LYS1ANASSA LONGICORNIS,

our attention was drawn to a species resembling this in 
Lucas’ Description of Crustacea taken on the shores of 
Algeria ; since which time we have had the opportunity, 
through the kindness of M. Lucas (who permitted us 
to examine the Crustacea in his private collection), of 
identifying the present specimen with that taken by 
him on the northern coast of Africa. 
Among the Crustacea forwarded to us by that obliging 
and indefatigable naturalist, Mr. Edward, of Banff, we 
have found a portion of an animal of this species from 
the Moray Frith. We are also indebted to Professor 
Kinahan, of Dublin, for several specimens from Dublin 
Bay. All the specimens from the last-named locality 
have the lower antennae shorter than that given in our 
description and figure of the species, and do not possess 
the calceola attached to the same appendage — circum- 
stances which have induced us to conclude that these 
were female specimens.
