The lateral line runs through seventy or more scales; above are six rows, 

 and below seventeen rows. 



There are five very long pectoral filaments, their length being twice as great 

 as that of the body. 



If the American and Afrioan representatives of this genus have been cor- 

 rectly referred to one species, the geographical range of that one is very wide. 

 The habitat of the species was given neither by Artedi in the Thesaurus of 

 Seba, nor by Gronovius in the Museum Ichthyologicuin. It was first said to in- 

 habit the American seas by Linnaeus in the tenth edition of his Systema 

 Naturse, and the same locality is given by Gronovius in a work that was long 

 imprinted; but which has been recently published by the British Museum. 

 If the American and African species are distinct, Bennett's name of Pohpiemus 

 Artedii must be therefore retained for the latter. Bennett alluded to the dis- 

 crepancies between the figures and descriptions of Gronovius and Artedi, 

 and the characters of the African species, but as Dr. Giinther, with specimens 

 from both localities before him has unhesitatingly united them under one, 

 without comment, it is probable that there is no real difference. The species 

 may therefore for the present be combined.
