148 PARADISE POLYNEME. 



several separate processes or articulated rays : these 

 are, in general, much longer and more setaceous 

 than in the Trigla*, and, in some species, even 

 exceed the length of the whole body. The species 

 of Polyncme are not very numerous, and are chiefly 

 confined to the warmer latitudes. 



The Polynemus Paradiseus or Mango-Fish, as it

 tending about half the length of the body. The 

 colour of this fish is generally described as yellow, 

 and its popular name of Mango-Fish is supposed 

 to have been givea it from that circumstance, as

 with a tinge of blue on the upper parts : this may 

 have been owing to a change of colour on being 

 kept for a considerable time in spirits : the fila- 

 ments also in Dr. Bloch's specimen seem to have 

 met with some accidental mutilation, since they 

 are far short of the length usually represented by 

 other authors. Dr. Russel, in his work on the
