might be the fate of Uigite, I do not dogmatically thrust it into the world 

 as a new mineral, but waiting for more information, would merely make 

 a note that such a compound as I have described is to be found at Uig, in 

 Skye.

Charles W. Peach, Esq., Wick. 



In March last year, I obtained from a fisherman's line an old and much 

 corroded valve of Psammobia ferroensis, which had been hooked up from 

 deep water ; on it T noticed jelly-like spots, and placed it in a shallow glass 

 of sea water ; the next day I fancied that I could make out, with my pocket 

 lens, zoophyte-like animals. At once I transferred the shell in a watch 

 glass, filled with sea water, to my microscope, and was delighted to find my 

 suspicion correct, for after a little management, so as to catch the light, I 

 could see the forms as figured (Fig. 1) attached to the shell by a short

foot-stalk, a little inflated near the upper part, tipped with a slightly 

 raised and rounded centre, from which extended four long and four short 

 leaf- like arms, each granulated down the centre ; one or two had, in ad- 

 dition, springing from these, delicate tentacle-like arms, probably in a 

 farther stage of development. They were easily disturbed, but soon again 

 displayed themselves ; their transparency, added to this shyness, rendered 

 it difficult to catch their forms. At first I thought they were the early 

 stage of a Hydractina, and probably, H. brevicornis of Miiller, men- 

 tioned in Johnston's second edition of " The British Zoophytes," page 35.
