ICHTHYOLOGY 
the anal is of the last colour, as are also the ventrals ; the 
pectorals are obscure. 
The total length of the specimen is about six inches and a 
half. 
ORISTICEPS AMjENUS. 
This sort is very nearly allied to Gr. Multifenestratus, and 
has the same numerous transparent spots on the dorsal and 
anal, of which the general colour forms a sort of trellis 
work, so remarkable in that sort ; but the body is shorter, 
its height being here contained four and two-thirds times 
in the total length, when in Multifenestratus it is over 
five times and a half. The operculum, which is smooth in 
the last-mentioned sort, is strongly striated in Amaenus. The 
general colour is also different, the dried specimen showing 
still the beautiful orange-red which adorned it in the fresh 
state. 
The lengtli of the specimen is eight inches. 
Nota. — The length of Fenestratus is erroneously stated in 
my description of it ("Proceedings, 1872," p. 131). The 
present measurement is the correct one. 
CRISTICBPS HOWITTII. 
I have seen several specimens of this sort, but in a dried 
state. The height of the body is contained a little more than 
five times in the total length ; the head is four and one-third 
times in the same, and the eye four times and two-thirds in 
the length of the head ; the lower jaw is longer than the 
other, no scales. The first dorsal is placed over the centre of 
the orbit ; it is formed of three rays, the first of which is 
strongly prolongated ; the second dorsal is high, particularly 
at its posterior part ; it is formed of thirty-five rays. The 
caudal is lanceolate and is very long, and is contained four 
times and two-thirds in the total length ; the anal of the 
same form as the second dorsal, of twenty-seven rays ; the 
ventrals of two rays, one bifide ; the pectorals long, having 
more than two-thirds the length of the head, of eleven rays, 
the centre ones being much larger than the side ones.
