III. ^otes and Descriptions of new Species. 

 Genus Macbochxamts. 



1. MaCEOCHLAMTS ? STEPHUS, Bs. (p. 441). 



This species has a small left shell-lobe, shaped as in Cycloplax 

 (see fig. 4, pi. xxxi., Land and Freshwater Moll. Ind.). Jaw with 

 prominent central projection. 



It therefore does not, so far as the mantle is concerned, agree 

 with typical Macrochlamys. Better spirit-specimens are required 

 for examination. 



4. Maceochlamts choinix, var. gigantea (p. 441). 



In a MS. copy of JVevill's ' Hand-list ' M. gicfantea is catalogued 

 as a variety of choinLv — " ? a distinct species. Collected by 

 F. A. de Eoepstorfe, Esq. Diam. 19-25; alt. 10-25 mm." I 

 h.ive not seen an example of this species. 



6. Maceochlamts woodjiasoniana, Nevill MS. (p. 441). 



This species is no. 33 of XeviU's - Hand-list' (p. 23). The type 

 is in the Indian Museum, Calcutta, obtained by Mr. J. Wood- 

 Mason. 



7. IVIaceochlamxs honesta, var. texuioe (p. 441). 



This species is recorded in Nevill's ' Hand-list ' (p. 24) as the 

 Moulmein variety ; and this is the typical locality, and collected 

 there by Stohczka and Theobald. It is also recorded from Preparis 

 Island, the most northerly of the Andaman Group, from the 

 collection of Ferd. Stoliczka. I have in my own collection three 

 specimens given me by Stoliczka, undoubtedly a variety of lionesta, 

 but the locality marked on the label is " Nicobar ? " ; so I refrain 

 from describing it at present. 



8. MACEOCHlAilTS rOEDIAXA, G.-A. (p. 44l). 



This species is no. 39 of Nevill's 'Hand-list'; it was unnamed 

 when the catalogue was published. In his MS. catalogue Xevill 

 has entered it as fordiava in ink, and microsculpta in pencil. Four 

 specimens collected by Colonel Ford are the types in the Indian 

 Museum ; six specimens are recorded from Mr. de Boepstorff. I 

 adopted the title fordiana, though I find microsculpta on labels in 

 de BoepstorfE's shells that have come to me. This species was 

 described by me in the ' Annals and Magazine of Natural History ' 

 (ser. 6, ii. p. 57, 1888). 



9. Maceochlamts aulopsis (p. 441). 



Nanina aulopsis, Bs. 



Thalassia in !Xomencl. 



Thisis a true MacrocMamys. The right sbell-Iobe iswell developed, 

 the left was not well made out. The odontophore is similar to that 

 of the above genus, the formula being 20 — 8 — 1 — 8 — 20 about.
