Length of head f, of pectoral \ of total length. Height of body nearly f of total length. 



Eyes — Diameter nearly \ of length of head, rather more than 1 diameter from end of snout. 



Maxilla hardly extends as far as anterior margin of orbit, cleft of mouth narrow. Preopercle, 

 vertical limb emarginate, angle not projecting. 



Fins — Dorsal spines strong, interspinous membrane notched, the fourth spine the longest 

 and three-fourths of length of head. Second anal spine much the longest and strongest. Caudal 

 truncated. 



Colours— Body silvery, slightly tinged with brown on the back, and with six longitudinal 

 golden lines. The membrane of the spinous dorsal brownish, with a brown spot between 

 each of the soft rays. The caudal blackish brown. The other fins are of a bright yellow, as is 

 also the iris : the pectorals are pale. 



Grows to six inches in length.

Form closely resembles the P. kasta, only slightly more elevated, the vertical limb of the 

 preopercle more rectangular, and the scales smaller. The second anal spine excessively thick, 

 striated on its anterior surface, in length rather more than half the vertical diameter of the 

 body above it, and comparatively shorter than in the P. hasta. 



Air vessel elongated, nearly one-third of the total length, swelling in the middle, and 

 terminating in a point ; the anterior extremity blunt, and appeals to have on each side a pointed 

 process a little less than one-third of the length of the vessel itself, which is restricted at the 

 origin of the lateral processes. 



Colours — Upper surface of head and back pale blackish olive ; cheeks, opercles and sides 

 silvery grey, with blue and golden reflections ; abdomen yellowish silvery ; most of the scales 

 have the edges minutely dotted with brown, and those above the lateral line a pale brown 

 spot at the root, forming six or seven indistinct parallel lines ; fins pale yellowish ; membrane of 

 dorsal minutely dotted with brown, between the spines one or two series of large clouded brown 

 spots, and a single series of smaller between the rays ; margins of dorsal and caudal blackish ; 

 the membrane of the latter and of the anal slightly dotted with brown. Iris golden. (Cantor.) 



Good eating, air vessel very thin, and consequently furnishes isinglass of but little value. 

 Grows to two feet in length. 



Habitat — Seas of India and Malaysia ; said occasionally to enter fresh water.
