6AMMARUS LOCUSTA.

possessing the powers of leaping, nor having a large 

 produced head resembling that of a locust. At the same 

 time, as we believe that Linnaeus had the animals of the 

 present species (generally distinguished by their bluish- 

 green colour) more especially in view in his various 

 notices both of G. locusta and pulew, and as almost all 

 modern carcinologists are agreed in giving the name of 

 Locusta to the present species, we shall pursue the same 

 nomenclature, reiterating our opinion that it would have 

 been simpler to have adopted the name of Saltator for 

 Talitrus locusta, and expressing our regret that Montagu, 

 who appears first to have clearly defined the present 

 species,* did not give it a distinct specific name, as 

 has indeed been done by Liljeborg, who, how^ever, 

 subsequently sunk the name G. Duebenii into that of 

 G. locusta. 



* It must be noticed tliat Montagu represents the superior antennas as 

 considerably shorter than the inferior ; this probably arose from his figure 

 having been drawn from an injured specimen, as he represents the relative 

 size of the joints of the peduncles of both antennae correctly.
