13. Dasyatis bennetti (Miiller & Henle) (?). (Plate LXV.) 
(Trygon carnea Richardson, Ichth. Chin., 197, foetus.) 
One specimen from Takao with disk fourteen inches long and thirteen inches 
wide, and tail thirty-one inches long, we refer provisionally to this species, which 
was described from Hong Kong. Front margins of pectorals converging at an angle 
of 65°; sides of the short tip of snout meeting at nearly a right angle; tail with a 
low black cutaneous fold on under side, originating under the serrated spine and 
extending backward a distance three times interorbital space; a very short fold on 
top of tail extending back of reflexed spine a distance equal to interorbital space ; 
top of tail for remainder of its length roughened by minute spine-like tubercles ; a 
median dorsal row of short but strong spines originating behind gill-cavity and 
reaching to base of serrated tail-spine ; many small tubercles on either side of this 
row anteriorly; width of mouth contained two and one-half times in space between 
anterior gill-openings; margin of nasal flap with a short fringe; color uniform 
blackish above, pale below ; tail without bands. he tail is shorter than in Dasyatis 
bennetti and the armature somewhat different. It is questionable whether this 
identification is correct and the species may be undescribed.
