ICHTHYOLOGY 
The anal has two feeble spines and eleven rays; it does not, 
nor does the dorsal, attain the base of the caudal ; the ventrals 
are almost as large as the pectorals, and being inserted much 
further back, extend considerably behind them ; they are 
united at the base, and have a slender spine and four rays ; 
the pectorals are rounded and formed of thirteen rays. 
The colour is (after having been in liquor) of a fleshy pink, 
with the sides of the head brilliant ; there is no trace of 
coloured stripes on the head ; the fins are yellow, with a black 
tinge on the anterior and posterior parts of the dorsal. The 
caudal has four transverse black bands ; the anal a broad faint 
black stripe on the middle of its height, and the second half 
of the ventrals is of the same colour. 
Total length six inches. 
PHYLLOPTERYX ELONGATUS. 
Very much like Foliatus, and at first I thought it was a 
variety of it, but I have seen four specimens, and they all agree 
together ; the following are the differential characters : gener- 
ally smaller, the largest adult female being only nine inches long 
(the same in Foliatus about fifteen) ; the spine on each side of 
the snout is lateral and not superior. The body is much more 
elongate; in the female its greatest height is contained twice 
in the length of the snout up to the anterior edge of the eye, 
and in the male three times. The lower side of the body only 
presents a pair of ventral processes in both sexes, when in 
Foliatus the female at least has another, without foliated 
appendages, under the anus. The foliated appendages of the 
back are much shorter and broader and of an oval form, they 
are not generally much longer than the processes itself. 
The colour of the dried specimens is much lighter ; on 
those in liquor I find that the end of the muzzle, the lower 
parts of the head and body, and the sides of the tail, are white ; 
the upper parts of the snout, head, and body, are of a lilac 
colour, covered with numerous round white spots. The 
foliated appendages and the end of the tail are black. 
On the living specimens, Mr. Waterhouse says, that the 
colour is orange, with granular dark blue spots and markings
