STRUCTURE OF THE LANCELOT. 47

 Mr. Goodsir, who obtained two specimens, pro- 

 cured on the Manx coast, from Mr. Forbes, we 

 are chiefly indebted for a full and lucid descrip- 

 tion of this extraordinary croiiture, the lowest link 

 now known in the scale r4" vertebrate animals. 

 That it is a fish of singular character will at once 

 be conceded, when it is known that Pallas and the

 lot can no longer be retained even in the same 

 family with the last named fishes, but must assume 

 an ordinal value in any new arrangement of this 

 class.
