Head short, about two elevenths of the total length, rather broad and de- 

 pressed; snout short, twice as long as the mouth. Nostrils small, nearer to the 

 teeth than to the end of the snout, with a deep groove to the mouth; anterior 

 valves without cirri, reaching the mouth, forming a broad angular lip with a 

 narrow median, presymphyseal, attachment; no posterior nasal valves. Mouth 

 wide, length one third of the width, with moderate labial valves around the 

 angles. Eye small; orbit elongate, narrow; lower lid without a fold, opaque, 

 closing against the edge of the upper lid. Spiracle small, close behind the eye. 

 Gill openings moderate, equal the width of a narial valve, hindmost smallest 

 and above the pectoral. Outer angles of fins rounded. Pectorals large, broad, 

 hardly reaching halfway to the ventrals. Dorsals small, equal, separated by 

 more than twice the length of the dorsal base; anterior dorsal origin behind the 

 ends of the ventral bases; second dorsal origin at the end of the base of the anal; 

 inner angles not produced. Anal one third larger than the dorsals, narrow, 

 elongate. Subcaudal short, narrow, tapering forward and backward. Scales 

 small, with a strong carinate median cusp and with shorter lateral cusps. 



Light yellowish brown, with broad irregular, dark-edged, transverse bands 

 of darker on the back, and with small reticulations of brown or small spots of 

 yellowish on back and fins. One band crosses the hind part of the orbit, another 

 the hindmost gill aperture, another is at the ends of the pectorals, and one each 

 passes through the dorsals and the caudal pedicel. Lower surfaces lighter, 

 unspotted. Description from a specimen of 19 inches, of which the length from 

 the snout to the abdominal pores was eight inches. 



Off the coasts of South Africa. 



Proscyllium. 



Proscyllium Hilgendorf, 1904, Sitzb. Ges. nat. freunde Berlin, p. 39. 



Head and snout elongate. Anterior nasal valves separate from one another 

 and from the mouth. Mouth large. Pectorals small. Dorsals small, inner 

 angle produced; first dorsal in part forward of the ventrals. Anal long, distant 

 from the subcaudal.
