HYPOPRION MACLOTI. 121 



small, pupil vertical. Pectorals broad, rather sharp, reaching behind the origin 

 of the dorsal, hind margin concave. 



Origin of first dorsal nearly midway from snoul to caudal pit, end above 

 origins of ventrals, base above the middle of the space between pectorals and 

 ventrals, upper angle sharp, hinder produced. Second dorsal nearly as large as 

 the first, above the anal, acuminate extremity not reaching the caudal pit. The 

 dorsals are large and nearly equal in size. Ventrals and anal smaller than the 

 second dorsal; anal below the second dorsal with origin a little in front. Caudal 

 medium with a strong lower lobe. 



Uniform greyish olive or olivaceous grey, tips of fins slightly darkened. 



A specimen taken by Prof. Geo. B. Shattuck at the Bahamas contained 

 nineteen young each about eighteen inches in length. In a specimen secured 

 by Mrs. Celeste N. Willard at Pensacola, Florida, the rows of teeth are §|. 

 Poey's types were from Cuba.

Carcharias (Hypoprion) macloti Muller & Henle, 1841, Plagios., p. 34, pi. 10; Dumehil, 1865, Elasm., 

 p. 350; Gunth., 1870, Cat. fishes Brit, mus., 8, p. 362. 



Body moderately stout; head long, one fourth of the total, tapering. Snout 

 elongate, pointed. Nostrils much nearer to the mouth than to the end of the 

 snout; valve with a small pointed lobe. Eye moderate, length of orbit nearly 

 equal distance from nostril. Mouth large, greatly arched, its width equal two 

 thirds of the snout, or one and one third times the length; labial folds at the 

 angles, not extended on the jaws. Teeth in 27 rows, slightly oblique; upper 

 denticulated on the base at each side of a rather narrow cusp, symphyseal rows 

 of smaller teeth; lower cusps narrower, bases smooth, median tooth small. 

 Pectoral moderate, falciform, two thirds as wide as long, angles slightly blunted. 

 Dorsal origin above the inner end of the pectoral, hinder angle acuminate, nearly 

 reaching a vertical from the ventrals. Anal small, origin forward of that of the 

 second dorsal, hinder margin concave, hind angle produced. Second dorsal 

 smaller than the anal, origin above the hinder third of the base of the latter, base 

 distant from that of the first dorsal about one fourth of the total length, or about 

 the length of the caudal, acuminate extremity not quite reaching the caudal pit. 

 Caudal equal length of head to the fifth gill opening; subcaudal lobe prominent, 

 sharp. Scales minute, three to five keels.
