mastia )n(tmmill(iris, P. rohusta, Tethya hjncurlum (budding), 

 and magnificent examples of the massive form of CUona 

 celata, the largest specimen, from near Khoscolyn Beacon, 

 measuring 81 cm. by 20 cm. horizontally, and 12 cm. 

 vertically, and being probably not exceeded in size by any 

 sponge ever collected on the British coasts. 



Miss L. K. Thornely, who has carefully examined all 

 the material we brought back from this expedition, in- 

 forms me that we obtained 26 species of Hydroid 

 Zoophytes, including Halecium tenellum, Diphasia atten- 

 nata, Plnmularia echinulata, Eudendrium cap'dlarc, and 

 Garvela nutans. Miss Thornely has also given me a list of 

 the Polyzoa which she has identified from this cruise, 

 comprising 88 species, six of which have not previously 

 been recorded from that region (Anglesea) of our district, 

 viz., Scrupocellaria scrupea, Menihranipord pilosa form 

 dentata, Smiftia reticalata, Cellepora avicularis, Boiverhankia 

 caudata, Q,nd Pedlcell'ina cernuafoTui glabra. In a collection 

 made by Mr. F. Archer at Bull Bay, on the north coast 

 of Anglesea, later in the summer. Miss Thornely finds 25 

 species, including several of the rarer ones mentioned 

 above, and Cellepora ramidosa. 



Mr. Hornell tells me that this cruise gave for the first 

 time to our local fauna the Annelids Sp'mther oniscoides, 

 Nicomache lumbrkalis, Sahellaria spimdosa, large numbers 

 of Pol(/noe scolopendrina, and one example of Nychia cirrosa, 

 which, curiously, was first described as British by the 

 Swedish naturalist, Malmgren, from a wrongly named 

 specimen of Polynoe in the British Museum, labelled as 

 hailing from Beaumaris. 



On the third night we again anchored in Forth Dafarch, 

 and after dark the electric lights were again used for a 

 couple of hours. This time the large arc lamp was taken 

 to the stern and suspended close to the surface of the
