THE MALTESE FOSSIL ELEPHAIvTS. 15 



the two stumps sticking in the jaw, as just recorded, besides a scar on the enamel of the 

 anterior talon, internally, 0'4 inch in breadth ; but the most suggestive part of the speci- 

 men is the succeeding alveolus, in which the collines a of the last milk-molar lie horizon- 

 tally, furnishing a maximum breadth olone inch. The crown of the penultimate tooth is 

 not sufficiently worn to show the pattern. The lower ramus No. 90 (fig. 2) has been 

 broken across in front just clear of the tooth, which, however, has a deep scar on the 

 enamel made by the antepenultimate. The last ridges are not perfectly consolidated. 

 The entire length of the crown is 1"8 inch, in which there are seven instead of six 

 ridges in the upper tooth. The last milk-molar a is seen in situ, showing a breadth of 

 colline of about 0-8 inch. As in the upper the antepenultimate and the first milk- 

 tooth also were possibly in wear at the same time, seeing that the digitations of the 

 first four ridges only are invaded. The colline a is nearly entire and well shown behind, 

 presenting dimensions equal to those of No. 44 (PI. IV. fig. 3), which appears to belong 

 to the last milk-molar of this pygmy form of elephant. 



Other teeth referable to A series are seen in my collection in the British Museum. 

 For example. No. 1, holding seven ridges, is an entire upper molar, 1'7 inch in 

 length, with a crown like figs. 1 & 2, just coming into wear, whilst No. 7 is more 

 attrited, and No. 8 is of the lower jaw, with only the first three ridges slightly worn. 



All these teeth demonstrate the presence of an upper and lower penultimate milk- 

 molar, holding seven ridges, or five plates and two talons. 



Intermediate in size between the above and B Series are a number of small lower 

 teeth, somewhat larger than the former, with figmentary posterior talons raising the 

 ridge-formula by one ridgelet. They difi'er, however, in no other particulars, and 

 may be regarded as belonging to A type, with the usual variety of an additional 

 ridge. 



The diflaculty in deciding what should be called a plate and talon is shown in the 

 lower molar. No. 75 (PL I. fig. 9). Here the first ridge is quite independent of the 

 second, and the last is a mere triangular splint attached to the seventh ridge. Tlius 

 this molar might be said to contain seven plates and a posterior talon in a space of 

 1-7 inch. 



The rhomboidal tendency of the disks is here also apparent, with slight crimping 

 about the middle ; but the crown is not quite half-worn. 



Conditions precisely the same as in fig. 9 are shown by the ridge-formulse in Nos. 3, 

 4, 6, & 10, which represent lower molars in various stages of wear, the half-worn crown 

 of No. 6 displaying disks in no way distinct from those of PL I. fig. S. These molars gra- 

 dually increase in length up to No. 9 (fig. 15), which is 2 inches in length, with its seventh 

 plate convex, and a triangular figment at a constituting a posterior talon. A similar 

 specimen of a lower molar is shown by No. 62, which holds seven ridges in 1*8 inch, 

 neither of which, however, might be considered other than plates, the part of the 

 surface of the seventh ridge which gave rise to the little ridgelet in the preceding
