body, all of them above the lateral line, but only four on the trunk of the tail; one of them 
below the lateral line. The, discs of the scales are more silvery on the sides, and beneath the 
lateral line they are faintly shaded at the base with pearl-gray, and have neither spots nor 
coloured borders. Head greenish above, glossed with crimson on the snout, temples and oper- 
culum, and silvery with yellow shadings beneath. Dorsal yellowish-gray. Pectorals greenish 
at the base and cream-yellow elsewhere. Anal and ventrals pale cream-yellow with ochraceous 
rays. Caudal dark blackish-gray. Iris silvery with a patch of orpiment-orange.

The shading of the drawing seems to indicate that the belly of this fish is acute from the 
middle of the pectorals to the anus. Its back is very flatly arched, the nearly horizontal face 
forming part of the curve, which is much inferior in convexity to the belly. The height of 
the body is about equal to the seventh of the length, of which the head forms less than an 
eighth part. The scales seem to be small and delicate, and the lateral line descends at its 
commencement in a short arc to the lower quarter of the height, and then runs horizontally 
from the last quarter of the anus, where it rises parallel to the curve of the attachment of the 
anal fin, and again resumes its horizontal direction when it has reached the middle of the tail. 
The dorsal commences a little behind the front of the ventrals or in the middle of the length, 
caudal excluded. It is taller than the anal, and equals it in the length of its base. The 
~ caudal is forked. 
The very silvery scales are shaded at the bases with leek-green on the back and light pearl- 
gray on the belly. The fins are pale mountain-green, transparent and without spots, except 
the pectoral, which is asparagus-green with a blackish spot on its inferior angle, near the base. 
There are some greenish-yellow shadings on the head.

This figure has considerable resemblance to L. macherioides, and the curvature of the lateral 
line is the same, but it has a straighter back, a more convex belly, higher body, and a longer 
and lower anal. The head is equally slender, the snout and lower jaw more acute, and the 
eye larger. The triangular and acute dorsal commences opposite to the axilla of the ven- 
trals. The pectorals are very acute and the anal reaches near to the caudal. The rays 
shown in Mr. Reeves’s figure are D. 8; A. 15. In the ‘ Descr. of Animals’ they are noted 
as D. 8; A. 14; C.18; P. 15; V.8. About thirty-four scales exist in a longitudinal row, 
and there are ten or eleven rows in the height. 
Colour of the back pale and pure wood-brown with seven pale crimson, longitudinal streaks 
in the whole height, corresponding with the rows of scales. Below the middle height the 
scales are shaded with pearl-gray. ‘The caudal is pistachio-green, the dorsal, anal and pec- 
torals ash-gray, with a blotch of rich carmine on the base and first ray of the dorsal, and a 
slight blush of the same on the base of the ventrals, the first anal ray, and all the pectoral rays.

»A-specimen deposited in the British Museum by John Reeves, Esq. measures fourteen 
inches in length. . Itis fusiform, with a thickish tail and rather acute snout, perfectly well 
represented by Mr. Reeves’s drawing. The stoutish upper jaw projects beyond the lower 
one; and cuives slightly over it, but'the rictus of the mouth is not large and does not reach 
_ backwards to the nostrils. Operculum finely streaked. The eye is rather above the middle 
height of the head, and the furrowed preorbitar and temporal extremity of the suborbitar 
tubes rise above its level, The maxillary touches the corner of the mouth, but scarcely forms *
