Of the Barnacle. . ioi 



There is yet another Species of plate VI. 

 Barnacle of a f mailer Sort, to be Fig ' 7 * 

 found adhering alfo to Ships and 

 Rocks, which differs from thofe of 

 the larger Kind chiefly in this Par- 

 ticular, that the Shell immediately pi ate vr. 

 inclofing the Fifth, together with the 7- 

 Stem upon which it is fixed, is lodged 

 within another univalve Shell, in plate VI. 

 Shape a truncated Cone, adhering F/g ' 7 * a * 

 to the Ship as that of the Limpet 

 does, and may in Effect be eafily 

 miftaken for a Limpet. The Stem 

 however is tenderer, and much fhort- 

 er in Proportion to the Size of the 

 Fifh, than that of the larger Sort, 

 juft of a fufficient Length to enable 

 the Animal to exert its Apparatus 

 of Horns out of the Aperture of the 

 univalve Shell. The Trunk of this Plate vr. 

 Animal I have caufed to be deli- Fi &< 7» <*- 

 neated, as well as that of the other 

 Sort, to exprefs the Nature of both, 

 in which they differ fomething from 

 each other, the Trunk of the leffer 

 Barnacle inclofing a Tongue in Pro- 

 portion much longer than that of 

 the larger Sort, and, when fheathed, 

 gathered into fmall Spires.
