NOTE. 



Note on Two varieties of Arion SUbfuseus, Drap. Mr. H. Overton has 

 recently submitted to me for identitication two examples of Ariou siibfiisciis, Drap., 

 collected b}' him in Sutton Park, Sutton Coldlield. 



The larger of the two specim^n.s, although not quite full grown is undoubtedly 

 referable to the variety fta}li'l! us, Cllge., described by mc in 1S03 (.\nn. and Mag. N". 

 H., 1893, s. 6. vol. xii, p. 252) as Ariou fia^ell 11 > 



The smaller specimen, when alive, e.xhibited two dark grey lateral bands, tlic 

 portion beneath being white as well as the foot-fringe and foot sole. The whole of 

 the dorsum was a light grey ; the mantle similar to the type.

 I — 10. Philadelphia : Academy of Natural Sciences. 



With the commencement of volume xvii the genus Achatiua, Lamarck, is dealt 

 with. After a few notes on the distribution, parasites and nomenclature, a key to the 

 West African species is given, and the systematic review commenced. 



The following new forms are described : A. aclinfiua, L. var uiouochroiuatica, 

 from .-Vngola, and .tI. occidcntalis, from Corisco Island, West Africa. A. pauflicni, 

 Fer. var. Iciicoslyla, Wasin Island, northern Zanzibar, var. clirysodcniia, from Mauritius, 

 and A. fiilica, Ker. var coloba.

new species. Proc. .Malac. Soc. Lond., 1904, vol. vi, pp. 138— 151, 7 figs, in text. 



One hundred and seventeen species are listed of which the following are new : 



Eulota i^lohosii, Liuiiiaca mars, L. (Giihiaria) icluvtoui, L. {G.) sJiantiiugeusis, L. (G.) 



petliti, Assimiuca uorbiiryi, and Pecten (Chlamys) farrcri.

Mr. Petch's paper forms an admirable resume of the work done in this particular 



distiict on the Land and Freshwater Mollusca, but it is greatly to be regretted that, 



at a time when malacologists are prepared to sink all petty differences as to special 



views on nomenclature, in order to obtain uniformity, that the old nomenclature has 



here been adhered to ; apart from this feature, the list is admirable and reflects great 



credit on its author.

 Mag. N. H., 1904 (s. 7), vol. xiv, pp. 159, 160, 2 figs. 

 Aniastra (Kauaia) rex. n. sp., somewhat recalls in form and appearance Hclicina 

 a^liitinans. It belongs to the group of A. alata, Pfr., and A. lidicifonuis, Ancey. 



Eliot, C N. E. — On the Doris plauata of Alder & Hancock. Proc. Malac. Soc. Lond., 

 1904, vol. vi, pp. 180, 181. 

 The author has examined specimens of Platydoris plauata from Plymouth, and 

 finds that they have all the essential characters of the genus Geiiodoris. Whether or 

 not the G. complauata, Bergh, is specifically distinct is doubtful, but if the same, the 

 name plauata (.A., and H.. 1855) has priority. Possibly the Platydoris plauata examined 

 by Garstang may be dislincl from those now described.
