extinct genera are also referred to this family. (CHIM.ERID.E, Giinther, 

 Cat., vm, 349-352). 



CHIMJERIN.S;: 

 a. Snout short, soft, not terminating in a cutaneous flap; tail not bent upward. 



b. Claspers in the male trifid; tail ending in a filament. CHIMERA, CO. 



bb. Claspers in the male bifid; tail not ending in a filament. HYDROLAGUS, 61. 



HARRIOTTIN^E: 



a<i. Snout excessively long, with leaf-like lateral expansions; dorsal spine very large; claspers 

 small, simple. HABBIOTTA, 62. 



60. CHIMERA, Linnaeus. 

 (ELEPHANT FISHES.) 



Cltirmera, LINNAEUS, Syst. Nat., Ed. x, 1758, 236, (monslrosa). 



Head somewhat compressed, the snout bluntish, protruding, fleshy, 

 not armed at tip with an appendage. Eyes very large, lateral. Teeth 

 rather strong. Lips thickish, the lower with a frenum. Lateral line 

 simple on the body, but forking anteriorly, forming several series of 

 mucous tubes on the head. Male with a club-shaped cartilaginous hook 

 on the head above the snout; this hook is curved forward and down- 

 ward, and is armed at its tip with decurved spines ; its tip fitting into a 

 depression in front of the eyes ; females without this appendage. Gill 

 opening small. Pectorals moderate; ventrals rather large, with large 

 bifid claspers in the male ; male also with rough appendages at the base 

 of the ventrals, protruding from a sheath of skin. First dorsal triangu- 

 lar, preceded by a strong spine, which is grooved behind and serrated on 

 its edges ; second dorsal and caudal fins low, often more or less notched. 

 Tail extending in the line of the axis of the body, more or less produced 

 in a filament at tip. Skin smooth. Fishes of singular appearance ; 

 mostly of the northern seas; not valned for food. (Xtpaipa, chiniaera, a 

 fabulous monster, with the head of a lion, body of a goat, and tail of a 

 serpent). 



a. First dorsal almost continuous with second; body stout; pectorals reaching posterior end 



. of ventrals. MONSTKOSA, 140. 



aa. First dorsal well separated from second ; body slender; pectorals not nearly reaching 



ventrals. AFFINIS, 141. 



140. CHIMJERA MONSTBOSA, Lmnseus. 

 (CHIMERA.) 



Tail ending in a very long rayless filament about as long as. body and 

 head. First dorsal fin close to second and subcontinuous with it, the 

 upper margin even, not notched except just in front of the low caudal 

 fin; pectoral reaching posterior extremity of ventrals. Each clasper of 

 the male with 2 long slender branches, each rather longer than snout, 

 the inner branch again divided into a simply cartilaginous styliform part, 

 and another coated with spiny membrane. Brown, marbled with lighter; 

 dorsal fins with a broad black margin. (Giinther.) Deep waters off the 

 coast of Europe ; recorded by Poey at Matanzas, Cuba, (monstrosus, 

 monstrous.) (Eu.)
