KEY TO THE GENERA OF CALLIONYMIDAE 

 la. Two dorsal fins. 



2a. No pelvic ray free or separate from others, all connected by membrane. 

 3a. Two lateral lines, the lower one represented by a fleshy keel or mem- 

 branous fold along the lower side of the body beginning opposite 

 anterior base of anal fin; opercular membrane ending in a free 

 flap; posterior part of maxillary semitubular in form with a very 

 short anterior and outwardly projecting concave lobe, scarcely 

 noticeable in small specimens; opercular opening superior in posi- 

 tion, above opercle, in form of a small foramen; pelvic fins con- 

 nected to pectoral base by a membrane attached opposite about 

 fourth to sixth pectoral ray from dorsal edge; upper lateral line 

 simple; no orbital tentacle; preopercular spine acute, with small 

 spines dorsally, and a small antrorse spine basally; soft dorsal and 

 anal rays all unbranched, except last one in each fin is branched to 



base Diplogrammus Gill 



36. A single lateral line located mostly in dorsal half of body, no thin fold 

 of skin along lower side. 

 4a. An orbital tentacle in combination with a broad fleshy lower lip 

 folded under chin; opercular opening a small foramen above 

 opercle; no free opercular flap; membrane of pelvic fin attached 

 as far dorsally as a little below middle of base of pectoral fin; 

 lateral Une simple; preopercular spine acute, with serrae dorsally 

 or ventrally and with an antrorse spine basally; all rays of soft 

 dorsal and anal fins unbranched, except last one in both fins 



branched to base Amora ^s (Gray) 



46. No orbital tentacle, or if a minute one occurs, lower lip not broad 

 and folded below tip cf chin. 

 5a. Pelvic fin membrane absent, no dermal membrane connecting with 

 the pectoral fin base; preopercular spine without basal antrorse 

 spine. 

 6a. Opercle ending in a free dermal flap; gill opening in a superior 

 position at rear of opercle; lateral line without elongate side 

 branchings; body very robust; all rays of soft dorsal and of 

 anal unbranched, except last one is branched to base. 



Eleutherochir ^^ Bleeker 



66. No free opercular flap of skin; gill opening superior in position 



above opercle; rays of anal unbranched, except last one is 



branched to base. 



7a. Lateral line with short branches at right angles; all rays of 



soft dorsal unbranched, except last is branched to base,
