MIOCENE BEDS OF THE MALTESE ISLANDS. 525 
The British Museum possesses the portion of a left ramus, shown 
in Pl. XXV. fig. 1. It is No. 33243 of the Paleontological 
Collection, and was presented by Earl Ducie. The fragment is — 
incrusted with gypseous crystals and matrix of the Marl bed. 
Unfortunately the teeth are wanting; the jaw, however, in general 
characters is decidedly phocine, whilst the rather unusual depth of 
the horizontal ramus and the unusually high angle formed in front 
by the coronoid furnish important characters. 
_ Canine teeth of large size, and referable to Phocide, are common 
in the Sand bed, and are also somewhat plentiful in the nodule-seams 
of the Calcareous Sandstone. ‘Two portions, a fang and crown, in 
Mr. Wright’s collection, are from the black-grained variety of the 
Sand bed. The former shows a maximum girth of fang of about 
43 inches; and the enamel is rough, like that of the grinders just 
referred to. 
Thus the genus Phoca is represented from the Sand, Marl, and 
Calcareous Sandstone. 
SQuALODON. 
The well-known fragment of a jaw with three teeth in place, 
discovered by Scilla in Malta about 1670*, and now in the Wood- 
wardian Museum, Cambridge, is the only instance I know of carni- 
vorous Cetaceans from these beds. The matrix would indicate that 
it was obtained from one of the nodule seams of the Calcareous 
Sandstone. Hitherto it has been included in the genus Zeuglodon ; 
but the much smaller dimensions and more triangular and serrated 
teeth place it with Grateloup’s genus Squalodon. 
DELPHINUS. 
Professor Owen recognized remains of more than one species of 
Delphinus in Admiral Spratt’s collection from the Sand bed; and 
fragments of jaws with teeth in sitw were recognized by me in 
collections made by the late Captain Strickland from the Calcareous 
Sandstone. 
Large-sized Cetacean vertebrae are not uncommon in nearly all 
the beds, but especially in the Sand bed, where I also discovered 
the greater portion of a mandible t. 
HarirnEerium Scurnz1? Kaup. 
Remains referable to the genus Halitheriwm have been already 
recorded from Maltese Miocene formations, as follows :— 
1. A molar from a nodule bed of Calcareous Sandstone, and an 
“ ear-bone” composed of the periotic and tympanic, together with 
several caudal vertebrae, from the Sand bed§.
