than broad, provided with a very slight lateral keel. The length of 

 the head is one-third of the total (without caudal) ; its upper sur- 

 face with a broad and very shallow median groove ; superciliary 

 region striated ; base of the intermaxillaries depressed, maxillary 

 nearly entirely hidden by the prseorbital. Teeth strong ; vomerine 

 teeth none. The diameter of the eye is less than the Avidth of the 

 interorbital space, and one-half of the lem/th of the postorhiial por- 

 tion of the head. Body subcylindrical, its depth being much less 

 than the length of the nectoral fin, which equals the distance of the 

 opercular margin from the orbit. Tonrjue covered with ttdmrnlar 

 aspetities. Ventral fin nearer to the head than to the root of the cau- 

 dal. The middle and hinder dorsal rays are very slender and some- 

 what prolonged, the last extending nearly or quite to the root of the 

 caudal. Caudal fin forked. Scales very thin and small, deciduous.

The free portion of the tail is tetiahedral, higher than broad, with 

 a slight, narrow longitudinal keel along the side. The length of the 

 head is contained thrice and a third in the total (without caudal) ; 

 its upper surface with a broad and very shallow median groove ; 

 superciliary region striated ; basc^of the intermaxillaries depressed, 

 maxillary nearly entirely hidden by the praiorbital. Teeth strong ; 

 vomerine teeth none. The diameter of the eye is two-thirds of the 

 width of the interorbital space, and two-fifths of the length of the 

 postorhiial portion of the head. Body slightly compressed, its depth 

 being much less than the length of the pectoral fin, which is more 

 than the distance of the opercidar margin from the orbit. Tongue 

 covered vj'dh tuhercidar asperities. Ventral fin midway between the 

 front margin of the eye and the root of the caudal. The nuddlc and 

 hinder dorsal rays arc very slender and somewhat prolonged, the 

 last extending nearly or quite to the root of the caudal. Caudal 

 fin forked. Scales very thin and minute, deciduous.
