136 NEW SPEC IKS OF FISH. 



the semidia meter of the eye. The inferior very 

 long and flexible. The eye is nearly black, with the 

 upper part of the iris silvery. The scales large. The 

 blue color is most prevalent, particularly upon the 

 tipper part of the body, paler along the sides, and ar- 

 genteous upon the abdomen, the head of a clear blue, 

 and silvery, the tail yellow and bluish ; beak brown 

 and deep blue. 

 P. lO.— V.6.— D. 14.— A. 12.— Caudal 20 to 24. 



Uab. near Guadaloupe and Martinique, where it 

 is called Balao. 



Hemtrjvmphus *balao. Body four times the length 

 of the lower jaw, pectoral fin a third part shorter than 

 the lower mandible ; anal fin half as long as the dor- 

 sal fin. 



It is sufficient to cast an eye over the two figures to 

 recognize their difference, although the two species 

 seem to be the same. In this the body is more elon- 

 gated and less equal, more elevated upon the back, 

 and more attenuated towards the tail, in this also the 

 fins are longer, the lobes divided by a longer notch 

 are pointed, narrower, and the inferior more elonga- 

 ted : the pectoral, dorsal, anal and ventral fins also 

 more developed, the interior point of the ventral more 

 prolonged ; the snout shorter, and lower towards the 

 throat, the lower mandible likewise shorter, but with 

 the upper nearly as in the preceding species. The 

 lateral line commences directly from the gorge, con- 

 tinues along the abdomen as far as the ventral fins.
