DESCRIPTION OF A SQUALUG. 349 



foundly striated, on their superior por ion these striae 

 are transverse and very rugose, on their middle por- 

 tion they are oblique, and towards the extremity they 

 have a longitudinal direction and are rugose; these 

 appendices are at present of the length of 2 feet 8 

 inches, but having been detached from the animal, 

 and in order to skin and prepare them, and again ad- 

 justed in their proper situation, their form seems to 

 have been entirely lost, a large groove, however, and 

 two small appendices are still recognisable ; anal 

 subtriangular, with a detached pointed lobe behind, 

 placed behind the second dorsal, its length is 1 footS 

 or 4 inches, and height 7 inches 6 liues ; tail 3 feet 

 3 inches long from the base of the second dorsal to 

 the base of the caudal fin, at which latter point 1 did 

 not perceive any indentation like those which exist in 

 the Squalus peregrinus of Blainville (Ann. du Mus.) 

 and in many other species, as well as in some that we 

 observed on the coast of New Holland ; possibly this 

 character may have existed in the animal under con- 

 sideration, and their absence may be attributable to 

 dessication ; caudal fin large, straight, elevated, fal- 

 ciform, of the length of 5 feet from the extremity of 

 one lobe to that of the other ; superior lobe 4 feet 3 

 inches and 6 lines long, inclusive of the small trian- 

 gular lobe at its extremity of 8 inches 6 lines ; infe- 

 rior lobe short and wide ; on each side of the tail is 

 a carina of about 1 foot 6 inches or 2 feet long, which 

 crosses the base of the caudal fin.
