Species 13. (Fig. 13. i, and 13. f, J\'Ius. Cuming.) 

 DoLiUM CuMiNGii. Dol. testa globoso-ovatd, tenui, ven- 

 iricosd, umhllkatd, aufractibm septem, transversim 

 nmUicodatis, costis depresso-planis, confertis, interditiis 

 Uneari-sulcatis, columella subcontortd, labro simplici; 

 fulvo-castaued, macul'm fuscis et alhis fasciatim pectc- 

 I'mriter nebulatd. 

 Cuming's Tun. Shell globosely ovate, thin, ventricosc, 

 umbilicated, whorls seven in number, transversely 

 many-ribbed, ribs depressly flattened, close-set, inter- 

 stices linearly grooved, columella slightly twisted, lip 

 simple ; fulvous chesnut, peculiarly clouded in a 

 banded manner with brown and white spots.

This is unquestionably distinct both from the J), olea- 

 rium and Deshai/em. Characterized in great measure by its 

 globose form, it is also distinguished by its'Vtyle of painting 

 which is very peculiar, and, as in all the species of the 

 genus, a constant and not unimportant feature.

DoLiUM OLEARIUM. Dol. tenia ovatd, ve)it>ico.srssi„i, 

 umbilicatd, spirce suturk caiialiculatk, anfractib,

 The oil-jar Tun. Shell ovate, extremely ventricose, 

 umbilicated, sutm-es of the spii-e channelled, whorls 

 seven iu number, transversely ribbed, ribs flatly de- 

 pressed, rather broad, close set, interstices linearly 

 grooved, lip simple ; fulvous chesnut, sprinkled with 

 conspicuous white spots.

BucciiiMM oleurium, Bruguiere. 

 Hob. Ceylon. 



This is the Biiccimim olearium of Bruguiere, but not of 

 Linnaeus, which accounts for his remark in the Encyclo- 

 pedic Methodique : " J'ignore ce que Linue a entendu par 

 les mots ' siilcis obiusis Utieold elevald intersti/ictis,' qu'il a 



employe dans la difference specifiquc de ce Buccin, puisque 

 ses cotes, de meme que ses sillons, n'offrent pas des lignes 

 elevees." The shell upon which Linnseus founded his 

 Bttccinum olearium, preserved in the museum of the 

 Linneean Society of London, proves on examination to be 

 notliing more than a very young specimen of the D. galea, 

 in the early growth of wliich species there is always a fine 

 elevated line in the interstices of the upper ribs. 



From an observation of two young individuals of the 

 Lamarckian Dolium olearium in the same collection, I am 

 inclined to think Linna;us' Bulla canaliculala, which has 

 never been identified, is tliis shell ; there is, however, one 

 point in which the description of that species in the 

 ' Systema Naturae ' does not agree, namely, in respect of 

 form, "cyUndrica." For this reason the name olearium, 

 with the above explanation, may be retained. 



Species 15. (Fig. 13. a, Mus. Cuming.; 



Dolium Deshayesii. Dol. testa subgloboso-oblongd, vix 

 umbilicatd, spird mmquam canaliculatd, anfractibiis sex, 

 spiraliter lineari-mlcatis, labro simplici ; pallide ful- 

 vescente-castaned, maculis compicuia albis, fusco-um- 

 bratk, plerumque hinis, subdistantihis fasdatim pictd. 



Desiiayes' Tun. Shell somewhat globosely oblong, 

 scarcely umbilicated, spire never channelled, whorls 

 six in number, spirally linearly gi-ooved, lip simple, 

 pale fulvous chesnut, painted with bands of rather 

 distant conspicuous white spots, shaded with browii, 

 and ranging mostly in pairs. 



Sab. Philippine Islands ; Cuming. 



A comparison of this shell with the Lamarckian BoUum 

 olearium enables me to confirm the accuracy of M. Deshayes' 

 observation (Anim. sans vert. nov. edit. vol. x. p. 140. note) 

 to the "fleet, that the specimen figui-ed for that species by 

 Mr. So, -irby in his 'Genera of Shells,' and by myself, 

 from the Same engraving, in ' Conchologia Systematica,' is 

 distinct fro> i it. The sutm-es of the spire are not chan- 

 nelled, and I'lere is a singular peculiarity in the style of 

 colouring, ben g painted with white blotches, shaded with 

 brown, ranging two and two in distant bands, or in bands 

 longitudinally. The figure in ' The Genera ' gives a cha- 

 racteristic view of the back of the species.
