From a higher level in Christchurch parish, about 200 fecr, 

 Cifprcea spurca^ Bulla striata, and Tdlina decora were obtained for 

 ns by Mr. Brocklehiirst, jun. 



Mr. E. A. Smith favours us Tvith the following remarks on the 

 mollusca : — " From the collection 25 species have been determined, 

 and they are all species found in the West Indies at the present 

 time. The Barhatia and the unnamed species of TeUlna also agree 

 exactly with specimens from the AVest Indies, but the true specific 

 names are doubtful. Of many of the species there are sufficient 

 specimens to enable a careful comparison with the recent forms to 

 be made, and there is no such variation from these forms as might 

 be expected if the reefs were of considerable nge. These lower 

 reefs are clearly of very recent date, certainly Pleistocene, and pro- 

 bably late Pleistocene. The mollusca are such as might be found 

 in a raised beach." 



It is interesting to note that Mr. R. J. L. Guppy, F.G.S., in 186f) 

 had observed that the coral-rock of Barbados contained a large 

 number of recent species of mollusca, and that no extinct species 

 had been recorded from it*. 



Mr. J. W. Gregory, F.G.S., has examined the small collection of 

 corals which one of us brought back to England, and we have to 

 thank him for the amount of time and trouble which he has ex- 

 pended on the work. He reported that he found it difficult to 

 compare the broken fossil corals, many of which were only casts in 

 infiltrated calcite, with the perfect recent specimens in the British 

 Museum. To meet this difficulty a special collection of recent 

 corals from the Barbadian reefs was obtained and sent over by 

 Mr. G. F. Franks, M.A., F.G.S., to whom we are much indebted both 

 for this and for valuable aid in collecting fossils from the rocks 

 of Barbados. The corals are not yet fully worked out, but Mr. 

 Gregory has been able to identify the following species ; of the 

 localities mentioned Ceres is about 70 feet above the sea, Ellis Castle 

 about 500 feet. Groves is about 700 feet, and Castle Grant 1050 feet.
