scope, and so I leave it still an open question. As for the embryo 

 of L. geniculata, I have seen it scores of times, and your wood-cut 

 No. 25, is identical with my sketch of it. The tentacula were 

 twenty-four in number." F. W. L. Thomas, R. N. 



Localities, <$rc. of some Zoophytes upon the North and East 

 Coasts of Britain. By Lieut. F. W. L. THOMAS, R.N. 



CLAVA MULTICOKNIS two fms. Kincardine, River of Forth, on Sabel- 

 laria, associated with T. Larynx, C. ciliata, &c. 



HYDRACTINIA ECHINATA on old shells, from Estuary of Thames to 

 Orkney Isds. The polypes are in a single whorl upon the mu- 

 ricated papilla, and arise from a little above the base. 



COKYNE PUSILLA a, small, grey, heads ovate. Orkney Isds. (about 

 | inch high.) /3. larger, polypidom wrinkled throughout (=C.ra- 

 mosa 1} Orkney Isds. y. deep sea ; heads pink, subcylindrical. 

 Yorkshire. The polypidom of this species closely resembles 

 the creeping variety of C. dumosa. 



EUDENDRIUM BAMEUM forty-five fms., muddy bottom, offTynemouth : 

 rej. F. of Forth, (rare to me). 



EUDENDRIUM RAMOSUM Coast of Suffolk, Northumberland, Aberdeen- 

 shire, River of Forth, Orkney Islands. This extensively dis- 

 tributed zoophyte has been found from a depth of forty fms. in 

 the open sea to the half-tide mark upon Alloa pier, River of 

 Forth, where the water is often sufficiently fresh to be drink- 

 able. The polypidom is constantly black, or of a dark-brown 

 colour. I believe that this and the rest of the Tubulariae 

 periodically lose their heads. At Alloa none were found with 

 " heads " on in the month of November. 



TUBULARIA INDIVISA Es. of Thames to Orkney Isds. Forty-five 

 fms. to litt. On the oozy bottom which lies outside of a line 

 drawn between Flamborough head and the Staples, this zoo- 

 phyte grows to a very large size, and is there associated with E. 

 rameum, Plumularia frutescens, Pennatula, Virgularia, &c. The 

 experiment was made of placing it in fresh water directly on 

 taking it from the sea, but no immediate effect followed. In 

 some a red mark half-way or one-third down the tube showed 

 the presence of the heir to the crown, though the incumbent 

 seemed in robust health. 



TUBULARIA LARYNX everywhere, in brackish water at Kincardine,
