snout than angle of the mouth. Eye moderate. Teeth f g, their form as 

 in C. lamia, the upper regularly triangular, without notch, narrow in the

 teeth distinctly and evenly serrated. First dorsal beginning at a dis- 

 tance $ its own base behind the pectorals and ending a little more than 

 its base before the ventrals. Space between dorsals 2? times base of first 

 dorsal, 1 times that of second. Height of first dorsal f the depth of the 

 body ; pectoral reaching past first dorsal. Second dorsal very small, not 

 the height of the first, smaller than anal and nearly opposite it. Pec- 

 torals long and broad, reaching past base of dorsal, 5| in body. Tail 3i 

 in length. Color plain light gray. San Diego Bay and southward along 

 the Mexican coast. Very close to C. lamia, but the dorsals and pectorals 

 smaller and the first dorsal farther back. (Diminutive of lamia.)

48. CARCHARHINUS LAMIA,* (Eafinesque). 

 (CUB-SHARK; REQUIN; REQUIEM ; LAMIA.) 



Head broad, depressed; snout short and rounded, nostrils midway be- 

 tween its tip and the front of the mouth ; breadth of mouth 2 times 

 length of preoral part of snout. First dorsal very large, inserted close 

 behind the base of the pectoral, its height a little greater than the length 

 of its base, its anterior margin convex, its upper angle rounded, its pos- 

 terior border nearly straight, its lower angle pointed, its height about 

 equal to greatest depth of body ; second dorsal much smaller than first, 

 about equal to anal; pectorals at least twice as long as broad, 5 times 

 in body ; upper lobe of caudal i the total length, twice the inferior lobe. 

 Grayish, fins rarely darker at tip. L. 10 feet. Tropical parts of the At- 

 lantic ; common northward to Florida Keys, abundant in the Caribbean 

 Sea and in the Mediterranean ; a man-eating shark, notorious in warm 

 regions as a greedy scavenger about wharves. (Aa^'o, lamia, sea-monster, 

 from Aai/z6f, devouring hunger.) (Eu.)

* Carcharhinus leucos, (Valenciennes): Pectorals rather long, but shorter than in C. lamia;. first 

 dorsal with pointed angles, its anterior border not convex, and its posterior border little exca- 

 vated (Dumeril); otherwise about as in C. lamia, with which it is probably identical. West 

 Indies; Algiers. (Aev*6s, white.)
