CANCELLARIA. 



Species 21. (Fig. a, h, Mus. Cuming.) 

 Cancell.\uia ckenifeka. Can. testa snbpyramidali, 

 profumle umiilicatd, spird acuminata, anfractibus ad 

 suturam plano-excavatis, deinde oblique ecstatic, costis 

 ad angulum, muricato-uncinaiis, spiraliter crenato-li- 

 ratis; iivido-spadieed, liris albidis ; aperturd parvd, 

 fance incrassatd, plicis tribu.% niediocribus. 

 The crenated Cancellaeia. Shell subpyramidal, 

 deeply umbilicated, spire acuminated, whorls flatly 

 excavated at the suture, then obliquely ribbed, the 

 ribs prickly hooked at the angle, spirally crenately 

 ridged; livid fawn, ridges white; aperture small,

p. 453. pi. 96. f. 84 to 86. 

 Hab. Bay of Manila (in sandy mud at the depth of five 

 fathoms) ; Cuming, 

 This elegantly formed species is peculiarly characterized 

 by the prickly-hooked termination of the ribs, which are 

 crenated throughout with white cross-ridges. 



Species 25. (Fig. a, b, Mus. Cuming.) 

 Cancellaria scalarina. Can. testa pyramidali, vix 

 umbilicatd, spird acuniiuato-turritd, anfractibus ad 

 suturam ampliter excavatis, acute angulalis, oblique 

 coslatis, costis angustis, disiantihis, ad angulum ele- 

 vatis; fulvo-spadiced, alio-faseiatd ; aperturd parvd, 

 plicis tribtts, parvis. 

 The LAUDER Cancellaria. Shell pyramidal, scarcely 

 umbilicated, spire acuminately turreted, whorls largely 

 excavated at the suture, sharply angled, oblicjuely 

 ribbed, ribs narrow, distant, raised at the angle ; ful- 

 vous-fawn, banded with white; apert\ire small, plaits 

 three, small. 

 Lamarck, Anim. sans vert. vol. iv. p. 403. 

 Hab. West Indies. 



It is not possible to determine, satisfactorily, which spe- 

 cies is the Lamarckian C. scalarina. The shell here figured 

 is that assigned to it by Mr. Sowerby. 



Species 26. (Fig. a, b, Mus. Cuming.) 

 Cancellaria melanostoma. Can. te-Hd ocatd, siibpen- 

 tricosd, imperforald, spird brevimculd, acuminata, an- 

 fractibus convexis, liris subtilibm undique dense decus- 

 satis ; fulvescenfe-albd, rvfo-fusco linctd et faiciatd ; 

 aperturd ovatd, columelld subexcavatd, late encausticd, 

 purpureo-fuscd, plicis tribus, niediocribus. 

 The black-moutu Cancellaria. Shell ovate. 



ventricose, imperforated, spire rather short, acumi- 

 nated, whoris convex, closely decussated throughout 

 with fine ridges ; fulvous-white, stained and banded 

 with red-brown ; aperture ovate, columella somewhat 

 excavated, broadly enamelled, purple-brown, plaits 

 three, moderate.

Hab. ? 



Chiefly distinguished by its wide-spread enamelled la- 

 mina around the columella, of a dark purple-brown colour. 



Species 27. (Fig. a, h, Mus. Cuming.) 

 Cancellaria bifasoiata. Can. testa fusiformi-obhngd, 

 ad basin attenuatd, imperforatd, spird exsertd, anfrac- 

 tibus plam-convexis, liris parvis confertis midique 

 dense decussatis ; rufescente-spadiced, faseiis duabus 

 pallidis cingulatd; aperturd oblongo-omtd, columelld 

 arcuatd, triplicatd. 

 The two-banded Cancellaria. Shell fusiformly ob- 

 long, attenuated at the base, imperforated, spire ex- 

 serted, whorls flatly convex, densely decussated with- 

 out with small close-set ridges; reddish-fawn, en- 

 circled with two faint bands ; aperture oblong-oval, 

 columella arched, three-plaited. 

 Deshayes, Enc. Meth. Vers, vol. ii. p. 181. 



Cancellaria oblonga, Kiener. 

 Hab. Straits of Macassar (in coarse sand) ; Hinds. 



The short description of C. oblonga in the Appendix to 

 the Tankerville Catalogue does not agree with this fusi- 

 form Mitre-\k.t species. 



Species 28. (Fig. a, b, Mus. Cuming.) 



Cancellaria textilis. Can. testa subpyramidaU, sub- 

 umbilicatd, spird aeuminato-turritd, aiifractibtts ad 

 suturam impresso-excavafis, deinde oblique longitudi- 

 naliter costatis, liris spiralibus subobscuris decussatis ; 

 rufo-castaned, super castas hie illic albipunctatd ; aper- 

 turd parvd, plicis tribus, niediocribus. 



The textile Cancellaria. Shell subpyramidal, slightly 

 umbilicated, spire acuminately turreted, whorls im- 

 pressly excavated at the suture, then obliquely longi- 

 tudinally ribbed, decussated with faint spiral ridges ; 

 reddish-chestnut, here and there white-dotted on the 

 ribs ; aperture smaU, plaits three, moderate.

Hab. Moluccas. 



An elegant species, conspicuously distinguished by its
