Length of head 3 to SJ, of caudal fin f)\, height of body 3j in the total length. Eyes — 

 diameter \ of length of head, nearly 1 diameter from the end of the snout, and f to 1 

 diameter apart. Lower jaw very slightly the longer. The maxilla reaches to sUghtly behind 

 the hind edge of the eye. The posterior edge of the preopercle finely serrated except in a 

 small portion of its lower part. A considerable rise from the snout to the base of the first 

 dorsal fin. Fins — first dorsal spine one-third the length of the second, which is equal to 

 the third and about 2\ in the length of the head ; second dorsal somewhat higher than 

 the first. Caudal rounded. Scales — finely ctenoid. Colours — jsale hoi-n above and below, 

 with a slight golden tinge on the opercles : caudal and ventral both having a dark hind 

 edge. A round black spot at the root of the caudal fin. 



Hahitat. — Col. Tickell procured two examples at Akyab (see figure 4'2 inches long, 

 " scale 10/16," p. 215, MSS.) and it seems to be identical with Cantor's fish.

Length of head 3? to 4, of caudal fin 7, height of body 3i in the total length. Eyes — 

 diameter 2\ to 3i in the length of the head, 1^ diameters from the end of the snout, and 

 1 apart. The maxilla reaches nearly to beneath the front edge of the eye. Vertical limb 

 of preopercle serrated. Fins — dorsal spines slightly higher than the rays, the second to 

 the fourth being of about the same length, and the longest in the fin, while each is about 

 equal to one-third of the height of the body ; second anal spine the longest and strongest. 

 Scales — ctenoid. Colours — silvery with horizontal grayish or brownish bands, the upper 

 of which are wider than the ground colour, these bands unite anteriorly over the nape 

 and snout, while the upper ones end posteriorly at the base of the dorsal fin. Fins 

 yellowish, the dorsal, caudal and anal with some dark bands and sjaots and dark outer 

 edges. 



A specimen 7^ inches long received from Madras through the kindness of Mr. Thurston, 

 has D —J, which is very interesting, as showing how great a variation in the number of 

 spines and rays may exist, for the usual numbers are D xflxf- 



Habitat. — From the East Coast of Africa, to Ceylon, Madras, and the Malay Archipelago 

 to 380'" : and in the British Museum to 14| inches.

This differs from the types in having one more spine and ray in the dorsal fin, or 

 D 13/22, but Mr. Thurston has lately sent me a specimen from Madras with D 12/22. Some 

 error occurred in Mr. Boulenger's description, for if " the greatest dejjth of the soft dorsal 

 equals the length of the longest spine, or seven-eighths the depth of the body," this fin 

 would be enormously developed. However, we are also informed that the longest dorsal
