Lonchurus dipressus Blocli & Schneider, Syst. Ichthyol., 102, 1801 (Surinam). Cuv. & 

 Val., Hist. Nat. Poiss., v, 195, 1830 (copied). Giinther, Cat. Fish. Brit. Mus., 

 ii, 317, 1860 (West Indies). 



Habitat. — Coast of Guiana. 



This remarkable species we have had no opportunity to examine. 

 We follow the suggestion of Dr. Giinther, in regarding the nomiual 

 species, Lonchurus depressus, as a synonym of L. lanceolatus.

Pogonias Lace"pede, Hist. Nat. Poiss., iii, 138, 1802 {fascial us — cromis). 

 Pogonathus Lacepede, Hist. Nat. Poiss., v, 121, 1803 (oourMna = cromis). 



Type: Pogonias fasciatus Lacepede. 



This genus contains, so far as known, but a single species, a large 

 coarse fish of our Atlantic coasts.
