 upwards, sHvery below the lateral-liue, where however there are similar lines but very faint. _

S^er-fishes. • 



BrancUostegah seven : pseudohramchicB. Body somewhtt elongated. Glefi of mouth deep. Teeth large and 

 strong m the jaws : mllifonn on vomer, palatines, and tongue. Two dorsal Jms, the first with feeble spvnes, extending 

 to the commeiicemmt of the second, more rays in the second dorsal than spines in the first ; seven or morefimMs behind 

 the second dorsal and anal fins. Scales, when present, rudimentary. A slight keel on either side of the caudal lobes. 

 Ai/r-vessel present. 



The seer-fishes of India, when of the proper size, are considered as amongst the most delicate for eating 

 of the marine forms. If small, as under a foot in length, they are dry, resembling Trachytiatus and Ghorinemus: 

 from li to 2i feet iu length they are at their primest size, above this they become coarse.

Length of head 6^ to 6, of caudal 3f to 4, height of body 5 in the total length. Hyes — diameter 1/5 

 of length of head, Ij diameters from end of snout, and also apart. Greatest width of head equals 1/2, and its 

 height equals 4/5 of its entire length. Maxilla reaches to below the hind edge of the eye. Preopercle 

 emarginate along its vertical border, with the lower Hmb almost as long as the hind one. Teeth — conical and 

 rather compressed, from 16 to 20 in either jaw, those in the lower much the larger : vomerine patch anteriorly 

 rounded, in a band along the palatines. FiAns — first dorsal spines weak, second dorsal anteriorly equals 3/4 of 

 the height of the body below it, there are six unarticulated rays at its commencement hidden in the skin, the 

 anal which commences on a vertical line below its centre is similar to it but not so high. Pectoral as long as 

 the head behind the middle of the eye. Ventrals equal 1^ diameters of the eye in length. Caudal with deeply 

 pointed lobes. Lateral-line — containing about 200 plate-hke rounded scales, each having a simple tube, is 

 straight until it arrives opposite the end or middle of the base of the second dorsal, where it curves to below 

 the third finlet and then becomes rather wavy, its central keel well-developed. Colours — bluish above becoming 

 silvery on the side and below. After death the sides assume a dark hue and have neither bands or spots. First 

 dorsal black : second dorsal and also anal with dark bases : pectoral with a light outer edge, tips of caudal dark. 



Sabitat. — Seas of India. The specimen figured (from Bombay) is l'^ inches in length, but it attains a 

 much larger size.
