only question is, shoxikl these subgenera (or genera) not be united, 

 when such links are found to exist between them ?] 



33. Latirus (Peristeknia) pulchella, Reeve. One specimen, hardly 

 full-grown. 



34. Latirtjs (Peristernia) Marqtjesa, A. Ad. Quite characteristic. 



35. Phos rufocincta, Smith. Not in very good condition. 



36. *Phos texxum, Gmel. Probably this species, but not full- 

 grown. 



37. *J^ASSA (Arcularia) globosa, Quoy. Of the variety known 

 as clathrata, Kiener. 



38. ^Nassa (Alectrion) bifaria, Baird. Considered by some a 

 variety of N. hirta, Kien. 



39. ^Nassa (Alectrion) elegans, Kien. Apparently distinct from 

 iV^. glans, L. 



40. *Nassa (Alectrion) moxilis, Kien. A well-known species. 



41. *Nassa (Zeuxis) Marratii, Smith. A remarkably pretty and 

 distinct species ; variably coloured, and more or less smooth. 



42. ^'Nassa (Niotha) albescens, Danker. Common and typical. 

 Known by its darker apex and white body-whorls. 



43. Nassa (Niotha) eucojiista,' n.sp. PI. XIII, Fig. 11. 



N. testa ovato-fusiformi, concinna, pallide brunneo-ochracea, an- 

 fractibus 7, duobus apicalibus, pellucidis, caeteris uudique decussatis, 

 gemmulatis, apud suturas compressis, apertura ovato-oblonga, labro 

 niveo, nitido, intus denticulato, margine columellari infra parietem 

 uniplicato, duabusque plicis apud basim instructo. Long. 18, 

 lat. 8-50 mm. 



An extremely neat species, allied to N. cremata, Hinds, and iV^. stig- 

 maria, A. Ad. The whorls are seven, two being apical and glassy, 

 the remainder are small, with the exception of the last, which 

 increases rapidly, the sutures are channelled, and the decussation over 

 the whorls is extremely regular, close, and precise, presenting a turned 

 or chased appearance of great beauty. The mouth is ovate oblong, lip 

 white, shining, hardly callous, denticled within, and at the columellar 

 margin once-plaited just below the suture, and also slightly two-plaitecl 

 at the base. 



44. Nassa (Niotha) margaritifera, Dunker. We have what is 

 probably a variety of this species. 



45. ^Xassa (Niotha) stigmaria, A. Ad. A characteristic and very 

 attractive Andaman species, which varies a good deal. 



46. ^Nassa (Hebra) sistroidea, Nevill. Perhaps a variety of 

 iV. suhspinosa, Lam. Our two specimens are not mature. Mr. E. A.
