LESTRIGONUS EXULANS. 7 
We also observe that the peduncle of the second pair of 
antennz is not so decidedly truncate as in ours; but, in 
spite of these differences, which are probably due to the 
delineator, we believe that our British form is identical 
with that of Kréyer’s arctic specimen. 
The original specimen was taken by Kroyer in Green- 
land. British specimens have been sent to us from 
Carrickfergus, where they were found by Professor 
Kinahan, to whom we are indebted for the first British 
specimen; from Cumbrae, where they were obtained by 
Mr. Robertson; and they have been recently sent to us 
from Banff, where they were taken by Mr. Edward. 
The resemblance between this species and L. Gaudi- 
chaudii from Chili is very close, but the two species can 
be readily distinguished by the character of the armature 
on the hands of the first two pairs of legs.
