361 Kev. T. Hincks^s Catalogue uf Zuophytes 



Fauna ' is identical with this species. He obtained it at Naples, 

 in from 10-20 fathoms' depth. 



2. Z. sulcatus, Gosse. 



Mr. Gosse mentions a single colony of this pretty but very 

 minute species as having occurred to him at Broadsands, near 

 Brixham, on sandstone rock. On the opposite side of Torbay, 

 however, and very close to Torquay, I have found it abundantly 

 in the small basins hollowed out in the limestone, which I have 

 before referred to as yielding the Clavatella prolifera. 



The Zoanthus forms little colonies on the floor of these minia- 

 ture pools ; but they may readily be passed over as tufts of some 

 minute weed. 



3. Z. rubricornis, Holdsworth, Proc. Zool. Soc. March 12, 1861. 



This species has lately been described by Mr. Holdsworth, 

 who obtained it in Plymouth Sound, at a depth of 20 fathoms. 



Fam. Caryophylliadae. 



1. Caryophyllia, Lamarck. 



C. Smithii, Stokes. 



Common, near extreme low-water mark : Torbay, Salcombe, 

 Dartmouth, Polperro, &c. Dredged off Berry Head. 



2. Sphenotrochus, Milne-Edwards. 



S. Macandrewanus, M. -Edwards. 



I insert this species in the catalogue on the strength of a 

 very minute specimen which I found amongst some shell- sand 

 brought in by trawlers to Plymouth. I have had very fine ex- 

 amples from Mr. Barlee, which were dredged off some part of 

 the Cornish coast, but beyond the limits of my present district. 

 Mr. Macandrew has also taken it in the same region, on clean 

 sandy ground. 



3. HoPLANGiA, Gosse. 

 H. durotrix, Gosse. 



Mr. Laughrin has supplied me with a specimen of this inter- 

 esting Coral from the coast of Cornwall. It had only been found 

 previously in Weymouth Bay. In this specimen a single small 

 and imperfectly developed Coral lite buds from the spreading 

 base of a full-grown individual. In the case of another Corallite 

 on the same piece of rock, there is no appearance of any basal 

 expansion.
