NEW BRITISH ESCHARA. . 117 



the branches are raised, and although not so surrounded, are 

 pitted. 



Apertures, moderately large, rounded above and straight below 

 in the old, in the young occasionally bent downwards in the centre 

 in a V-like manner. The distal lips of the apertures — especially of 

 the young cells — have five openings on them ; the two lowest are 

 the largest, and stand upon little eminences, all very much resem- 

 bling the broken-off spines on many species of Lepralia. 



On one side of each cell — sometimes on one side, sometimes 

 on the other — is an avicularium on a conical elevation in the 

 young ; this is perforated on the top by a triangular opening, out 

 of which rises a golden bayonet-shaped vibraculum, which is 

 occasionally preserved on the old cells ; less so on the ver^j young 

 ones. This vibraculum occurs on some Lepralias. I never saw it 

 before on a British branched coral. This, with the roughened 

 border round the cells, and the spine-like openings on the distal 

 lip, justifies me in making it a new species. 



Although I have called it an Eschara (Escliara verrucosa) it 



may be a Cellepora, or even a new genus. This must be left to 



some authority to decide. Unfortunately the specimen, though 



perfectly fresh when I got it, was broken from its attachment, 



therefore I can only give the height of the fragment, which is a 



little more than three-quarters of an inch, the stem and branches 



about one-tenth of an inch in thickness. I have given it the 



trivial name, from its rough warty appearance.

Sphenotrochus Wrightii, of Gosse. In the same box I turned 

 out a nice specimen of this pretty coral. It was got about the 

 same time as the Eschara. I am indebted to Mr. Waller for the 

 name ; he was with Mr. Hyndman when the specimens figured by 

 Gosse were dredged. Mr. Waller was on his way to his home in 

 Ireland, from dredging with Mr. J. Gwyn Jefireys, in Shetland, and 

 instantly recognised it when I showed it to him. 



As Mr. Mc, Andrew dredged Sphenotrochus Macanclreioanus, on 

 the Cornish coast, both the species described in the "British Sea 

 Anemones " have now been found on your coast.
