Miss Jorgensen adds a note of importance to her account of 

 the development of the common calcareous sponge Grantia com- 

 pressa. The larva appears to be free for at least 24 hours, and 

 is thus liable, like the larvae of so many other marine forms, to 

 denatation. She also gives an account of the larval stages of 

 the common shore crab ; and her drawings of the larvae of this 

 and other species will be found in the paper on Crustacea referred 

 to above. 



Interesting records of the Euphausian, Nematoscelis mega- 

 lops and of the parasitic copepod Caligus curtus with its parasites 

 are given under Faunistic Notes.
