152 PEKCID^. 



spicuously in length, AH are strong, with a deeply notched mem- 

 brane between, and each with a membranaceous appendage' behind at 

 the tip. The first ray is one-fourth longer than the last spine ; the 

 rays become gradually longer towards the middle of the fin, and again 

 shorter towards behind. The candalis has a moderately rounded 

 posterior margin. The analis commences a little behind the com- 

 mencement of the soft dorsal ; the third spine is rather longer, but 

 not quite so strong as the second ; the inferior margin- is slightly 

 convex, the last two rays being shorter; the distance of the aniis 

 from the anal fin is nearly equal to the length of the second anal 

 spine. The pectoralis is rounded, composed of 18 rays, and reaches 

 as far as the ventral — that is, not even to the anus. The ventralis 

 has also a convex margin, the second ray being longest ; the spine is 

 rather slender, and extends beyond the half of the fin. 



The canine teeth are not very developed, but those of the villiform 

 band are relatively strong, as well as those of the vomer and pala- 

 tine bones. 



The whole fish, except the fins and belly, is covered with more 

 or less regular, large hexagonal spots of brown coloui', separated 

 from each other by straight white lines ; five or six of these spots 

 along the base of the dorsal and the back of the tail are larger and 

 of a deeper colour. All the fins exhibit rounded, scattered, large 

 bro^vn spots, and a narrow yellowish-white edge : even the membra- 

 naceous appendages of the spines are of the latter colour. There 

 are a few brown spots only on the belly ; the ventrals have a darker 

 hue ; there are indistinct spots on the gill-membrane. 



Length of the specimen 8 inches.

External appearance labroid ; scales beneath the lateral line 

 ciliated, above and on the belly smooth. Caudalis with a rather 

 convex posterior margin. Length of the head one-third of the total ; 

 diameter of the eye not quite one-sixth of the length of the head, 

 about equalling the distance between them. Pneoperculum with 

 obsolete denticulations ; the fourth dorsal spine a little the longest. 

 Brown, -variegated with' greyish, black, and white; the vertical fins 

 with a reddish edge. (Jen.)
