without the caudal fin ; the head is three times and three- 
quarters in the last dimension ; the first dorsal is inserted at 
an equal distance from the anterior part of the snout and the 
upper base of the caudal. 
For all the rest, the description of Modesta applies to this 
sort. 
The specimens are very numerous, but after preservation in 
spirits their colours are entirely destroyed ; the silvery band 
on each side is however very visible. The largest specimens 
are a little over two and a-half inches long. 
MUGIL OCCIDBNTALIS. 
In Dr. Gunther's very able division of this difficult genus 
this sort must be placed in the group characterised by « orbit 
with the adipose eyelid well developed ; upper lip not 
very thick; anal fin with eight soft rays; lateral line 
with forty-three or forty-four scales;" the maxillary is 
visible. ■ 
General appearance of Mugil Waigienm and the head of 
the same form ; height of the body contained four times in the 
total length of the fish to the centre of the tail ; head not quite 
as long as the height of the body, contained nearly four and 
a-half times in the same dimension; snout longer than the 
diameter „ the eye, but contained nearly four times in the 
length of the head ; the breadth of this, behind the eyes is 
contained once and a-half in the length of the head and 'the 
space between the eyes is contained a little more than twice 
m the same dimension ; the teeth are very numerous and rather 
large, for the genus, on both of the jaws ; the space extending 
behind the eye and also the adipose eyelid are covered with 
strong and numerous arched stride; the head is covered with 
scales of large size, but these become very minute towards the 
lips ; the loDgitadinal line has forty large scales, and three or 
four smaller ones near the caudal. From the transverse line that 
would pass over the centre of the eye to the root of the dorsal 
there are twenty scales; the body is very high, and its lower 
profile very convexed ; the scales number fifteen on the trans- 
it 2
