LYSIANASSA LONGICORNIS. 89 



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.
