154 Rev. T. Hincks's Catalogue of Zoophytes 



ing species of Actinozoa, such as Peachia hastata. The dredging 

 is equally productive. The rough ground (at from 15-20 fa- 

 thoms) yields in rich profusion the various stony Polyzoa {Lepra- 

 lia, Membranipora, Cellepora, &c), while under the rocky shores 

 the Vesiculariadse abound ; and in certain spots the Halidrys is 

 taken up, festooned with the beautiful Mimosella gracilis, which 

 has hitherto been found only on the western coast. 



The Salcombe 'estuary, between Torbay and Plymouth (the 

 favourite dredging-ground of Montagu), is also full of attrac- 

 tions for the zoophytologist. It is peculiarly rich in the Lami- 

 narian species, — a fine belt of weed edging its rocky shores, and 

 including several large Zostera-heds. At the low spring-tides, 

 it is also unsurpassed for shore-collecting. The finer Actinias 

 occur in great plenty and splendour. A little way up the estuary 

 there is a Scallop-bed, on which Membraniporidse and some of 

 the Cyclostomata abound. Plymouth Sound and Start Bay are 

 likewise prolific hunting-grounds, while the rocky and precipi- 

 tous shore in the neighbourhood of Dartmouth yields a rich 

 harvest of Actinia?. 



Through the Brixham and Plymouth trawlers, acquaintance is 

 readily made with the products of the Coralline zone. Their 

 labours are chiefly carried on in about 30 fathoms 5 depth ; and 

 here the larger Sertularian zoophytes are taken up in immense 

 quantity and of most luxuriant growth. The most characteristic 

 species are Sertularia argentea and abietina, Plumularia falcata, 

 Laomedea longissima, Campanularia verticillata, and Coppinia 

 arcta. Sertularia tamarisca and Antennularia antennina are 

 also abundant. Plumularia myriophyllum is of rarer occurrence, 

 and so are S. nigra and pinnata. Eschara foliacea is brought up 

 by the trawlers in great quantity at certain points, and Gorgonia 

 verrucosa is common all along the coast at a depth of from 30-40 

 fathoms. The very rare Caberea Boryi belongs to this region, 

 being frequently parasitic on the Eschara. 



The materials which I have been able to obtain from still 

 greater depths are but scanty. They consist almost entirely of 

 Pinnae, taken up in a range off the Deadman Point, from about 

 60 fathoms. They are thickly crusted with various species of 

 Lepralia {reticulata, trispinosa, linearis, variolosa, Malusii, &c), 

 with Alecto and Hippothoa, Diastopora, and Tubulipora {patina, 

 hispida, and serpens), and bear considerable numbers of the 

 Tubulipora penicillata. Plumularia Catherina is also found upon 

 them. I shall give a complete list of the species procured from 

 this locality in another portion of this paper. 



The wealth of the district now under consideration will be 

 best appreciated if we compare the number of species included 

 in this list with that contained in the largest local catalogue
