526 A.L. ADAMS ON VERTEBRATA OF THE 
penultimate true molar) in my work on Malta*, from the Lower 
Limestone. 
3. In the notice of the foregoing I refer to a fragment of a jaw 
with two teeth in situ. This interesting relic, now in the British 
Museum, was found in Gozo, and might have been lost but for the 
vigilant eyes of Mr. Wright, who brought it to the notice of Admiral 
Spratt. It is the specimen examined by Falconer, and which he 
compared with Halitherium and Listriodon, and has justly referred 
to the formert. The limestone matrix seen on the specimen 
indicates the uppermost or else the lowermost formation ; which, it is 
impossible to say. 
The specimen No. 4085 is a fragment of a left maxilla, about 33 
inches in length. The outer table is removed, showing the fangs of 
the penultimate true molar. Part of the socket of the ultimate 
molar remains; the penultimate is entire, whilst the antepenultimate 
has lost a portion of the crown externally. The crown of the last 
premolar is broken off; and a pit in front indicates the position of 
the preceding tooth. 
The jaw is shown, crown and profile, natural size, in Plate XXY. 
figs. 8 and 3a. The second true molar is quite unworn, like the 
preceding specimen. It displays the two ridges with a deep open 
internal valley and the two pits, one anteriorly and the other on the 
posterior aspect of the crown. ‘The dimensions of this tooth are as

4, The broken crown from Mr. Wright’s collection (Plate XXYV. 
fig. 4) carries good evidence of the formation in which it was found, 
being incrusted with a matrix of red sand from the Sand bed in 
Gozot. The crown-pattern is characteristic; and the tooth is pro- 
bable a penultimate true molar of the mandible. 
5. Several vertebree covered with clay and crystals of gypsum, 
together with fragments of ribs, are in the British Museum. They 
show that they were derived from the marl and nodule seams of the 
Calcareous Sandstone, whilst the characters assimilate to the same 
parts of Halitherium, not so cogently, however, as the preceding. 
I take this opportunity of correcting a mistake made in my former 
communication to the Society§,wherein I state that remains of Dugong 
are also found in the Maltese rocks. This I have since discovered is

{ Professor Owen, as far back as 1843, recognized bones, “apparently of a 
Manatee,” in Admiral Spratt’s collections from the Sand bed (Proce, Geol. Soe. 
London, vol. iy. p. 230).

besides the Halitheriwm.
