Neritina mertoniana Reel.— Many specimens. This is pro- 

 bably, as considered by Tryon, a variety of 7\^. uahinensis Less., which 

 closely mimics the common West Indian N. virginea, L., and is equally 

 variable in its markings. Indian Ocean to Philiiipines and Polynesia. 



Family TURBINID^. 



Phasianella (Orthomesus) variegata Lm.— We give the above 

 name to two examples of a small, smooth, closely interruptedly white- 

 lined Phasianella, with some little doubt, the exact variety not being 

 found in the Mus. Brit., but it seems near P. fiiTOsa, P. leutiginosa^ 

 and other quasi species now aggregated by Pilsbry under the above 

 name.- 



Turbo (Senectus) radiatus Gm.— Many, in all stages. Red 

 Sea to Madagascar, eastward to New Caledonia, Nicobar, Philippine, 

 and Loyalty Islands. 



Family TROCHID.E. 



Polydonta maculata L. van — Several specimens of this protean 

 species, differing from the type in some respects. Philippines, Singa- 

 pore, Fiji Islands, Indian Ocean, Kingsmill Island. 



Polydonta veneta Rv. — .\ few examples of a species allied to P. 

 radiata (im. but without teeth on the columella. Moluccas (Rv.). 



Polydonta (Carinidea) radiata Gm.*— Many, in all stages ot 

 growth. Red Sea, Indian Ocean, Singapore, Madagascar, Ceylon. 



Umbonium vestiarium L.* — A large number of specimens, 

 apparently not so variable or light in colour as examples from the 

 Western shores of India. The var. rosea, however, is present, and 

 the variety with slaty black umbilical callosity. Indian Ocean, 

 Ceylon to Java, Philippines, Singapore, New Irealand. 



Gibbula nuclea Phil— Typical specimens. New Caledonian 

 Archipelago, Jaj)an, Fiji Islands (Garrett). 



Minolia biangulosa A. Ad. — An abundant South Indian 

 Minolia, the whorls being excessively angulate. We have lately seen 

 dredged from Ceylonese waters by Capt. Tindall, of the s.s. " Patrick 

 Stewart," over a hundred, showing no variation whatever. Siam. 



Minolia variabilis A. Ad. — Also extremely abundant, and, as its 

 name would imply, variable. Persian Gulf 



Calliostoma interruptum Wd. — We have identified this by 

 Reeve's llgure and description, not having seen any named individuals. 

 It is an elegant little trochiform shell, i)retlily longitudinally banded, 

 and articulately fiUetted at the periphery. Habitat hitherto unknown.
