BiLLiA DIGITALIS. Bid. testd acmninato-turrita, hmem 

 versus gradatiiii effiisd, truncatd, splrte sutiem suhcallo- 

 sis, lined spirali incisis ; anfractibiis leevibus, lilt'mio

 Bidlia achatina. Gray. 



Uab. ? 



We are indebted to the accuracy of Mi'. Dillwyn for 

 showing this to be tlie Biiccinum digitnle of Meuschen, 

 though it is probable one or two of its congeners were 

 confounded with it under the same title. The specific 

 name attachedto it by Lamarck is doubly inapplicable, 

 on account of the term Buccinum achaiimim havuig been 

 already given by Midler and others to the type of Ids 

 genus Achatina (J.perdix). 



Species 14. (Brit. Mus.) 



Bullia sulcata. Bid. testd acuminato-turritd, basi siib- 

 effnsd, anfractibus concentrice creberrime undidato-sul- 

 catis ; carideo-plumbed. 



The grooved Bullia. Shell acuminately turreted, some- 

 what eifused at the base, whorls concentrically very 

 closely undulately grooved ; blueish lead colovu'. 



Ilab. ? 



A peeidiarly dark blueish lead-coloured shell of rather 

 solid structure, very closely concentrically grooved tlu'ough- 

 out. 



Species 33. (Mus. Cuming.) 



Bullia semiusta. Bid. testd acuminato-turritd, basi 

 truncatd, lavigafd, politd ; anfractibus supra albidis, 

 infra ustidaio-fuscis, columella eburned. 



The half-scorched Bullia. Shell acuminately tur- 

 reted, truncated at the base, smooth, polished ; whorls 

 white above, burnt brown below, columella ivory- 

 white. 



Hal). ? 



Distinguished in form, as well as by its peculiar contras 

 of colomine. 



Species 23. (Mus. Brit.) 



Bullia cochlidium. Bid. testd ovato-iurritd, tenuindd, 

 anfractibus superne rotundatis et subcanalicidatis, Itevi- 

 biis, colmnelld arcnatd ; palUde fidvd. 



The windixg-stair Bullia. ShoU ovately turreted, 

 rather thin, whorls rounded and somewhat channelled 

 round the upper part, smooth ; columella arched, 

 pale fulvous yellow. 



Buccinum cochlidium, Chemnitz, Conch. Cab. v. 11. p. 275. 

 pi. 209. f. 2053, 4. 



Hab. ? 



It may be observed that a considerable portion of the 

 shell here represented is broken away, but I value it as 

 enabling me to confirm the view taken by M. Deshayes, 

 that the Buccinum cochlidium of Chemnitz, with whose 

 figure tliis specimen accords, is specifically distinct from 

 the Bullia gradata ivith wliich it has been hitherto con- 

 founded. 



Species 24. (Mus. Gray.) 



Bullia callosa. Bui. testd acuminata, basem versm 

 gibbosd et eJfuM, spiro' suturis suhprofundin, anfractibus 

 lavibus, colmnelld arcuatd, truncatd, caUositate ampld 

 munitd; caruleo-fuscescerde, caUositate eburned, pur- 

 pureo-fusco tinctd. 



The callous Bullia. Shell acuminated, gibbous and 

 effused towards the base, sutures of the spire rather 

 deep, more or less callous ; whorls smooth, columella 

 arched, truncated, furnished with a large callosity ; 

 blueisli-brown. 

 Buccinum callosum. Wood. Ind. Test. Supp. 



Eab. ? 



Eemarkable for the callous deposit of enamel which 

 overspreads the colunieUa and a considerable portion of the 

 bodv-whorl.
