GAMMARTJS 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 pulex , 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, however, 
subsequently sunk the name G. Duebenii into that of 
G. locusta. 
* It must be noticed that 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.
