both equals the horizontal diameter. In front of the lower orbit, 

 above the lip, appear two small apertures of the nostril, separated by a 

 narrow membranous septum ; the lower is oval, double the size of the 

 circular upper one, which opens under a small bony protuberance. 

 The mouth, tongue, and teeth resemble those of P. grandisquamis. 

 The greatest vertical diameter of the body, at the anterior third, is 5^ 

 in the total length. On it appear 23 series of oval scales, of which 

 the largest are \ of the length of the head ; their breadth T J 7 . The 

 radical part is marked with upwards of 46 radiating lines ; the poste- 

 rior margin with 36 to 38 very minute spines, barely perceptible to the 

 touch. A straight line between the opercle and the caudal contains 69 

 scales. The lateral line and its ramifications resemble those of P. bili- 

 neata. The fins resemble those of P. lingva. The description of Russell 

 gives 148 dorsal rays, which probably is a misprint instead of 128. 

 At all events there is a great discrepancy between the description and 

 the plate which represents 165 dorsal and 155 anal rays. The form 

 of all the fins is incorrect. At Pinang this species occurs, although 

 never in great numbers, at all seasons. It is of excellent flavour, and, 

 like Plagusia trulla, passes at European tables under the denomina- 

 tion of " Sole." 



With the exception of Plagusia grandisquamis, which was not 

 observed alive, the other species are all distinguished for their tenacity 

 of life. The fishermen at Pinang assert that some species of Pla- 

 gusia shoal at certain seasons.
