crest that has one distinct rostral tooth and posteriorly a 
rudimentary point. 
Length about 3 inches. 
Taken in South Indian Ocean at a depth of about 2100 
fathoms. 
Genus Acrrss, Edwards. 
I have not had the advantage of examining critically any 
‘species of this genus; but it appears to differ from Sergestes 
in the absence of the two posterior pairs of pereiopoda ; but 
whether the third and fourth pairs terminate in minute chele, 
as in Sergestes, I am not able to determine. Milne-Edwards 
has figured and described them, as he has those of Sergestes, 
as being filiform, which they appear to be by the assistance 
of an ordinary lens; but more critical examination shows that 
they are minutely chelate, as determined by Kréyer. 
The branchial apparatus, so far as I am aware, has not been 
examined by any one. 
Acetes indicus, Edwards. 
IT am not aware that this animal has been noticed since 
described by M. Milne-Edwards in 1829 at the Académie des © 
Sciences de Paris; yet it must be very abundant in our seas, 
and Sir Walter Elliot notes on his collection made at Madras 
that “avery large Dicerobalis eroogoodoo was taken at Waltair 
in 1825, 21 feet in length and 25 broad. Its stomach was 
filled with myriads of this little crustacean, which was carried 
away in basketfuls by the fishermen, and thousands were left 
scattered on the shore.” 
Information such as this appears to be suggestive of the 
desirability of surveying the ocean in mid water as well as at 
its bottom and surface.
