Figs. 317 and 318. 
Length of the snout ( according to Gunther’s figures ) about 13 — 14 % ( according to Collett 17 %) of that of 
the body, or 17 — 18 % ( according to Collett 22 %) of the breadth of the disk. Distance between each nostril 
and the tip of the snout about 14 — 16 % of the said breadth. Dorsal fins set close together, with (in the young) 
or without (in the old) interjacent aculeus. Aculei grooved , their number in the median line of the back and 
tail at least about 24 a .
