being placed more longitudinally, and in the lower jaw being slender, 

 and without any angle on the hinder part of the lower edge. It is 

 far more nearly allied to that genus than to StenorJiynchus, to which 

 Prof. Owen (Ann. N.H. 1843, xii. 331, 332) has referred it ; observing 

 that his Sten. serridens (our Lobodon cancrivora) shows modifications 

 of the molar teeth which would give it a better claim to subgeneric 

 distinction than the Sten. Weddellii (which, he observed, is the type 

 of the subgenus Leptonyx of Mr. Gray) has been supposed to possess. 



Prof. Owen made this remark, and drew up his specific character, 

 without having seen the teeth of this species ; for the skuU was not 

 then removed from the skin, and the specimens in the British Museum 

 were stuffed with the mouth nearly closed. 



This animal is easily known from StenorJiynchtis by the shortness 

 of the wrist and the triangular form of the fore feet, being interme- 

 diate in this respect between that genus and Ommatophoca. 



Mr. Swainson, in 1832, applied the name of Leptonyte to a genus 

 of birds, and in 1837 the same name to a second ; but the former 

 had before been named Pteroptochos, and the latter Ooryphospiza, so 

 that the name may still be used for the Seal.

N.B. When this species was first described, I thought it was the 

 Leopard Seal of WeddeU. I was afterwards induced to believe that 

 I was mistaken, as the name Sea Leopard was applied by the whalers 

 to Stenorhynchus Leptonyx ; but it would appear that they used the 

 same name for the two Seals ; and I have convinced myself, by exami- 

 ning the teeth of WeddeU's specimen in the Museum of the Univer- 

 sity of Edinburgh, that my first opinion was correct.
