MOLLUSCAN NOTES. 



]iy Hugh C. Fulton. 



Read 8th January, 1915. 



No. 1. — Stenopylis, Fulton, Ann. Mag. Nat. Hist., vol. xiv, 

 p. 163, 1914. 

 Tn my short paper quoted above, I omitted to note that Mr. Charles 

 Hedley gave an account of the radula and jaw of S. hemiclausa, Tate, 

 in the Appendix to Professor Tate's paper (Horn. Exped., Mollusca, 

 1896, p. 221). Professor Bavay informs me that his S. microdiscus 

 has only Zh whorls, not 4^ as depicted by the artist. As I can see 

 no difference between this species and the previously described 

 S. hemiclausa it falls into synonymy. 



No. 2. — Ennka affectata, Fulton, and E. rosenbergiana, Preston. 



Having had tlie opportunity of examining a co-type of £J. rosen- 

 lergiana^ Preston (Proc. Malac. Soc, vol. ix, p. 53, fig., 1910), 

 I find it is identical with the shell described by me as JE. affectata in 

 vol. V, p. 32, 1902, of the same Proceedings. My specimens were 

 obtained through Mr. Rosenberg, and formed part of the collection of 

 the late Mr. A. Boucard, and were labelled " Zanzibar". Mr. Preston's 

 specimens are said to have been collected in Angola, W. Africa, by 

 Dr. Ansorge. 



No. 3. — ToMiGERUs L^vis, Ihering. 



I received from Mr. Dias da Eocha, collector of the type-specimens, 

 some original specimens of Tomigertis Icevis, Ihering (Proc. Malac. 

 Soc, vol. vi, p. 197, 1905). I have no hesitation in pronouncing 

 them to be simply dead and weathered examples of I'omigerus clausus, 

 Spix (Testae, lirasil, 1827, pi. xv, figs. 4, 5). Although the corrugation 

 on the last half-wliorl is, owing to the worn condition, weaker than in 

 T. clausus, it is clearly present in every one of tlie twelve specimens 

 examined by me. Tlie only difference between these two forms noted 

 by von Ihering is tliat lavis is smooth and ivliite. To me tlie loss 

 of colour and smoothness has evidently been caused by weathering, 

 and the type must have been a very worn .specimen if it showed no 

 signs of the corrugations characteristic of T. clausus. 



No. 4. — Cladsilia falcifokmis, var. Montana, Mcilldff. 

 In the Nachr. deutsch. Malak. Gesell., 1901, p. 77, Dr. von 

 MollendorfF described a Tonkin Clausilia under the above names. 

 As no previous species has been described as falciformis I propose 

 that the varietal name be dropped, and tlie species be known as 

 CI. falciformis, Molldff. It is evident that Mollendorff intended to 

 write fdlcifera, Bav. & Dtz. (Jonrn. de Conch., vol. xlvii, p. 290, 

 pi. xii, fig. 10), a species to \\\\\g\\ falciformis is allied, but is, in my 

 opinion, quite distinct ; they are similar in form, but falciformis 

 is much larger, of a darker coloration, and has a much coarser
