New habitat for Qdostomia pallida. — The usual 

 habitat for Odostoinia pallida is, as is well known, on the ears of 

 Pecten opercularis or P. jnaximus ; but what I imagine to be an 

 entirely new habitat has just been brought to light, viz : on the 

 operculum of Turritella terebiu. These latter were taken in 

 large quantities in a small trawl in Sullom Voe, Mainland, Shet- 

 land, depth about 10 fathoms. An Odostomia was observed on 

 the operculum of one which led to a careful investigation. After 

 lying a short while undisturbed in a sieve, many of the animals 

 protruded themselves, immediately withdrawing however on the 

 slightest touch ; by careful looking over, about a dozen specimens 

 were secured, each having an Odostomia, and in one case two, 

 attached to the operculum. These were all of one size, about 

 half grown ; a few were placed in salt water, but the partnership 

 ceased when the water became insufficient, and the Odostomice 

 dropped off. The specimens of Turritella that were allowed to 

 dry, had to be broken to procure the Odosiotnia, which was 

 withdrawn with the operculum. A number of specimens of P. 

 operadaris were obtained in the same haul, some few with adult 

 Odostomia pallida on the ears. — R. W J. Smart, Oct., 1886. 



BIBLIOGRAPHY. 



Museum Normanianum, or a Catalogue of the In- 

 vertebrata of Europe, and the Arctic and North Atlantic Oceans, 

 which are contained in the collection of the Rev. Canon A. M. 

 Norman, M.A, D.C.L., F.L.S. 



This catalogue, of which three parts are already issued, 

 containing the Echinodermata, Pantopoda, and Crustacea, is a 

 list of the species inhabiting the area north of north latitude 35° 

 in the magnificient collection formed by Dr. Norman, at Burn- 

 moor Rectory, Fencehouses, Co. Durham. The Echinoder- 

 mata, of which 194 species are listed, is mostly deficient in 

 North-East American forms, especially the Holothuroidea, 

 in the deep sea Atlantic species, and in Mediterranean and 

 recently described Arctic species.
