16 Melvill, Descriptions of Marine Mollusca 



A thick, almost smooth shell, but when examined with 

 a lens it is found to be uniformly spirally striate. Four- 

 whorled, the whorls tumid, and painted below the sutures 

 and in the middle of the last whorl with square brown 

 spots, the surface between being mottled with lighter 

 ochraceous-brown painting, as is also the case at the 

 base. This is likewise spirally striate. The umbilical 

 region is crenulate, the umbilicus itself narrow. Mouth 

 quite round; peristome not much thickened, simple. The 

 nearest ally is the more sombre-coloured M. rotnndata 

 Sowb., from Hong Kong (Proc. Mai. Soc, Vol. I., p. 158, 

 pi. xii., f. 19), with which it agrees in size, and the 

 character of the thickly crenulated basal ridge fringing 

 the umbilicus ; but we have compared it closely with the 

 types, and find many differences, notably in the striolation. 



MlNOLIA CLIMACOTA, Sp. 110V. (Pi. J, f. 22). 



M. testa gradato-conica, snbdepressa, anguste umbilicata, 

 solida, albo-ochracea vel albo-cinerea, anfractibns septem, apud 

 suturas multum impressis, undique irregulariter spiraliter arete 

 liratis, liris conspicnis, sulctdosis, pulchre tornatis, infra juxta 

 anfractiinm suturas nigris, nigro-rufis vel cinereis flammis 

 maculisve depictis triangidaribus, basi planata, l&vissima, ad 

 peripheriam unangidata, infraque peripheriam brunneis vel 

 cinereis flammis decorata, apertura angtdato -rotunda, labro 

 simplice. 



Alt. 14, diam. 14 mm., sp. maj. 



Hab. Charbar. 



Though allied to M. variabilis Sowb., we do not think 

 this shell a form of that species. Four specimens are 

 before us, the three larger of these being gradate, and 

 from them the above description is taken; the smaller 

 shell, perhaps not full grown, is, as in the types, very 

 deeply spirally lirated and sulculose, the triangular
