 teeth long, the posterior short; teeth of lower jaw slender, distant, 

 unequal. Scales deciduous, those of lateral line enlarged. Fins all very 

 small ; ventrals entirely behind dorsal, their distance from front of orbit 

 twice that from base of caudal ; distance from front of dorsal to base of 

 caudal half its distance from tip of snout; caudal widely forked. Dusky 

 olivaceous ; sides of head silvery ; bases of fins generally black ; rami of 

 mandible each with a double series of minute phosphorescent spots.

Paralepis, Risso, Hist. Nat. Eur: Merid., in, 472, 1826, (coregonoides). 



Head and body elongate, compressed, covered with deciduous scales, 

 those of the lateral line being the largest. Cleft of the mouth very 

 wide; maxillary developed, closely adherent to the intermaxillary. 

 Teeth unequal in size, some in the mandible and on the palatine bones 

 being rather larger than the others ; they are arranged in single series, 

 in the intermaxillary and mandible, on the palatine and pterygoid bones. 

 Eye large. Pectoral fins well developed ; ventrals small, inserted at a 

 great distance from the pectorals, below or immediately behind or in 

 front of the dorsal fin ; dorsal fin short, on the hind part of the body ; 

 adipose fin small ; anal elongate, occupying the end of the tail ; caudal 

 emarginate. Gill opening very wide, the outer branchial arch beset 

 with short, spine-like gill rakers; pseudobranchise well developed; 

 branchiostegals 7. Air bladder none. Pyloric appendages none, (napa, 

 near; /Wjf, scale; scales on side.) 



899. PARALEPIS COREGONOIDES, Risso. 



Head 4 ; depth 12 ; eye 5. D. 10 ; A. 23 ; P. 13 ; V. 9. Body elongate. 

 Head compressed. Snout long, conical ; cleft of mouth moderate ; max- 

 illary rod-like, adherent to premaxillary. Teeth in a single row in the 

 intermaxillary, a few enlarged anteriorly; also on palatines and ptery- 

 goids. Ventral fin very short, inserted below the anterior part of the 

 dorsal. Gill openings very large, free from the isthmus; gill rakers very 

 numerous, minute. Color silvery; slightly bluish upon the back ; blackish 

 upon the belly on account of the transparency of the black peritoneum ; 

 along the lateral line there are some blackish dots ; iris silvery ; the 

 pupil blackish, silvery. Rare in the Mediterranean. The Albatross
