0. Skull of a young specimen. Greenland. From Dr. Edward Riip- 



pell's Collection. — The front of the lower edge of the lower jaw 



of this young specimen is scarcely dilated. 



The skeleton and two skulls of this Seal are described in Cat. 

 Osteol, Coll. Mus. Coll. Surg. 646. no. 3961. 



" Several Harp Seals are now seen in the deep sheltered voe at 

 Balta Sound. 



" This Seal can scarcely be considered very rare here, but it is said 

 only to occur in bad weather, and certainly the present visit forms 

 no exception to the rule, the wind having for some days been blowing 

 heavily from the north-east, accompanied by sleet and snow." — 

 H. L. Saxhy, Balta Sound, Shetland, March 14, 1864, 'Zoologist,' 

 1864, p. 9099. 



At a brewer's in Spring-grove Lane, Isleworth, there is a stuffed 

 specimen of a Seal that was caught on the 25th of March, 1858, in 

 the river Thames at Isleworth, which appears to be a young specimen 

 of this species ; unfortunately the bones which would have deter- 

 mined the question were destroyed, or at least not kept. 



" The Ground Seal, which forms the larger j^art of the prey of the 

 Northern sealers, has the colour and markings like the male Saddle- 

 back, but it is more robust ; it is perhaps Ph. leporhia, or the ' Hare 

 of the- ^ear'—WaJlace, Pvoc. Roij. Phys. Soc. Edinh. 1862, 390. 

 This cannot be, as that has not the mark on the back. 



M. Gaimard, in his 'Voyage to Iceland and Gi'eenland,' Mammalia, 

 pi. 11, devotes a plate to the skull and teeth of the Seals of Ice- 

 land and Greenland ; but he does not pay any attention to the form 

 of the lower jaw, except incidentally, when representing the teeth 

 of the lower jaw of his P. anneUata (t. 11. f. 9). I may observe that 

 this author names on his plates what we call Phoca annellata P. his- 

 pida, and what we call P. Gh'oenlandica P. annellata. — P. Z. S. 1864.

The palate of the skull arched out behind. Cutting-teeth ^. 

 Grinders 3 or 5, lobed, compressed. The lower jaw strong, bowed 

 out on the sides, thick in front, and with a low crest on the inner

 Halicyon, Gray, P. Z. S. 1864, p. 28. 



In Pagophihis Grcenlandicus and Halicyon Richardi the angle of 

 the lower jaw is far back, and the hinder edge of the ramus ascends
