12 MR. A. L. ADAMS ON THE OSTEOLOGY OF 
posteriorly. The single hollow fang has been recently broken off about 0-4 inch 
below the crown. ‘There is a pressure-hollow 0°3 inch broad on the upper and 
posterior side of the fang. The tooth is made up of five ridges, or three plates and 
two talons. Here the first and last ridges may be called modified ridges; at all events 
the posterior fairly claims to be considered a talon. The crown is 0°55 inch in length. 
The ridges are moderately thick, but not quite so large as in the last. 
The above is probably a lower molar, and does not seemingly differ in character 
from the last. The anterior ridge also rises from the common base, but is not quite 
so large as in fig. 3. 
3. Specimen No. 103 (fig. 4) might, from the figure, be considered a good deal 
larger than either of the foregoing; and this is the case to a trifling extent; but from 
injury some time or other there is a lengthening of the crown which is not natural. The 
enamel also of the posterior talon has been denuded, and the single hollow fang was 
broken off recently at about 0:5 inch below the crown. ‘The pressure-hollow, 0:3 inch 
in breadth, and a scar are well seen on the back part of the fang. There is no indi- 
cation of wear on the crown, which from its narrow front might have belonged to the 
lower jaw. The first and last ridges claim the character of talons, being simple splints. 
It contains the same ridge-formula as the last. The length is about 0°6 inch. 
The ridges in this and fig. 5 are almost the same thickness. From its breadth the 
above may have been an upper tooth. 
4. No. 109 (fig. 6) is a well-worn crown. There is seemingly a trace of an anterior 
ridge which had been worn out, possibly by pressure or attrition, leaving the enamel 
of the next bare and rough. The flat, single, straight, solid fang is entire. It is com- 
pressed laterally, with a small opening at the extremity for the nutrient vessels, and is 
0:8 inch in length. The enamel on the posterior ridge has been denuded, and there 
are two caries-like erosions, one immediately under the crown behind, and another 
in front. 
Although only three ridges remain, it may be there were two more. The length of 
the crown is 0-4 inch, and, although well worn, shows no pattern of any value for 
comparison with succeeding teeth. 
The enamel of the plates in this molar is not seemingly so thick, nor are the plates as 
in any of the preceding; and altogether the tooth would appear to have belonged to a 
smaller animal. 
Mr. Busk has kindly allowed me to compare Admiral Spratt’s collection of Zebbug 
molars, figured and described by Dr. Falconer, with the above; and seeing that, com- 
bined with my own, they comprise all the first or second milk-teeth of the Maltese 
Elephants yet discovered, I must briefly refer to them also. 
The similarity between the lower tooth described by Falconer! and the last is very 
striking, even in the caries-like erosions just under the crown, posteriorly, where a
