NOTICES OF SERIALS. 131 



A Revision of the Arrangement of Bivalve Shells (Conchifera) ; (Gray, J. E., 

 Ph. D.) On Reproduction of lost part of an Operculum, and of its probable Re- 

 storation when entirely destroyed. Proceedings of Societies — Linnean — (Yates, J.) 

 On inflorescence of Cycas revoluta and Macrozamia spiralis ; (Clarke, J.) On the 

 parasitic habits of Bhinanthus Crista-galli ; (Newport, G.) On the Reproduction 

 of the lost parts in Earthworms. Three specimens of Earthworms were exhibited, 

 in which the lost parts of their bodies had been reproduced, as formerly proved by 

 the experiments of Bonnet and Spallazani, to take place in these animals. One of 

 the specimens was still living. These specimens possessed some interest from the 

 fact of reproduction in Earthworms, and other annelids having been recently denied. 

 In a report on the British annelida, by Dr. F. Williams (in the Report of the British 

 Association, &c, for 1851), after mentioning the statements made by Bonnet and 

 Spallazani, as quoted by Professor Owen, the following statement occurs: — " On the 

 authority of hundreds of observations, laboriously repeated at every season of the 

 year, the author of this report can declare, with deliberate firmness, that there is 

 not one word of truth in the above statement." " Dr. Williams," Mr. Newport 

 adds, " must have been unfortunate in his statements, since it is no uncommon 

 thing, at this season of the year, to find earthworms with a large proportion of the 

 body restored. (Hooker, Dr. J. D.) On Hodgsonia, a new and remarkable genus 

 of Cucurbitacece ; (Burton, G. B.) Notice of several species of Bats, captured in 

 England last autumn. The species referred to are Vespertilio serotinus, V. 

 Daubentonii, var. emarginatus, and the typical V. Daubentonii. Of V. serotinus, 

 three specimens were captured at Chartam, near Canterbury, in August last, 

 where it appears to be the common bat of the neighbourhood, although Mr. 

 Jenyns, to whom the specimens were submitted, states that he has seen but two 

 other English specimens. Their flight is graceful, but somewhat heavy ; and ap- 

 peared to be limited to about an hour after sunset. They seem to affect the neigh- 

 bourhood of high trees and shady places. V. Daubentonii, var. emarginatus, was 

 captured on the banks of the Stour ; and V. Daubentonii in the church-tower of 

 Christ Church, Hants. (Hogg, J.) Notice of the appearance of Myriads of a 

 species of Aphis, in the North of England, in the autumn of 1852 ; (Seeman, B.) 

 Remarks on Sarsaparillas. Miscellaneous — (Gray, Dr. J. E.) Occurrence of 

 Buncina Hancockii in pools, left between the rocks at low tide, in Belmont Cove, 

 Weymouth, but only on tufts of Hypnea purpuracens, which were infested with 

 Diatomacea, which induces Dr. Gray to believe that they feed on these parasitic 

 plants ; (Dareste, M. Camille) Note on Colouration of Waters of Chinese Sea. In 

 this note is recorded the occurrence in a sample of water from the Chinese Sea 

 (taken at a time when it was coloured to a great extent red and yellow) of 

 Trichodesmium erythrceum, which Ehrenberg described as the cause of the re- 

 colour assumed by the Red Sea at certain periods.
