SCYLLIOGALEUS QUECKETTI. 

 Scylliogaleus queckelii Boulenger, 1902, Ann. mag. nat. hist., ser. 7, 10, p. 51, pi. 4. 



Snout broad, depressed, broadly rounded across the end, twice as broad as 

 deep, in length equal distance from eye to gill opening or one and two thirds 

 times the diameter of the eye. Spiracle small, diameter about equal the distance 

 from the orbit. Nostrils near midway from mouth to end of snout; anterior 

 valves broad, reaching the mouth, narrowly separated from one another in 

 front of the symphysis. Mouth regularly curved, width much greater than the 

 preoral length of the snout, with strong labial folds nearly half as long as the jaw. 

 Teeth small, numerous, in pavement, with flattened feebly ribbed crowns. 

 First gill opening about equal length of eye, fifth two thirds as much, hindmost 

 two above the pectoral. Pectoral as long as its distance from the front of the 

 eye, reaching behind the origin of the first dorsal. Ventrals small, origins 

 equidistant from spiracle and caudal fin; claspers small, simple. Bases of 

 dorsals about half as long as the interdorsal space; first dorsal about midway 

 between bases of pectorals and those of the ventrals, hind margin deeply con- 

 cave, hind angle produced. Second dorsal similar to the first, little smaller; 

 hinder half of the base above the small anal. Base of anal about equal its 

 distance from the caudal. Tail longer than the body, compressed, slender. 

 Caudal two ninths of the total, notched below the terminal portion, angles 

 rounded. Scales acutely pointed, keeled. 



Grey above; white beneath; fins grey, caudal white edged. 



Off coast of Natal, Africa, in about 40 fathoms.
