CANCELLARIA. 



Species G8. (Fig. a, b, Mus. Cuming.) 

 Cancellaria funiculata. Can. testa acuminalu-turn- 

 td, umbilicald, spird gracili, anfractibm ad suiuram 

 profmidi impressis, obinse angulatis, longitudinaliter 

 costatis, costis elevatis, compressis, dktantibua, liris 

 exilibus transversis sculptis, lined elevatd inlerveniente ; 

 pellucido-albd, ouraiitio jjallidi tiiictd ; aperturd tri- 

 gono-ovatd, lahro expatiso, colnmelld tripUcatd. 

 TiiF, CORDED Cancellakia. Shell acuminately tnr- 

 reted, umbiliciited, spire slender, whorls deeply im- 

 pressed at the suture, obtusely angled, longitudinnlly 

 ribbed, ribs raised, compressed, distant, sculptured 

 with delicate transverse ridges, with a raised line in- 

 tervening; transparent white, faintly tinged with 

 orange ; aperture triangularly ovate, lip expanded, 

 columella three-plaited. 

 Hinds, Moll. Voy. Sulphur, p. 43. pi. 12. f. 5, 6. 



Cancellaria lyrata, Adams and lleeve. 

 Ilab. Gulf of Magdalena, California (in sandy mud, at 

 seven fathoms); Hinds. 

 Characterized by its exquisitely sculptured distant ribs, 

 which give the shell a Scalaria-WVe aspect. Although the 

 locality given by Sir Edward Belcher to C. lyrata of the 

 Voyage of the Samarang is China Sea, the species are evi- 

 dently the same. 



Species G9. (Fig. a, b, Mus. Cuming.) 



Cancei,L.\ki.4. Mangelioides. Can. testa acimiinato- 

 turritd, impcrforatd, spird acuta, anfractibm superne 

 angulatis, longitudinalitef costatis, costis compressis, 

 disiantiJjas, transversini striatis ; candidd ; aperturd 

 trigono-ovatd, labro subexpamo, coltimelld tripUcatd. 



The Makgelia-i.ike Cancellaria. Shell acuminately 

 turbinated, imperforated, spire sharp, whorls angled 

 round the upper part, longitudinally ribbed, ribs 

 compressed, distant, transversely striated ; white ; 

 aperture triangularly ovate, lip rather expatidcd, co- 

 lumella three-plaited. • 



Hab. ? 



Kesembling the ])rcccding species in some respects, but 



more compactly convoluled, and more obtusely angled 



round the upper pari of tiie whorls. 



Species 70. (Fig. fi, h, Mus. Cuming.) 

 CaNcellaiua tlssellata. Can.' testa cylindraceo-ob- 

 longd, soUdimculd, imperforatd, spird brevi, conicd, 

 suturd parmti impressd, anfractUms plano-convexis, 

 granoso-decussatis ; albidd, purpureo-ferrugineo fas- 

 ciatd et interdum tessellatd ; aperturd anguste oblongd 

 fatice liratd, colunielld valide biplicatd, late e?icaus- 

 ticd. 

 The tessellatkd Cancellakia. Shell cylindrieally 

 oblong, rather solid, imperforated, spire short, coni- 



cal, suture but little impressed, whorls flatly convex, 

 granosely decussated; -whitish, banded and some- 

 times tessellated with purple-rust ; aperture narrowly 

 oblong, ridged within, columella strongly two-plaited, 

 broadly enamelled. 

 SowERBY, Pro. Zool. Soc. 1833, p. .")1. 

 Ilab. Bay of Caraccas, St. Elena, and Xipixapi, Central 

 America (dredged from a sandy nmddy bottom, at a 

 depth of from seven to ten fathoms) ; Cuming. 

 Quite unlike any other species of the genus in its gene- 

 ral typical form, as is sufficiently apparent in the figure. 



Species 71. (Fig. a, h, Mus. Cuming.) 



Cancellaria foveolata. Can. testa pyramidali-ovatd, 

 anguste umbilicatd, spird exsertd, anfractibus ad su- 

 iuram profunde declivi-excavatis, ad angulum obtuse 

 carinatis, deinde plano-convexis, lavibus; carneo-fulvd, 

 lineis pallide fuscescentibus cingulatd, aurantio-fusco 

 ad angulum cingulatd ; aperturd trigono-ovatd, labro 

 crasse varicoso, columelld arcuatd, tripUcatd. 



The trenched Cancellaria. Shell pyramidally ovate, 

 narrowly umbilicated, spire exserted, whorls deeply 

 slantingly excavated at the suture, obtusely keeled at 

 the angle, then flatly convex, smooth ; flesh-fulvous, 

 encircled with faint brownish lines, blotched with 

 orange-brown at tlie angles ; aperture triangularly 

 ovate, lip thickly varicose, columella arched, three- 

 plaited. 



SowEKBY, Pro. Zool. Soc. 1848, p. 137. 



Hab. Algoa Bay. 



The excavated grooving of this species slants inward in 

 a peculiar manner, whilst the shell is characterized by a 

 faint linear pattern. 



Species 73. (Fig. a, b, Mus. Cuming.) 



Cancellaria corrugata. Can. testd oblcmgo-pyriformi, 

 imperforatd, spird cvsertd, subobtusd, anfractibus de- 

 clivi-convexis, longitudinaliter ob-iolete corrugatis, lineis 

 impressis decussatis ; fulvo-olivaced ; aperturd anguste 

 oblongd, fauce liratd, columelld subattenuatd, bipli- 

 catd. 



The wrinkled Cancellaria. Shell oblong pear-shaped, 

 imperforated, spire exserted, rather obtuse, whorls 

 slantingly convex, longitudinally obsoletely wrinkled, 

 decussated with impressed lines ; fulvous-olive ; aper- 

 ture narrowly oblong, ridged within, columella rather 

 attenuated, two-plaited. 



Hinds, I'ro. Zool. Soc. 1843, p. 48. 



Hab. Bay of Guayaquil (in mud, at the depth of seven 

 fathoms) ; Hinds. 



Of a veiy distinct typical form, peculiarly attenuated 

 towards the base, and having no excavated indenture at 

 the suture. 



December, 1856.
