 A solid rudely sculptured shell, with a characteristic 



bright-red aperture. 



Species 31. (Fig. a, b, Mus. Cuming.) 

 Cancellaria chrysostoma. Can. testd subglobosd, vix

 The golden-mouth Cancellaria. Shell subglobose, 

 scarcely umbilicated, spire subpyramidal, whorls but 

 little angled at the upper part, rudely decussated 

 with thick ribs and ridges; bluish-white, sparingly 



dotted and lineated with chestnut ; aperture ro- 

 tundatcly expanded, interior ridged and wrinkled,

Sowerby, Pro. Zool. Soc. 1832, p. 54, 



Hab. Panama and St. Elena (dredged from a sandy bottom, 



at the depth of from eight to ten fathoms) ; Cuming. 



Obscurely rudely decussated with ribs and ridges, and 



with a more expanded aperture than the preceding species. 



Species 32. (Fig. a, b, Mus. Cuming.) 



Cancellaria goniostoma. Can. testd subglobosd, am- 

 pliter profundi umbilicatd, spird turritd, anfractibus 

 superne latissime excavato-angulatis, longitudinaliter 

 costatis, costis distantibus, liris spiralibus clathratis ; 

 purpurascente-albd, castaneo-fusco hie illic lineatd; 

 aperturd parvd, trigond, plicis duabus, subobsoletis. 



The angle-mouth Cancellaria. Shell subglobose, 

 largely deeply umbilicated, spire turreted, whorls 

 very broadly excavately angled at the upper part, 

 longitudinally ribbed, ribs distant, latticed- with spiral 

 ridges ; purple-white, here and there lineated with 

 cliestnut-brown ; apertm-e small, triangular, plaits 

 two, rather obsolete. 



Sowerby, Pro. Zool. Soc. 1832, p. 51. 



ffab. Conchagua and St. Salvador, Central America 

 (dredged from a sandy bottom, at a depth of about 

 eight fathoms) ; Cuming. 

 This fine species is characterized by its broadly angled 



turreted growth and bold latticed sculpture. 



Species 33. (Fig. a, b, Mus. Cuming.) 



Cancellaria rigida. Can. testd ovatd, subavipliter pro- 

 funds umbilicatd, spird turritd, anfractibus supems 

 late excavato-angulatis, oblique costatis, costis tenuibus, 

 subdistantibus, liris subtilibus spiralibus decussatis; 

 luteo-spadiced, ad angulum purpureo-fuseo maculatd; 

 aperturd trigond, ad basin sinuatd, triplicatd. 



The rigid Cancellaria. Shell ovate, rather largely 

 deeply umbilicated, spire turreted, whorls broadly 

 excavately angled at the upper part, obliquely ribbed, 

 ribs thin, rather distant, decussated with fine spiral 

 ridges; yellowish-fawn, spotted at the angle with 

 purple-brown; aperture triangular, sinuated at the 

 base, plaits three.

 Cancellaria costata, Sowerby, Jun. 



Rab. Puerto Portrero, Central America (from a sandy 



bottom, at the depth of thirteen fathoms) ; Cuming. 



This species comes near to C. goniostoma in form, but 



is at once distinguished by its more delicate ribs.
