 Oysters. Proc. Zool. Soc. Lond., 1901, pp. 372 — 394, 4 figs. 



Blanford, W. T. — Note on Bmsouia and on an apparently undescribed .species, 

 i». miincla. I'roc. Malac. Soc. Lend., 1901, voL iv, pp. 17S, 179. figs. 



The author gives a Hst of the known species of Br.nsouid, with their localities ; 

 and describes B. mimcla, n. sp. , from Narkander, E. N. E. of Simla, the type of 

 which has been presented to the British Museum. 



Blanford, W. T. — Note on Bensonia maimvaritif/i and MacrocJdamys daluigeiihls. 

 Ibid,, pp. I So — 182, figs. 



Dr. Blanford concludes that these two species are closely allied, or sub-specific 

 races of the same species, which would in that case bear the name M. mainwaringi, 

 Nev. The animal has not yet been seen, and so it is thought best to keep the two 

 distinct. A description of the shell of J/, mainwarinrjl is given together with the 

 synonymy.

The terrestrial Pulmonata of the Indo-AIalay region are from various points of 

 view of exceptional interest, but unfortunately widely differing opinions exist as to 

 their classification and affinities. This is no doubt largely due to our present inexact 

 knowledge of Iheir internal structure, and also in part to their having been classed 

 in genera, sub-genera, and sections upon the form of the shell, jaw and lingual 

 ribbon. 



The four genera treated of by Dr. Blanford are by some writers supposed to be 

 members of the Zunitichic, while others regard them as belonging to the Hclkidac or 

 LiDUtcidae. 



Dr. Blanford accepts Col. Godwin- Austen's view that in certain areas of the Indo- 

 Malay region, certain molluscs, "having shells so diverse that they were formerly 

 classed in distinct genera, or even in some cases different families or sub-families, 

 agree amongst themselves in each area, and differ from those in other areas by 

 characteristic details in the anatomy." 



The history of the names Xestlna and Xlhjiria is then explained, and the author 

 arrives at the conclusion "that Xeslitm and Nllgiria are identical. . . . The 

 group to whicli these names have been applied is neither a genus or sub-genus, but 

 merely a section of Ariophanta. distinguished by a character which is not of generic 

 importance." Then follows a list of 26 species referred to AriopJiantK, followed by 

 a similar one of Enplcda containing 31 species. The following are new : ^/. 

 canarica, A. hefcraea, A. gassii, E. trans fretata, E. agastyae, E. malaharica, 

 E. Jacvis, E. fluduosa, E. granulifrra, E.(?) mucronifera, and oribatcs. 



This re-classification is undoubtedly a step in the right direction ; far too many 

 genera and sub-genera have been made from closely allied forms of Indian molluscs, 

 and we regret to say this process of making a new sub-genus for every supposed 

 difference from the normal, still flourishes.

 I'ctat independant du Congo. Ann. Soc. Roy. IMalac. Belgique, 1901, T. 

 xxxvi, pp. 3—7, pi. i. 



The new forms are Achatina martdl and var. jhdlesccns, Melania lichrcclitsi and 

 Uiiio hriarli. Ch'iqmtra johnstoni, E. A. Sm., is also recorded and figured.

 Land and Fresh-water Mollusca. Ibid., pp. 385 — 408, pis. xix — xxi. 



The flow of new species of Japanese molluscs continues unabated. In the first 

 paper Dr. Pilsbry describes the following : I'roclioinorpha gouldiana, Macroddaviys 

 jKr/ragilis, M. giidei, Kalidla hoi-calis, Eulvta (Euhadra) oshi)nac, Odoritis
