DD. Ag. P.17. L. lat. 145-150. 1, tr. 23%. 
Canines moderate ; two rows of teeth on the sides of the lower 
jaw, those of the inner row largest. Length of the head thrice and 
three fifths or thrice and two thirds in the total; forehead very 
convex, with a depression between the nostrils ; diameter of the eye 
six or six and a half times in the length of the head; maxillary 
reaching posteriorly to the vertical of the posterior third of the eye ; 
preeoperculum finely serrated posteriorly, the denticulations stronger 
at the angle, which is rounded and not produced; upper border 
of opercle slightly sinuous ; median opercular spine nearer the lower 
than the upper, lower much further back than the latter. Depth of 
the body about four times and a half in the total length. Third and 
fourth dorsal spines longest, a little longer than the longest branched 
rays, which are about once and a half as long as the posterior spines. 
Pectorals reaching to below the sixth or seventh dorsal spine. 
Caudalis truncate, when spread out with perfectly straight posterior 
border. Dark purplish brown on the upper surfaces and fins, paler 
brown inferiorly ; body and dorsal fin with scattered subcircular

A single dry specimen, 21 inches long, isin Mr. Jayakar’s collec- 
tion ; another, 26 inches long, stuffed, likewise from Muscat, formed 
part of the collection of the late East-India Museum transferred 
to the British Museum in 1880. Except in the rather smaller 
scales, these specimens agree well with one of the types, a half skin 
from Madras, presented by Mr. Francis Day.
