margin and its posterior point about 4 in interorbital space. 

 Second dorsal small, its posterior margin nearly vertical or with- 

 out posterior point, and its origin nearer posterior basal margin 

 O'f first dorsal than end of last vertebra. Anal inserted a little 

 nearer origin of lower caudal lobe than that of ventral, or about 

 opposite first third in base of second dorsal, its lower margin 

 deeply incised, and posterior point large or about 6 in inter- 

 orbital space. Origin of upper caudal lobe begins a trifle in ad- 

 vance of lower, and its greatest width near tip, 6-/5 in its length. 

 Liower caudal lobe large and falcate, its length about ^/^ in its 

 base, and after anterior lobe width narrow to notch. Pectoral 

 'long, slender, falcate, reaching about opposite posterior basal 

 margin of first dorsal, or about ^/g to ventral, and its greatest 

 width nearly half its length. Ventral small, broad basally, its 

 depth about ''/y its length, and origin of fin a little nearer pos- 

 terior basal margin of first dorsal than origin of anal. No 

 claspers. Color of dried skin dull or rather deep sandy-gray, 

 becoming slightly paler on under surface of body, especially on 

 lower surface of head and belly. Fins all more or less tinted 

 like back, also^ upper surfaces of pectoral and ventral. Lower 

 surfaces of these fins, perhaps a trifle pale. Teeth white. Length 

 8 feet 2^ inches. Noi locality is given, but evidently, if memoi'v 

 serves correctly, this example came from off the New Jersey 

 coast, probably near the mouth of Delaware Bay. L A. Swei- 

 gart. It agrees largely with Le S.ueur's figure, which I repub- 

 lished in the Report of 1906, especially in the rather long and 

 slender falcate pectoral, which would reach to the posterior 

 basal margin of the first dorsal at least. The second dorsal is 

 shown somewhat differently, however, as it has a posterior point. 

 The anal is also larger. 



A large shark, evidently this species, was taken about 1887 at 

 Lincoln Park on the Delaware River, according to Mr. R. W. 

 Pierce. It was caught in a sturgeon-net and thought to be follow- 

 ing the sturgeon. This record is of interest, as the water at the 

 locality mentioned is tidal, and therefore only slightly brackish at 

 the most. 



One, evidently this species, reported to Mr. W. J. Fox on 

 August 15th, 1905, at Sea Isle City. They were abundant on
