following on tlie penultimate and last wliorls seem almost confluent, 

 producing the appearance of longitudinal riblets. The mouth is 

 narrow, oblong, outer lip somewhat thickened, sinus conspicuous, and 

 columellar margin straight. 



12. ^Pleceotoma (Drillia) vakiabilis, Smith. We have seen three 

 or four specimens, larger than those figured by Mr. Smith, and some- 

 what differently marked. 



13. *Pleukotoma (Dehlia) Wilmbri, Snjith. Two or three 

 specimens, fine, and typical of this very beautiful species, figured 

 in the paper already referred to (Proc. Zool. Soc. 1878). 



14. Pleukotoma (Surcula) bijubata, Reeve. Quite typical. 



15. Clathurella Hindsii, Reeve. A curiously sculptured species, 

 described (Proc. Zool. Soc. 1843, p. 186) as from the Philippine 

 Islands. It is nearly allied to G. carinulata, Souverbie, from New 

 Caledonia. 



16. Clathtjeella Reeveana, Dash. This, according to Tryon and 

 3Jr. Andi'cw Garrett, is the C. concinna, Dunker. One specimen only. 



17. Daphistella Boholensis, Reeve. Almost typical. Apparently 

 of extended distiibution : we have seen specimens from very widely 

 distant localities. 



18. Cancbllaria obliquata, Lam. In fine condition. 



19. Cancellaria Wilmeri, Sby. A small but interesting species, 

 discovered by Lieut. -Col. L. W. Wilraer, and described by Mr. G. B. 

 Sowerby in Proc Zool. Soc. 1881, p. 637. It is endemic, so far as at 

 present known, in Andamanese seas. 



20. Oliva AirsTRALis, Duclos. 



21. Oliva panniculata, Duclos. PI. XIII, Fig. 14. Mr. J. M. 

 "Williams, who has kindly compared our shell with specimens in his 

 own fine collection, pronounces it to be "a small but very nice 

 specimen oi pannictilataV 



22. Ancilla Booleyi, n.sp. PI. XIII, Fig. 13. 



A. testa oblongo-fusiformi, tenui, parura nitente, anfractibus 6, 

 apice mamillato, parvo, cfeteris la^vissimis, pallide cinereo-albis, infra 

 suturas rufis flammis depictis, ultimo anfractu rufis flammis fulgetrinis 

 ad f diametri decorate, et apud basim rufo-strigato ; apertura ovato- 

 oblonga, paullum effusa, labro simplice, columella planata. Long. 14, 

 lat. 5 mm. sp. maj. 



An interesting Ancilla, though amongst the smaller species of 

 this circumscribed genus. It somewhat recalls an Agaronia in the 

 disposition of its markings, being oblong, thin, six-whorled, pale 

 ashy-white, marked below the sutures and over the greater portion 

 of the last whorl with rufous spots, or zigzag markings. The mouth 

 is ovate-oblong, lip simple. We name it after its discoverer, Mr. G. H. 

 Booley, of Port Blair. 



23. Mitra (Chrysame) coriacea. Reeve. This species is very 

 uncommon. It is distinguished by its deeply impressed sutures, and
