 the inguinal ones larger; length 114-, breadth, 6 inches. 

 Shaw's figure scarcely shews the rugosities or the keel suffi- 

 ciently distinctly. Mr. Bell's specimen may be discoloured, 

 it difters in being livid grey, and the spots impressed and as 

 if burnt into the horny coat.

 specimen, except in that the first vertebral plate is not urn- 

 shaped, and Lesueur does not notice the triangular temporal 

 spot.
