being equal to one-ninth, and the finless tip of the tail toa tenth. The lateral line runs about 
two-fifths of the height from the edge of the belly, and three from the summit of the back. 
The distance between the tip of the snout and fore-edge of the orbit is one-third of the length of 
the head. There are upwards of fifteen very faint streaks on the preorbitar. The margin 
of the upper jaw is curved at the junction of the intermaxillary and maxillary, and the former 
bone carries ten small teeth, exclusive of the canine one, while the latter is armed by only seven, 
which are somewhat larger. The maxillary can retire wholly under the preorbitar, and scarcely 
reaches the orbit. The canine teeth have a thin posterior edge at the tip, which ends 
abruptly, producing a barb which is too minute to be seen ,by the naked eye, and not to be 
compared with the acute arrow-headed tooth of 7’r. lepturus, as represented in Bl. Schn. t. 
100. The small teeth are enlarged by similar edges at the base, the tips being narrower and 
roundish. Top of the head flattish without an acute ridge. The spines on the under edge 
of the tail are so minute that they cannot be reckoned even by aid of a lens in a plump per- 
fect specimen. In one alittle decayed, they are seen to be the clear pungent tips of the inter- 
spinous bones, with which they agree in number, amounting to about 110 or more. There 
are two spinous points on the hinder edge of the very small anus. Length, 14°15 inches. 
From snout to anus, 4:09. Length of head 1°55, of point of tail beyond the dorsal fin 1°40. 
Height of body 1 inch.

Mr. Reeves’s figure shows the bands as described in the ‘ Histoire des Poissons,’ but not 
the white corners of the caudal. Neither the one nor the other are expressed in the plate of 
the ‘ Fauna Japonica.’

Ihave been unable to refer this figure to any described species. It has nearly the proportions 
and general form of Ch. commersonianus, but it wants the spots, and has a more obtuse snout 
and larger ventrals. The profile is incurved over the eye which renders the snout gibbous. 
The eye is large. The lateral line makes a small arch at its commencement and is then waved 
twice slightly up and down under the spinous dorsal, the remainder being quite straight from 
the third or fourth soft ray to the caudal. The scales appear to be very minute, deeply im- 
bedded in the satiny skin and not close to each other. Most of the fish is brightly silvery, 
but the back is deep lavender-purple, which fades away before it reaches the lateral line. The 
snout and temples are shaded with the same, and there is a large blackish-purple patch on 
the upper and posterior parts of the operculum. The supra-scapular region is brightly sil- 
very, as is also the iris, which has a yellow ring round it. The pectorals are cream-yellow, 
Shaded at the base with brown. The teeth are shown small, setaceous, and thickly set on 
both jaws. Length of figure 16 inches.

__ This figure has much the general form of Bloch’s aculeatus, but differs in the mouth being 
cleft beyond the middle of the head, and consequently passing the eye considerably. Its 
»snout is also more gibbous. at the nostrils. It may possibly be the young of some of the 
‘Spotted species. In the size of its mouth it appears to coincide with exoletus, but the lateral 
mpeirants the undulations which are noticed in the description which is given of that fish in 
the ‘ Histoire des Poissons.’ The cleft of its mouth is larger than that of leucophthalmus. The 
Jateral line makes an angle over the pectoral and afterwards continues straight without any 
‘undulation whatever. In the figure the back is illuminated by a clouded mixture of delicate 
‘sienna-yellow, having metallic lustre and pale siskin-green, the parts below the lateral line
