Head broader than high, flattened below; snout broadly rounded forward. 

 Nostrils large, much nearer to the mouth than to the end of the snout; anterior 

 valve broad, with a somewhat produced and rounded lobe. Mouth large, width 

 httle less than length of snout, length less than length of orbit; labial folds nearly 

 half the length of the jaws, upper fold longer. Teeth small, smooth, convex on 

 the crown, without notches on the edges, without a sharp cusp or denticle. Eye 

 rather large, pupil horizontally elongate, orbit nearly twice the preoral length. 

 Spiracles small, distant from the eye about one fourth of the length of the orbit. 

 Gill openings wide, greatest width one fourth less than length of orbit. Pectorals 

 large, width about two thirds of the length, outer angle pointed, inner rounded, 

 hind margin little concave. Dorsal large, origin a short distance behind the end 

 of the pectoral base, much in advance of the hind margin of the pectoral, length 

 of base greater than height, equal half the distance from the second dorsal; pro- 

 duced end of fin not reaching a vertical from the ventrals. Ventrals large, nearer 

 to the first dorsal than to the second, hind margin little concave. Second dorsal 

 more than half as large as the first, middle of base above origin of anal. Anal 

 much smaller than second dorsal, base and acuminate extremity extending a 

 short distance behind those of that fin, base about three fourths of its distance 

 from the caudal. Caudal moderate, more than one fifth of the total length, sub- 

 caudal lobe feeble. Eggs large, not supplemented by a placental attachment. 



Greyish to brownish grey, in most cases with few to many spots of white 

 along the sides above the lateral line and with white hind borders to the fins; 

 white below. 



Total length 30, snout to abdominal pores 14, snout to fifth gill opening, 4|,
