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 Kroyer'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.
