Common Hermit-Crab, Eupagurus bernhardus (L), associated 



with Suberites domuncula. 



The Hermit-Crab, which is usually found associated with 



the Sponge (Suberites domuncula), is E.pubescens (Kroyer), just 



as E. prideauxi is always found associated with the Cloaklet 



Anemone {Adamsia palliata) . 



Out of several thousand Common Hermit-Crabs which I 

 have taken at one time or another there have been three asso- 

 ciated with the above Sponge. In June last year I took a very 

 small Adamsia, about 3 mm. wide, of course with an immature 

 E. prideauxi inside. They are locally called " Strawberry 

 Crabs." Fish do not seem to touch them for food, probably on 

 account of the stinging powers of the Adamsia. The Common 

 Hermit is, of course, a favourite item in the food of the Cod, 

 Thornback, and other fishes. 



Moulting and Regeneration of Galathea strigosa, Fabr. 



In February, 1908, I took two adult specimens of this beauti- 

 fully blue-banded Squat Lobster at low tide. One is fairly certain 

 to find them during spring ebbs either on the " Eilans " in Mill- 

 port Bay or about the Pier. 



I first noticed the larger one (a) to be carrying spawn (" in 

 berry" or ''with coral") on May 5th; hatching began on the 

 16th, and of course lasted several days. On July 21st, 1908, she 

 moulted, again in January, 1909, and again on the following 

 July 21st. A few weeks later this specimen died. 



The smaller one (b) spawned soon after a, moulted on Jul} 7 

 31st, 1908, again January, 1909, again on July 12th, and lastly 

 in December, but died a few days later. 



In April, 1909, considerably after the second moult in cap- 

 tivity, a cast off her right cheliped when I was holding her in my
