 consisting of five tubercles like the other ; the 

 whole skin is rough, with small tubercles.

 hue, reaching within an inch of the tail ; on the 

 belly, just opposite, is another of the same 

 form ; the belly is of a bright crimson color ; 

 the tail and anal fins are purple; the pectoral 

 fins are large and broad, almost uniting at 

 their base ; beneath these is the part by which 

 it adheres to the rocks, &c. ; this consists of 

 an oval aperture, surrounded with a fleshy 

 muscular and obtuse soft substance, edged with 

 small thread-like appendages, which concur as 

 so many claspers ; by means of this it adheres 

 with vast force to any thing it pleases. As a 

 proof of its tenacity we have known, that on 

 flinging a fish of this species just caught, into a 

 pail of water, it fixed itself so firmly to the 

 bottom, that on taking it by the tail, the whole 

 pail by that means was lifted, though it held
