to the collection this year. The specimens (many of them 

 representing species new to the collection) were collected and 

 presented by the late Dr. W. T. Blandford, F.R.S. 



A beautiful example of the very rare Voluta thatcheri, and a 

 very fine specimen of Fusus pagoda, one of the most remarkable 

 of the many curious forms of Mollusca from Japan, were also 

 obtained at this time, the former by purchase and the latter by 

 donation from J. Lewis, Esq. 



1883. 



This year was purchased a series of 1180 land and fresh- 

 water shells from the collection of Mr. J. B. Gassies. Many of 

 the specimens are the actual types described and figured in his 

 work, entitled " Faune Conchy liologique terrestre et fluvio- 

 lacustre de la Nouvelle Caledonie," or in the " Journal de Con- 

 chyliologie." 



A great addition was made at this time to the collection of 

 Clausilia by the purchase of 1579 specimens from all parts of the 

 world. The whole series was especially valuable as having been 

 examined and identified by Dr. O. Bottger, who made a special 

 study of the group. 



1884. 



The collection of land and fresh-water Mollusca, comprising 

 833 specimens, obtained by the " Challenger " Expedition, was this 

 year added to the collection. It included 150 different species 

 of which 21 were new to science, and were described by E. A. 

 Smith in the Proc. Zool. Soc, 1884, pp. 258-281. 



1885. 



One of the most important additions to the collection this 

 year consisted of 4687 specimens of shells dredged during the 

 expeditions of H.M. ships Lightning, Porcupine, Knight-errant 

 and Shearwater. It comprised a set selected and put aside for 

 the Museum by the late Dr. Gwyn Jeffreys, F.R.S. , who pub- 

 lished detailed accounts of the Mollusca obtained by those 

 expeditions. After his death they were handed over to the 

 Museum by his executors. The collection contained a large 

 number of types and illustrated the deep-sea Molluscan fauna of 

 the North Atlantic, which was hitherto entirely unrepresented 

 in the Museum collection.
