angle rounded. Dorsal VI, I 9. Anal II 11. Dorsal spines feeble, 

 the second or the second and third the highest ; soft dorsal and anal 

 with slightly cmarginate outer edges ; pectoral extending beyond origin 

 of anal, ventrals to the vent ; caudal notched, scales deciduous. Caudal 

 peduncle twice as long as deep. A blackish line along the middle of 

 the side from the operculum to below the end of the soft dorsal ; fins 

 immaculate. 



Length, to base of caudal, -11 mm. 



Nine specimens from Karachi. 



Very closely allied to A. gracilis (Blkr.), which has II 12-13 anal 

 rays, the first dorsal spine the highest, and the dark lateral stripe ex- 

 tending from the snout to the caudal. 



ClRRHITIOHTHYS CALLIURUS (PI. II, fig. 3). 



Depth of body about 2| times in the length (without caudal), length 

 of head 3^-3^ times. Snout as long as the eye, the diameter of which 

 is of times in the length of head, and a little greater than the inter- 

 orbital width. Maxillary extending to below anterior \ of eye ; prseorbital 

 entire, its depth § the diameter of eye ; praoperculum strongly serrated ; 

 supraclavicle serrated. Dorsal X 12, the fifth or sixth spine the longest, 

 more than \ the length of head ; the first soft ray produced, reaching 

 the caudal when laid back. Anal III 6, the second spine the longest, 

 as long as longest soft rays and nearly g the length of head. Pectoral 

 with 7 simple rays, extending a little beyond origin of anal ; ventral 

 extending to origin of anal ; caudal truncate or slightly emarginate. 

 11-13 scales in a longitudinal series ; 4-4| between first dorsal spine 

 and lateral line ; vertical fins covered with scales in their basal halves. 

 Brownish, marbled with darker, the soft dorsal and anal and the caudal 

 peduncle almost blackish ; caudal fin pale yellowish, sharply separated 

 from the dark colour of the caudal peduncle, with a pink tinge at the 

 base, a dark posterior margin and a few dark spots. 



Length, to base of caudal, 85 mm. 



Two specimens from Muscat, 15-30 fathom^. 



Platycbphalus nigripinnis (PI. I, fig. 2). 



Depth of body 6 times in the length (without caudal), length of head 

 3 times. Snout scarcely longer than the eye, the diameter of which is 

 4| times in the length- of head, interorbital width 1\ times, breadth of 

 head 1? times. Maxillary extending to below anterior ^of eye. Upper 

 surface of head flatfish, with ridges not or very feebly seriated and not
