syngnathidj:. 



changeable iridiscence, and variable tints of blue dispersed 

 over different parts of the bead, body, and tail. 



I have not included any reference to Linnseus or Bloch in 

 the synonymes, being doubtful that the species are identical 

 with the one here described. Klein's figure, No. 10, very 

 closely resembles the H. brevirostris ; and by the description, 

 the H. antiquus of Risso is also the H. brevirostris of 

 Cuvier.
