Po-tang-dah, Andam. 



B. vi, D. V, P. 12, V. 1/5, A. f , C. 17, L. 1. 46-47, L. tr. 5^/16, Ceec. pyl. 3. 



Length of head 3/11, of caudal 2/11, height of hody 2/7 of the total length, ^y/es— diameter 3| to 1/4 

 in length of head, rather above 2 diameters from end of snout, and 1 apart. Height of head nearly equals it.s 

 length. Snout rather elongated and pointed, having a slight swelling above the anterior superior edge of the 

 eye. The maxilla reaches to below the front nostril. Teeth — canines in front of the villiform bands in both 

 jaws, and of moderate size ; the first four in the lateral row conically obtuse, whilst the hind ones are large and 

 rounded. Fins — dorsal spines weak, iacreasing in length to the fourth which equals one-third of that of the 

 body below it, or 2| in the length of the head, and is about equal to the length of the rays. Pectoral about 

 equal in length to the head : ventral just reaches the anal spines, which are of moderate strength, the third 

 being slightly the longest : caudal forked. The height of the free portion of the tail at its commencement 

 equals its length. Scales — from 5|^ to 4 entire and 2 half rows between the lateral-Hue and the sixth dorsal 

 spine. Colours — greenish-olive, with an oblong blackish blotch below the lateral-line opposite the middle of 

 the dorsal fin. 



Klunzinger gives only 4i rows of scales above the lateral-line ; if such is not a typographical error his 

 fish cannot be this species. 



Habitat. — Red Sea, through those of India to the Malay Archipelago. 



Genus, 4 — Sphjieodon, Bupp. 



Ghrysophrys, sp. Cuv. and Val. : Pagrus, sp. Bleeker. 



Branchiostegals six : pseudobranchire. Jaws with conical canines anteriorly and a single row of molars 

 laterally. A single dorsal fin with ten spines, recevoahle into a groove at their base : three anal spines. Scales of 

 ■luodemte size extending on to the cheehs. Pyloric appendages few. 



Geographical distribution. — Red Sea, throughout those of India to the Malay Archipelago.
