flagellata, Chajtognatha, a Polyclad, Polychseta, Crustacea, 

 Heteropoda, Ptei'opoda and Urochorda. Nearer the coast the 

 Radiolaria, particularly the colonial forms, were less abundant. 



The mass of deposit brought up by the bucket-dredge consisted 

 almost entirely of calcareous organic structures. The great bulk 

 of this was composed of calcareous Polyzoa, mostly in small frag- 

 ments, with numerous Foraminifera, many shells, and a consider- 

 able number of small solitary corals. The representatives of the 

 last-named group which have been examined by Mr. J. S. Den- 

 iiant, M.A., F.R.G.S., comprise Platyotrochus compressns, Ten. 

 Woods, Deltocyathns rokeformis, Ten. Woods, Dimocyathus 

 parasiticus, Ten. Woods, Leptopaiuus discus, Moseley ?, Koto- 

 phyllia recta, Dennant, Holcotrochus crenulatus, Dennant, Flahel- 

 lum australfi, Moseley, Trematotrochus verconis, Dennant ?, and 

 two new species, one of Trematotrochus and the other of Flahel- 

 lum. A few small sponges, not yet determined, were attached to 

 the tangles. The Polyzoa are being examined by Mr. C. M. 

 Maplestone.
