FAMILY, III-PLEURONECTID^. 435 



cycloid on the blind side : eighteen or nineteen rows between the lateral-lines of the coloured side. Lateral- 

 lines— two on either side, the upper on the blind side ceasing in about the last fourth of the body. Colours^ 

 brown, blotched all over with darker marks : fins yellowish, with numerous black spots. 



This species differs from G. hraahijrhynchm and 0. Borneensis, each of which have only one lateral-line 

 on the bjind side. 



Habitat. — Bombay, to 14| inches in length, also Madras.

 B. vi, D. 110, V. 4, A. 88, C. 12, L. 1. 104. 



Length of head 4, height of body 3^ in the total length. Eyes — diameter 20 in the length of 

 head, 8| diameters from end of snout, and 2 apart : the upper very slightly in advance of the lower. Head 

 1/6 longer than high. Eostral hook just covers the symphysis. The maxilla extends to 1 diameter of the eye 

 behind the lower orbit : angle of the mouth just behind the middle of the length of the head. Fins — highest 

 dorsal and anp^l rays 1/6 of the height of the body. No right ventral, the left attached to the anal. Scales — 

 cycloid on both sides. Lateral-lines— two on the coloured side separated at their greatest distance by twenty-one 

 rows of scales : two lateral-lines on the blind side. Colours — brownish, with indistinct blotches on the body. 



Habitat. — Sind and Belooohistan : the specimen figured, 20 inches long, was captured at Gwadur.

Length of head 6 to 5-^, height of body 4 in the total length. Hyes — the upper slightly in advance of 

 the lower, 9 or 10 diameters in the length of head, and 3 to 3| from the end of snout. The height of the head 

 rather exceeds its length. Rostral hook just covers the symphysis of the lower jaw. The angle of the mouth 

 is in about the middle of the length of the head. Two nostrils, an open one between the orbits, and a tubular 

 one before the lower eye. Fins — a single ventral attached to the anal. Scales — ctenoid on the coloured, 

 cycloid on the blind side. Lateral-lines — two on the left side separated by fourteen or fifteen rows of scales : 

 two also on the blind side. Colours — brownish on the left side, a darkish blotch covering the opercles. 



Habitat. — Sind, seas of India to the Malay Archipelago.

Length of head 4f, height of body 3f to 4 in the total length. Hyes— in the anterior half of the head, 

 the upper slightly in advance of the lower, diameter 13 in the length of head, 4| diameters from the 

 end of snout, about 1 apart. Head as high as long. Length of the snout equals 1/3 of length of head. Angle 

 of the mouth slightly behind the posterior margin of the lower eye, and rather nearer the snout than 

 the gill-opening. Rostral hook extends to in front of symphysis of the lower jaw. Two nostrils, a patent one 

 between the eyes and' a tubular one in front of the lower eye. Fins— -no right ventral. Dorsal and anal 

 fin-rays about 1/4 of the height of the body. SeaZes— ctenoid on both sides. Lateral-lines— imo on the 

 coloured side, separated by 17 or 18 rows of scales: a single one on the blind side. CoZowrs— brown, 

 irregularly marbled with darker, the opercle sometimes with a dark blotch. 



ffaJitei.— Calcutta and Moulmein in brackish waters but within tidal reach, to the Malay Archipelago. 

 The specimen figured (life-size) was from Moulmein.

 Iniddle or end of the lower ofbit. Two nostrils, one patent between the eyes, the other tubular before the lower 

 orbit. Rostral hook just covers symphysis, i^ws— highest dorsal rays 4 in the height of the body. A single
