Salanqin^:. — Argentinidse with the dorsal fin placed far 

 behind the pelvics, the head depressed, flat above, and the body 

 elongate, subcylindrical anteriorly and compressed posteriorly. 

 Teeth conical ; scales deciduous; 4 branchiostegals ; pelvic 

 fins 7-rayed *. 



Synopsis of the Genera. 



I. Pra>maxillaries subnormal ; lower jaw projecting. 



A. Dorsal tin entirely in advance of tbe anal ; tongue with 2 series 



of teeth ; 2 series of teeth on each side of tbe palate ; teeth in 

 the jaws small, subequal 1. Protosalanx, gen. now 



B. Dorsal fin partly above the anal ; tongue toothless : 1 series of 



teeth on each side of the palate. 



Teeth in the jaws small, subequal 2. Salangichthys, Bleek. 



A pair of canines near the symphysis of the 

 lower jaw; praeinaxillary teeth some- 

 what enlarged, strongly recurved 3. Hemisalanx, gen. nov. 



II. Pra?maxillaries forming an anterior triangular expansion; lower 

 jaw not projecting ; a single series of teeth on each side of the 

 palate; 1 or more anterior canines in the lower jaw, perforating 

 the roof of the mouth behind the prsemaxillary expansion ; pra3- 

 maxillary teeth strong, recurved, set rather far apart. 



A. Dorsal fin entirely in advance of the anal: tongue with a single 



series of teeth ; lower jaw ending in a short fleshy appendage. 



4. Leucosoma, Gray. 



B. Dorsal fin wholly or partly above the anal ; tongue toothless. 

 Lower jaw ending in a short fleshy ap- 

 pendage 5. Salanx, Cuv. 



Lower jaw ending in a distinct, more or less 

 movable preesymphysial bone, with a 

 double series of teeth 6. Parasalanx, gen. nov. 



* In Protosalanx, Salangichthys, Hemisalanx, and Parasalanx, and 

 probably throughout the group, the males have the outer pectoral ray 

 produced and the anal tin modified, the middle rays being set close 

 together and curved backwards, whilst on each side of the body a single 

 longitudinal series of adherent scales, decreasing in size posteriorlv, is 

 placed above the base of the fin.
