ICHTHYOLOGY 
the eye a little over twice and a-half in the head ; the form 
is oval, the two profiles being almost equally convex. 
The dorsal is, as usual in the genus, formed of thirteen 
spines, without the one directed forwards, and ten rays ; the 
caudal is very strongly emarginated, of sixteen long rays and 
several shorter on each side ; the anal of seven spines and 
nine rays ; the ventrals have two spines and two soft rays ; 
the first and last being spines, and the three central ones only 
rays. In one specimen, one of the pectorals has three spines 
and only two rays ; the pectorals are twice as long as the 
orbit and have fifteen rays. 
The colour is of a silvery grey, with the lower parts almost 
white ; the head and body are entirely covered with round 
white spots (which may have been blue on the living speci- 
mens) ; they are very numerous, and on an average the distance 
from centre to centre is equal to one-half the one from the 
posterior edge of the eye to the one of the preeoperculum % 
traces of these spots are also seen on the fins, which are of the 
general colour ; the rays are marbled with dark grey and 
white. 
Length six inches and a-half. 
Very common. 
Bloch's (Schneid.) description agrees well with this sort, with 
the exception of the words Cauda Carinata, but this appear- 
ance may have beeen due to the mode of preserving the 
specimen. 
Dr. Gunther thinks that Forster's fish is the same as 
Nehulosa of Quoy and Gaimard (Uranie), but this cannot be 
the case if it is, as I believe, the sort I here describe. 
MUGIL NEOCALBDONICUS. 
Height four and a-half times in the total length, or four 
times in the same without the caudal ; head equal to the 
height ; eye five times in the length of the head ; space 
between the eyes contained twice in the length of the head. 
Head very broad, rounded in front ; eye without an adipose 
membrane ; lips very thick ; the upper one as broad as two-
