from deep water off the Cornish coast measures more than 
14 inch in circumference, and is covered with about thirty of 
the little “papillary eminences” which are so characteristic of 
the species. The intercellular pores present the pretty stellate 
appearance which Mr, Busk has noticed in Heteropora clavata. 
[Isle of Man; Rothesay Bay, mouth of the Clyde; Shet- 
land, &c.] . 
Fam. Crisiade. 
1. Crista, Lamouroux, 
1. C. eburnea, Linneus. 
Common. ° 
2. C. denticulata, Lamarck. 
Very common: abundant in Saleombe Bay, &c. 
2. Cristp1a, Milne-Edwards. 
C. cornuta, Linneus. 
Common in Devon; Cornwall (Couch). 
The only Crisidia which I have met with is the form in which 
the spine springs from the side of the cell beneath the aperture. 
This is the C. setacea of Couch, but is probably only a variety of 
the C. cornuta. 
Suborder Ctenostomata, Busk. 
Fam. Alcyonidiade. 
_ 1. Atcyonrpium, Lamouroux. 
1. A. gelatinosum, Pallas. 
Salcombe Bay, Devon; Cornwall, “on shells and stones from 
deep water; not rare on the south and south-west coast” 
(Couch). 
2. A. hirsutum, Fleming. 
Common between tide-marks. This species attains a large 
size on the South-Devon coast, forming very beautiful palmate 
masses, variously lobed. 
In its crustaceous state, it is the Cycloum papillosum of 
Hassall. 
3. A. parasiticum, Fleming. 
Not éommon: Salcombe Bay; Cornwall. 
4, A. hexagonum, Hincks. 
Very common, on stones, weed, &c., between tide-marks, and 
also from moderate depths.
