MELVILL & STKES : MARINE SHELLS FKOM THE ANDAMANS. 227 



41. CoNus (Heemes) scABRnjscuLirs, Chemn. Allied to G.glans, Swn. 

 Reported from New Caledonia, and widely distributed throughout 

 Polynesia. 



42. CYPRiEA (Lttpoktia) heltola, L. Showing no variety. One of 

 the most abundant Eastern cowries. 



43. CEEiTHiirM ( Vertagus) obeliscus, Brug. A beautiful form, straw- 

 coloured, mottled with vivid grey at the sutures. Ranges throughout 

 the Eastern tropics. 



44. Ceeithitjm eobusttjii, Shy. According to Tryon (Man. Conch., 

 ser. I, vol. ix, p. 135), this is a variety of C. Traillii, Sby., which we 

 have already recorded from these islands. 



45. Teifoeis rubee, Hinds. One specimen, very richly coloured. 

 Reported from Bourbon I. and Mauritius, to Tahiti and the New 

 Hebrides. 



46. Scalaria latifasciata, Sby. A closely lamellate form, with 

 broad spiral brown banding. Allied, perhaps too closely, to 

 8. Clementina, Grateloup, of which S. trifasciata, De Haan, may 

 be only a variety. It ranges from Mauritius to the Philippines. 



47. Onfstus Indicus, Reeve. Ranges throughout the Indian Ocean. 



48. * Xenophora solarioides, Reeve. A small and very distinct 

 species, whose headquarters are the Philippine Isles. 



49. Mitrctlaria equestris, L., var. dormitoria, Reeve. One of the 

 most variable of shells, and also one of the most widely distributed, 

 occurring in both hemispheres in one or other of its forms. 



50. MiTRULARiA TECTUM- siNENSE, Lam. A. coucentrically laminated, 

 conical species, perhaps not specifically separate from the foregoing, 

 bat less widely distributed, not having been recorded as yet from 

 American shores. 



51. Yanikoro Deshayesiana, Recluz. It may not be out of place 

 here to state that Vanikoro (1832) of Quoy & Gaimard has precedence 

 by nine years over the more familiar Narica, Recluz. The former 

 name has been objected to as being barbarous, having been so 

 christened after the Island of Yanikoro, where the original species 

 {V. cancellata, Lam.) was discovered. Barbarous terms are not 

 altogether forbidden, only discountenanced as much as possible by 

 the rules of nomenclature, and for our own part we much prefer such 

 a name to one which might be confusing, Narica and Natica only 

 differing by a single letter. Anyhow, Leucotis, Nwainson, 1840, has 

 precedence by one year over Narica, while Merria, Gray, was not 

 established until 1842. 



52. Turbo radiatus, Gmel. Yery fine specimens. Operculum 

 shining, with a greenish tinge. Under this name Mr. Pilsbry (Man. 

 Conch., ser. i, vol. x, p. 200) unites many of Kiener and Reeve's 

 Avell-known species. The distribution is most extensive, ranging over 

 the whole Indo -Pacific province.
