Mr. Collie lias preserved a sketch of this species, and both his notes and those of Mr. Lay con- 
tain descriptions of it. It is “ a rounded fish, with the head depressed and the cheeks swelling. 
The scales are fine, and those of the head are scarcely perceptible. The mouth is large and slightly 
extensile: the teeth are small and slender” — C. : “they are sharp, in a single row above and 
below.” — L. “ The praoperculum is separated from the operculum by a slight fossa. The ventral fins 
are longest at the interior margin: the pectorals longest in the middle” — C.: “ the first rays of the 
dorsal are terminated by filaments: the caudal is long and pointed.” — L. 
“ The general colour is a straw-green below, and a light grass-green above, with two rather 
indistinct longitudinal bands of crimson. There are three crimson bands margined with blue and 
white on the cheeks, extending to the origin of the pectoral fins. On the upper and posterior half of 
the body are three partial cross bands of crimson edged with light green ; these are broadest at their 
lower part, which is near the lateral line : behind them is a small band, or perhaps merely a rhom- 
boidal patch. The first dorsal fin has six spines ; it is banded irregularly with crimson : the second 
is without bands, and is spotted milk-white. The ventrals are white at the root; then a crimson 
longitudinal band; then a narrow whey-white one; and the rest to the margin yellow. The caudal 
has rufous patches, and light blue spots.”— C. The colours are thus described by Mr. Lay : “ Head 
lined with marbled red and blue : body yellow, with longitudinal lines of red : four hasp -like trans- 
verse spots margined with blue: dorsal fin, the first division has wavy lines of red, the second ip 
spotted with blue.” — L. 
“ The air-bladder reaches from opposite the origin of the pectoral fins to the amts. The alimen- 
tary canal is half as long again as the body, measured from the snout to the origin of the caudal fin. 
The stomach is not distinguishable from the general canal. There are no cceca. There are a few 
pharyngeal teeth above. The inside of the mouth is entirely black.” — C. “ The tongue and pharynx 
are purple ; and there is a flat yellow membrane between the tongue and the lower row of teeth.” — L-

Lanihi of the Natives of Oahu. 
Hab. in Oceano Pacifico apud Oahu. 
A specimen of this fish, preserved in spirit, was presented by Mr. Lay to the Museum of the 
Royal College of Surgeons. From this individual, by the permission of the Board of Curators, our 
figure was taken. The colours mentioned in the specific character are derived from the notes of 
Mr. Lay. In its present state, almost deprived of scales, it still exhibits vestiges of the darker 
colours which ornamented it while recent. The margin of the dorsal and caudal fins, and the whole 
of the ventral and anal, are brown : the pectoral is free from colour. There are traces of reddish- 
brown lines passing downwards and backwards from the back, and upwards and backwards from the 
belly ; but they are generally so much obliterated as to produce only in a few places the appearance 
of diamonding. The brown lines of The head are distinctly marked: they take their origin fromAhe 
rbit: one of them passes forwards from the anterior part of the orbit, crosses the hinder lip, and
