lakes and rivers by its tusks and daws ; and he alludes 

 to its claw resembling that of the Pangolins. MM. 

 Blainville and Durneril consider the dinotherium to have 

 been allied to the larnantins, or "aquatic gravigrades," 

 — to have been in fact a dugong wirh tusk-incisors, and 

 therefore one of the concluding fornis of the Pachyder- 

 mata. They consider that it had no proboscis, but a 

 huge inflated muzzle and upper lip. Gstger places it 

 with the seals. Now, as regards M. Kauji's theory, we 

 may at once state that the claws and scapula on which 

 he founds it are not proved to belong to the dinotherium; 

 and he himself admits that, should the discovery take 

 place of other fossil relics whence the certain existence 

 of a Mania rjigante might be presumed, his theory 

 would be overthrown. Our own opinion coincides with 

 that of M. Blainville. The occipital condyles (see the 

 posterior view of the skull seen from below, Fig. 68, and

the skull Fig. 64) are terminal, or in the direction of the 

 longitudinal axis of the skull, as in the larnantins, and also 

 the cetaceous mammalia modified for aquatic existence. 

 The occipital surface is larcre, subvertical, and even in- 

 clined from before backwards, with a profound mesial 

 depression for the insertion either of a very stron? cer- 

 vical ligament or powerful muscles for the elevation of 

 the head. The basilary portion of the skull (Figrs. 66, 

 67) is narrow in its component parts, while the vertical 

 surface (Fig. 64) is, as in the larnantins and durrongs,
