 p. 4.55. pi. 93. f. 36. 



Hub. Ceylon; Dr. Siebold. 

 Sculptured throughout with delicate close-set ribs, finely 



noduled at distant intervals, the shell being of a subtrans- 



parent pinkish-fawn colour, inclining more to rose towards 



the apex. 



Species 20. (Fig. a, b, Mus. Cuming.) 



Cancellaria granosa. Can. testa subpyramidali, ob- 

 tecte umbilicatd, spird acuminato-turritd, anfractibus 

 superne anguste planatis, deindi longitudinaliter cos- 

 tatd, liris obtuse granatis spiraliter decussatis ; Jh- 

 vescente-spadiced, rufo sparsim macidatd ; aperturd 

 parviusculd, plicis tribua, parvis. 



The grained Cancellaria. Shell subpyramidal, with 

 a convex umbilicus, spire acuminately turreted, whorls 

 naiTOwly flattened round the upper part, then longi- 

 tudinally ribbed, spirally decussated with obtusely 

 grained ridges ; yellowish-fawn, sparingly blotched 

 with red ; aperture rather small, plaits three, small. 



Sowerby, Conch. lUus. f. 16, 17. 



Hab. Peru. 



The surface of this species is but indistinctly obtusely 



grained, of a yellowish-fawn colour, sparsely blotched 



round the angle of the whorls with reil. 



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



Cancellaria Eburnvepormis. Can. lestd oblongd, im- 

 perfoi-atd, spird acmninalo-exsertd, anfractibus superne 

 leviter concavo-impreasis, deinde convexis, striis im- 

 pressis undique decussatis; albidd, ferrugineo-nifo 

 tinctd et fasciatd; aperturd subangustd, fauce valide 

 lirald, plicis duabus, tenuibus, prominentibus. 



The Eburna-shaped Cancellaria. Shell oblong, im- 

 perforated, spire acuminately exserted, whorls slightly 

 concavely impressed round the upper part, then con- 



vex, decussated throughout with impressed striae ; 



whitish, banded and stained with rust-red ; aperture 



rather narrow, interior strongly ridged, plaits two, 



thin, prominent. 



Eab. ? 



This species partakes of the characters of C. reticulata 

 and acuminata, but is distinctly characterized by the more 

 acuminated convolution of the spire, and more globose 

 form of the body-whorl. 



Species 22. (Fig. a, b, Mus. Cuming.) 



Cancellaria decussata. Can. iestd globoso-fusiformi, 

 oblecte umbilicatd, spird breviusculd, acuta, anfracti- 

 bus ad suturam subimpressis, liris funicnlatis undique 

 cancellatis ; fulvescente ; aperturd subangustd, plicis 

 trihus, mediocribus. 



The decussated Cancellaria. Shell globosely fusi- 

 form, with a covered umbilicus, spire rather short, 

 sharp, whorls slightly impressed at the suture, can- 

 cellated throughout with corded ridges ; fulvous ; 

 aperture rather narrow, plaits three, moderate. 



Sowerby, Pro. Zool. Soc. 1832, p. 55. 



Rab. Panama (dredged from a sandy bottom, in ten to 

 thirteen fathoms) ; Cuming. 

 Of a somewhat Triton-Yike form, openly reticulated 



throughout with rather distant narrow raised cords. 



Species 23. (Fig. a, b, Mus. Cuming.) 

 Cancellaria urceolata. Can. testa subfusifurmi-tur- 

 ritd, solidiusculd, imperforatd, spird exsertd, anfrac- 

 tibus superne anguste obtuse angulatis, deinde piano- 

 convexis, oblique longitudinalitm- corrugato - liratis, 

 sulcis spiralibus linearibus decussatis ; fuleescente- 

 stramined ; aperturd parviusculd, pUcis duabus, an- 

 gustis, subprominentibus. 

 The urceolate Cancellaria. Shell somewhat fusi- 

 formly turreted, rather solid, imperforated, spire ex- 

 serted, whorls narrowly obtusely angled, then flatly 

 convex, obliquely longitudinally wrinkle-ridged, de- 

 cussated with spiral linear grooves ; fulvous straw- 

 colour; aperture rather small, plaits two, narrow, 

 rather prominent.

 Hab. Gulf of Papagayo and San Bias (in seven to fourteen 

 fathoms); Hinds.

 cellated with oblique longitudinal waved ridges and spiral 

 linear grooves.
