Spanish Head (see fig. 4), to be visited in a boat from 

 the steamer. The exposed sides, parts of the roof, and as 

 far down as can be seen in the clear water are closely 

 covered with romided red Ascidians adhering together in 

 masses, black and white sponges, and tufts of Tiihularia, 

 forming altogether a most striking sight. The sponges 

 are mostly Facliymatisjna jolinstoni , and the Ascidians are 

 Alder's Polycarpa glomerata, a somewhat variable species, 

 solitary specimens of which have been sometimes referred 

 to Styela rustica (a species which probably does not occur 

 at all in British seas). When touched these ascidians emit 

 forcibly tiny jets of sea w^ater from the branchial and atrial 

 apertures, and this with their colour has gained for them 

 the local name of the "red-currant squirters of the Sugar- 

 loaf cave." 



Publications. 



No new volume of the " Fauna " of Liverpool Bay has 

 been issued during the past year, but several L.M.B.C. 

 papers have been published and copies printed off and 

 stored away to form part of Vol. IV., which will probably 

 be completed in a year or so. These papers are : — Mr. I. C. 

 Thompson's " Eevised Report on the Copepoda," a lengthy 

 paper illustrated by 21 plates, and giving an account and 

 a figure of every species found up to now in the district ; 

 Mr. F. W. Gamble's Report on the Turbellaria of the 

 L.M.B.C. district, illustrated by three plates ; Mr. W. I. 

 Beaumont's Note on Lucernarians found at Port Erin ; 

 and Mr. H. C. Chadwick's account of the haemal and 

 water-vascular systems of some of our star fishes, with 

 four plates. 



Amongst future papers which will probably be laid 

 before the Biological Society this session as an outcome of 

 work at Port Erin are ; — On Synapta by Mr. Chadwick,
