Head depressed ; snout long, narrowed forward, rounded at the end. Length 

 of snout from the mouth nearly equal to the distance from the eye to the first 

 gill opening. Nostrils nearer to the end of the snout than to the corners of the 

 mouth. Mouth arched, wider than long; labial folds short, on the lower jaws, 

 not on the upper. Teeth in || rows; median tooth of upper jaws erect, not 

 small; the two symphyseal teeth of the lower jaws hardly smaller than the others. 

 Pectorals longer than broad, rather sharp angled, reaching the dorsal. Base of 

 the first dorsal nearer to the ventrals than to the bases of the pectorals. Origin 

 of the second dorsal above the end of the anal base, length of the dorsal base 

 about one third of its distance from the caudal; base of anal about twice as long, 

 equal half of its distance from the subcaudal or hardly half of its distance from 

 the bases of the ventrals. Ventrals smaller than the anal. Posterior margins 

 of pectorals, first dorsal and anal concave. 



Back brownish ; lower surfaces and margins of pectorals whitish. 



India and East Indies. 



Scoliodon dumerilii. 



Carcharias (Scoliodon) dumerilii Bleeker, 1856, Act. Soc. sci. Ind. Neerl., I, Amboina, p. 70; Dumeril, 

 1865, Elasm., p. 344; Gunth., 1870, Cat. fishes Brit, mus., 8, p. 359. 



Body elongate, compressed. Head much broader than deep, length of 

 snout twice that of the mouth, three times the diameter of the eye. Nostrils 

 midway from the angles of the mouth to the end of the snout. Labial folds 

 short, in the angles. Teeth not serrated; median upper tooth small, erect. 

 Pectorals much longer than wide, reaching the dorsal, concave on the hind 

 border, distant from the eye about the length of the snout from the mouth. 

 First dorsal little closer to ventrals than to pectorals. Length of anal base about 

 one third of its distance from the ventrals. Caudal pointed. 



Distinguished from S. walbeehmi by length of snout, position of nostrils, short- 

 ness of labial folds, position of the first dorsal, length of pectorals, and colors. 



Back brown ; pectorals black narrowly bordered with white. 



Amboina.
