 
ings in Davis’s Straits, among the Hunde Islands, by Dr. P. C. 
Sutherland; (8rdly) Dredgings on the Coast of Norway, by Messrs. 
MacAndrew and Lucas Barrett ; and (4thly) Soundings in the North 
Atlantic, taken by Commander Dayman when exploring the Atlantic 
floor for the Telegraph-line. 
Some of these materials belong to what Naturalists term the 
«Arctic Province; but the North Atlantic belongs chiefly to the 
‘Celtic Province, and Captain Dayman’s soundings supply illus- 
trations of its abyssal fauna, Its littoral fauna on the east is to be 
found around the British Isles, and Messrs. Parker and Jones (with 
Mr. H. B. Brady’s help) drew up a corrected list of the British 
Foraminifera for this part of their subject. The western, or Ame- 
rican ‘littoral’ of the ‘Celtic Province,’ is called the ‘ Virginian ;’ 
and from this Dr. Bailey has figured and described some Forami-
