CARCHARINUS MENISORRAH. 135 



fifths of the distance from the second dorsal. Second dorsal and anal much 

 alike in size and outlines, the anal is perhaps a trifle the farther back and the 

 more deeply excavated on the hind margin; in both fins the upper angle is 

 rounded and the hinder produced. Caudal less than one third of the total, 

 subcaudal lobe prominent, extremity pointed. 



Back brownish, yellowish to greenish, fins lighter, tipped with black, edges 

 of caudal black; lower surfaces light. 



Total length 18, snout to abdominal pores 9, snout to fifth gill aperture 4, 

 snout to mouth I5, and length of caudal 5 inches. 



Specimen described from Apiang, Kingsmills Island, collected by Andrew 

 Garrett.

Body moderate, cavity nearly half the total length; head about one fourth 

 of the total, depressed; snout obtusely pointed, rounded at the sides from the 

 eyes, preoral length three fourths of the distance from the eye to the first gill 

 aperture. Nostrils little nearer to the mouth than to the end of the snout. 

 Width of mouth little more than length of snout, length of mouth equal two thirds 

 of the width ; sides of mouth nearly straight from the angle to the sharp curves 

 near the symphyses. Labial folds in the angle, very short, upper visible and 

 extended outward. Eyes small, length of orbits one half their distance from the 

 nostrils, one fifth of that from the gill opening. Teeth with broad bases, in ii 

 rows; upper cusps broad, oblique, serrated more coarsely toward the bases, 

 with two or three rather prominent denticles just below the notch on the outer 

 side; lower cusps lanceolate, nearly erect, with minute serrations, varying with 

 age; median teeth little smaller. Gill openings half the width of the mouth. 

 Pectorals two thirds as wide as long, outer angle sharp, hind margin concave, 

 reaching behind the mid length of the base of the dorsal. Origin of dorsal above 

 the inner angle of the pectoral, fin large, base length nearly two fifths of the dis- 

 tance from the second dorsal, upper angle sharp. Second dorsal and anal about 

 equal, bases opposed, hind margins concave, outer angles blunted, ends acuminate, 

 length of bases hardly more than half their distances from the caudal. Ventrals
