 there is always the anticipation that there may be peculiar 

 insular forms in any unexplored island to stimulate the

On account of the high seas and the dangerous coast, it was only Avith 

 great difficulty that we effected a landing, and it was only possible to remain 

 ashore for a few hours. Hence the small collections ! Gough Island un-

The purpose of these notes is to record the results of 

 an examination of Norway lobsters, in which the following 

 three points have been specifically dealt with: — 



1. The relative size of males and females.
