which it begins little in advance, hind edge less weakly concave than 

 anal, origin from first dorsal fin 314 times greater than base length of 

 second dorsal. Caudal length more than 3% in total length, termin- 

 ally truncate below^ ; front edge of falcate subcaudal 21/2 in fin. Pec- 

 toral moderate, triangular, upper edge weakly convex, lower edge 

 strongly concave; inner hind edge forms right angle, form of fin 

 rounded falcate, upper edge 3 times longer than low^er. 



Above and on sides lead color, below yellowish wdiite. Caudal 

 somewhat darker at angular tip or gray black, though without dark

It seems to me that Carcharias spenceri Ogilby is a synonym of 

 the present species. It is described with a short blunt snout, and 

 though the first dorsal is said to be inserted a little nearer to the 

 pectoral than to the ventral, it is not howeyer described as over the 

 pectoral base. Moreover, the pectoral is said to extend below or 

 beyond the end of the first dorsal. Ogilby's type was 1,220 mm. long 

 and is No. 290 in the Queensland Museum. Also an example from 

 Brisbane, 315 mm.
