Depth 614 to subcaudal origin; head 514, width about 11/4- Snout 

 2% in head; eye 4, 1% in snout; mouth width about 2% in head, 

 length about 21/^ its width, which much greater than preoral length ; 

 long labial folds nearly half length of each jaw-; teeth numerous, 

 38 rows below, with feebly ribbed crowns ; nostrils nearer mouth than 

 snout end, wide front valves reach mouth, internarial equals preoral ; 

 interorbital low. First gill opening equals eye, last 2 shortest and 

 little closer above pectoral. 



Scales keeled, acutely pointed. 



First dorsal origin little nearer pectoral than ventral origin, front 

 edge equals head ; front edge of second dorsal 1% ; and origin oppo- 

 site first fourth of anal base; anal smaller, front edge 1% in head; 

 least depth of caudal peduncle 3% ; pectoral IjJ^, reaches little be- 

 yond first dorsal origin; ventral length li^; caudal 31^ in rest of 

 body. 



Uniform gray above, white beneath. Fins gray, caudal edged with 

 white. Length 340 mm. (Boulenger.) 



Natal, South Africa. 



Family SPHYRNIDAE 



Head with remarkable lateral expansions of skull across frontal 

 region, thus eyes moved outward. Eyes with well-developed nictitat- 

 ing membranes. Mouth crescentic, inferior. Teeth alike in tw^o 

 jaws, compressed, oblique, each notched on outside near base and 

 labial folds rudimentary. Nostrils distinct from one another and 

 from mouth. Last gill opening over pectoral base. No spiracles. 

 First dorsal large, in advance of ventrals though nearer pectorals. 

 Second dorsal and anal small. Caudal root with pit, single notch 

 toward fin tip. Pectorals large. 



A very distinct group of sharks, greatly suggestive of typical 

 Galeorhinidae in many ways, such as Scoliodon., Eulamia^ etc., differ- 

 ing in the greatly expanded lateral lobes on each side of the head.
