LESTRIGONUS EXULANS. 7 



We also observe that the peduncle of the second pair of 

 antennae 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 Kioyer^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.
