BULLIA. 



Plate I. 



Genus Bullia, Gniy. 



Testa ovalo-tiirrUa, spird mhulato-acmuinatd, spireB siilurk 

 nunc impressis, nunc callosis ; columelld plus minusve 

 callosd, labro sapissime slvipUci, aperturdbad late emar- 

 ginatd; lutescente aid pallide Uvidd. 



.Sliell ovately tuiTcted, spire subulutely acuminated, sutiu'es 

 of the spire sometimes impressed, sometimes callous ; 

 columella more or less caUons, lip mostly simple, 

 aperture widely emarginated at the base ; yellowish 

 or pale livid colour. 



The genus Bullia was founded by Mi\ Gray for the 

 purpose of distinguishing a very natm'al gi'ouj) of species, 

 intermediate between Buccinum and Terebra, and of which 

 the Buccinum. lari-ssinuDn and Terebra vittata of Lamarck, 

 may be regarded as tj-pifpng a peculiarity of character 

 fully borne out by a difference in the animal, which, ac- 

 cording to the representations of MM. Quoy aiul Gaimard, 

 is remarkably characterised by the wide expansion of its 

 ventral disc. 



Of the midtifarious genera enumerated by Mi-. Gray in 

 his ' Synopsis of the Collection of the British Museum ", 

 few are more deserving of attention than the present, 

 introduced in his ' Zoology of Becchey's Voyage of the 

 Blossom "; not only are the shells distingiushed by a subu- 

 late tm-reted growth, different from that of any Terebra, 

 and are for the most part of a curious callous formation, 

 but they possess a livid peculiarity of colom-ing and texture 

 which assumes a certain decree of generic importance. 



Tlie species at present known are about two- or three- 

 and twenty in number', several of which have been con- 

 founded together, for want of investigation, under similar 

 names. They do not appear to be confined to any parti- 

 cular locality ; in respect to their habits, the author notices 

 that tliey " are found crawKng on the sand in bays; they 

 j2;eiierally remain at the bottom of the water, and are easily 

 caught aUve with a bit of meat tied at the end of a string> 

 as they immediately attach themselves to it."

The thin Bullia. Shell rather thin, sharply turreted, 

 veutricose towards the base, sutm'es of the spii-e

 several fine grooves below and a single minute one 

 above, apertm'e rather wide ; didl white.

Ilab. ? 



A thin delicate species, comparatively smooth, and white.

 nentibus submucronatis irreguJaribus ad angulum arma- 

 tis ; columelld superne callosd; albidd,fa^ciis duabus 

 rufo- vel caruleo-fuscis latimculis ornatd. 



The AHMED Bullia. SheU turreted, sutures of the spu'c 

 callous ; whorls angularly slanting round the upper 

 part, armed at the angle with irregular prominent 

 pointed nodides ; columella callous at the upper part ; 

 whitish, ornamented with two rather broad reddish 

 or blueish-brown bands.

Halj. ? 



EasUy distinguished from any other species at present 

 known, by the armature of elevated nodules with which 

 the whorls are coronated. 



Species 3. (Mus. Cuming.) 



Bullia geadata. Bui. testa ovatd, crassinsculd, spird 

 exsertd, suturis callosis; anfractibus superne depresso-

 rufo-fusco Ilia illic longitudinaliterflammatd. 



The step Bullia. Shell ovate, rather thick, spii-e ex- 

 serted, sutures callous ; whorls depressly flattened 

 round the upper part, margined with a rounded ledge, 

 smooth throughout; columella callous above; pale 

 yellowish bay, longitudinally flamed here and there 

 with reddish-brown.
