fin, and its spine is as long as that of the second dorsal. The^ 

 caudal is slightly emarginate ; its peduncle is long and slender r 

 its length above being twice, and its depth less than the- 

 diameter of the eye. 



Scales. — The scales are large and finely ctenoid : there- 

 are two in advance of the first dorsal. The lateral line closely 

 follows the dorsal profile ; it does not run medially along the- 

 caudal peduncle, but falls to below the middle, where it is 

 lost at the base of the caudal rays ; its scales are branched 

 anteriorly, but become simpler on the tail. 



Colour. — The upper half of the head is dark-brown, the 

 lower portion yellow, becoming silvery on the operates : the- 

 two areas are separated by a dark horizontal bar which 

 extends from the snout through the middle of the eye to the- 

 margin of the opercle. Below this is a narrow white bar,, 

 which broadens slightly on the opercle. The body is pale- 

 brown above and silvery-yellow beneath, with a large brown 

 blotch in the middle of the depth beneath the spinous dorsal,, 

 this is split up by three narrow vertical silvery bars : a broad 

 brown band passes from the base of the anterior dorsal rays 

 obliquely forward to the space in front of the anal : the 

 dorsals are dusky, the other fins colourless. 



Length. — 88 mm. Four specimens obtained. 



These specimens differ from typical examples of the genus 

 Archamia only in having seven in place of six spines in the 

 first dorsal fin. They apparently approach the characters of 

 A. zosterophorus, Bleeker,( 4) but in that species the white 

 facial band and the anterior body-blotch are absent, and the* 

 complete band includes the whole base of the second dorsal.
