M. chalmersi n.sp. (pi. 4, figs. 3 and 4). 



Shell elongate, fusiform, smooth, shining, white with a very beauti- 

 ful series of olive-green (or pale reddish) and black markings on the 

 last whorl arranged as follows : — Immediately below the suture rather 

 br.oad gre(mi5'.h streaks are set somewhat obliquely ; then comes a 

 band of upright longitudinal black strokes close together, the strokes 

 being sometimes joined two or three together either above or below ; 

 then a band of oriental characters, further apart and somewhat vari- 

 able both in colour and form ; then a solid band of yellowish-green ; 

 then a band of black longitudinal strokes (the strokes being rather 

 more oblique than in the second band) which sometimes unite to 

 form characters ; below this is another solid band of yellowish-green, 

 often interrupted ; then a band of upright black strokes, sometimes 

 united as before ; and finally five or six longitudinal green markings 

 on the area at the lower end of the canal. Protoconch blunt, tipped 

 with brown ; whorls 4^, flattened ; suture but slightly marked ; aper- 

 ture elongate, narrow ; outer lip thickened, denticulate within, with 

 about six olive-green linear markings outside ; columella four-plaited. 



Long., 5 mm.; diam. max., 275 mm. 



Hab. : S. Thome Island. 



In the few specimens so far received the system of banding is 

 remarkably constant. One or two examples show traces of a line of 

 greenish colour on the last whorl below the suture. The pale 

 reddish-tint (instead of olive-green) is, we think, simply the effect of 

 weathering. In form, this shell resembles M. fusifonnis Hinds. 

 AI. bavayi Dautz., also from \\^est Africa, is much larger and differently 

 marked. This species is named after Mr. J. Chalmers, of the West 

 African Telegraph Company's service, who discovered both these 

 species in S. Thome. The types are in the Brit. Mus. Nat. Hist., and 

 specimens are also in the Manchester Museum. 



Land Shells from Largs. — I recently sent the Recorder a small box of shells 

 collected at Largs by the late Rev. R. Boog Watson. The species are as follows: — 

 Hyalinia liicida Drap. , JI. nitidtila Diap. , H. ciystallina Miill., H. cellaria 

 Miill., H. alliaria Miller, H. pnra var. nitidosa Gray, Avion hortensis Fer., 

 Pyra/iiidiila rotundata Miill. sub- var. ohscnrata D. & M,, Vitrina pelhtcida Miill., 

 Helix nemoralis L., Pupa cylindracea DaC, Claiisilia bidentata Strom, and 

 Cochlicopa lubrica Miill. Of these Hyalinia Iiicida is a new county record for
