As in rodents, it is their outer surface only which has a coating of 

 enamel, which is slightly grooved longitudinally, and it is this enamel 

 which forms the cutting edge of these two teeth, and the worn 

 surfaces together take the form of a semicircle or crescent-shaped 

 space, as shown in Fig. 2.

The general shortening and thickening already mentioned as being 

 so noticeable in the skull appears to have been characteristic of the 

 whole animal, for this tendency is also very strongly marked in the 

 limb-bones. Figs. 3 and 4 show respectively the metacarpal and 

 metatarsal of an adult, the former being 55 mm. in length and 21 mm. 

 in width at the middle of the shaft, while the latter is 59 mm. long 

 (without tlie tarsals) and 19mm. broad at the middle of the shaft; 

 the proportions of these two bones are unlike those of any with which 

 they have so far been compared. In some specimens, even when still 

 immature, the distal row of the tarsals (cuboid, navicular, and 

 cuneiform) are fused to the third and fourth metatarsals, as occurs 

 in birds. 



The Pleistocene mammalian fauna of an island almost always proves 

 to be of great interest, and generally includes the remains of either 

 primitive survivals related to a Tertiary fauna or forms specially 

 adapted for existence in a restricted habitat, such as the pigmy races 

 which occur in several of the Mediterranean Islands. The case of 

 M. halearicus seems to be somewhat obscure ; its goat-like cheek-teeth
