BY C. HEDLEY. 91 



Type in British Museum. 



Hab. — Not South Cape Island (Rolls), but Seymour Bay, 

 Fergusson Island (Hedley). As Rolls and Goldie landed in 

 Seymour Bay, I have no doubt that they collected the type exactly 

 where I found the species several years afterwards. I make the 

 above correction with the more confidence since I have searched 

 South Cape in vain for it. It is interesting to note that both G. 

 rollsianus and P. brazierve, which I also gathered at Seymour Bay, 

 find their allies among the distant Louisiades and not with the 

 molluscs of the nearer mainland. 



Animal slender ; colour entirely white in one specimen, bluish- 

 white in another ; tentacles long, slender, tapering, bases wide 

 apart. Observed crawling upon the trunks of trees.
