Genus SIPHAMIA Weber 



Siphamia Weber, Notes Leyden Mas., vol. 31, 1909, p. 168. Type Siphamia 



tubifer Weber, monotypic. 

 Adenapogon McCulloch, Rec. Austral. Mus., vol. 13, 1921, p. 132. Type 



Apogon roseigaster Ramsay and Ogilby, orthotypic. 



Band of villiform teeth in each jaw, without canines and some 

 minute teeth on vomer; palatines with or without teeth. Preopercle 

 edge entire, ridge serrated (entire in Adenapogon). Gill rakers 

 lanceolate, about 12 on lower limb of first gill arch. Scales ctenoid 

 or cycloid (Adenapogon). Cheeks largely or entirely scaleless. Lat- 

 eral line complete. Silvery canal extends backwards on each side 

 from tongue to caudal peduncle near ventral surface. First dorsal 

 with 6 spines, anal with 2. Soft dorsal and anal with 10 rays. 



According to McCulloch the silvery lateral gland is likely a phos- 

 phorescent organ.
