Species 58. (Fig. a, b, Mus. Cuming.) 

 Cancellakia semi-disjuncta. Can. testa ovatd, latk- 

 sinie aperte umbilicatd, spird laxe exsertd, anfractibus 

 ad suturam latissumi excavate angulatis, angulo obtuso, 

 spiraUter liratk et excavate sulcatis, liris mlcisque

 The half-disjoined Cancellaria. Shell ovate, very 

 broadly openly umbilicated, spire loosely exserted, 

 wliorls very broadly excavately angled at the su- 

 ture, angle obtuse, spirally ridged and excavately

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

 Hab. Cagayan, Island of Mindanao, Philippines (from 

 sandy mud at the depth of twenty-five fathoms) ; 

 Cuming. 

 Readily distinguished by its loose manner of convolu- 

 tion, the last whorl being nearly disjoined from the pre- 

 ceding. 



Species 59. (Fig. a, b, Mus. Cuming.) 



Cancellaria Verreauxii. Can. testd ovatd, minute um- 

 bilicatd, spird breviusculd, acutd, anfraclibus convexia, 

 ad suturam angusti obtuse excavatis, longitudinaliter 

 oblique costatis, striis elevatis spiralibus decimatis ; 

 caataneo-rufd ; aperturd ovatd, fauce liratd, pUcis tri- 

 bus parvis. 



Vekreaux's Cancellaria. Shell ovate, minutely um- 

 bilicated, spire rather short, sharp, whorls convex, 

 narrowly olUusely excavated at the suture, longitudi- 

 nally obliquely ribbed, decussated with spiral raised 

 stria3 ; chestnut-red ; aperture ovate, interior ridged, 

 plaits three, small.

Hab. ? 



Allied, both in respect of form and colour, to C. Litlo- 



riiupfurmis, but more proniiueutly sculptured. 



Species 60. (Fig. a, b, Mus. Cuming.) 

 Cancellaria rugosa. Cuii. testd subglohosd, solidd, im- 

 perforald, anfractibus rotundatis, supeme obtuse angu- 

 latis, oblique rude tuberculato-costaiis, spiraUter sul- 

 catis; pallide gfrandned, ad angulum aurantio-rufo 

 tinctd; aperturd ovatd, subexpansd, fauce valide liratd, 

 columelld triplicatd. 

 The wrinkled Cancellaria. Shell subglobose, solid, 

 imperforated, whorls rounded, obtusely angled round 

 the upper part, obliquely roughly tubercuiarly ribbed, 

 spirally grooved ; pale straw-culour, tinged with 



orange-red at the angle; aperture ovate, rather ex- 

 panded, interior strongly ridged, columella three- 



Lamarck, Anim. sans vert. vol. ix. p. 408. 

 Hab. China. 



The form of this species is nearly globose, the shell 

 being expanded, so to speak, by its rude swollen tubercu- 

 lated ridges. 



Species 61. (Fig. a, b, Mus. Cuming.) 



Cancellaria OBLiaUATA. Can. testd oblique globosd, 

 ventricoso-expansd, angusie profundi umbilicatd, spird 

 parvd, acutd, anfractibus ad suturam sublate excavatis, 

 deinde rotundatis, oblique tenuicostatis, spiraUter ele- 

 vato-striatis, striis super castas nitide nodulatk, costis 

 ad angulum submuricatis ; fulvescente-albd, rufo-fus- 

 cescente tinctd et sparsim punctatd ; aperturd expan- 

 sd, fauce liratd, labro columellari tame reJle.co, plicit 

 tribus. 



The oblique Cancellaria. Shell obliquely globose, 

 ventricosely expanded, narrowly deeply umbilicated, 

 spire small, sharp, whorls rather broadly excavated 

 at the suture, then rounded, obliquely thinly ribbed, 

 spirally elevately striated, stria? neatly noduled on 

 the ribs, ribs slightly prickled at the angle ; fulvous- 

 white, stained and sparingly dotted with red-brown ; 

 aperture expanded, interior vidged, columellar lip 

 thinly reflected, plaits three. 



Lamarck, Anim. sans vert. vol. ix. p. 408. 



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

 fathoms) ; Cuming. 

 A most elegantly-formed neatly sculptured species, of a 



delicate, shining, fulvous-white colour, sparingly tinged 



and dotted with reddish-brown. 



Species 62. (Fig. a, b, Mus. Cuming.) 

 Cancellaria Littgrin^formis. Can. testd ovatd, pro- 

 fundi umbilicatd, tenuiculd, anfractibus supeme anguste 

 angulatis, deinde declivi-convexis, undique decussutim 

 strlatis ; rufescente-castaned ; aperturd subunguste 

 ovatd, columelld triplicatd. 

 The Littorina-likb Cancellaria. Shell ovate, deeply 

 umbUicated, rather thin, whorls narrowly angled at 

 the upper part, then slantingly convex, decussately 

 striated throughout; reddish - chestnut ; aperture 

 rather narrowly ovate, columella three-plaited. 

 SoWERBY, Conch. lUus. f. 14. 

 Hab. Ceylon. 



Of precisely the typical form of Litlorina, faiutly sculp- 

 tured throughout with decussating stria;.
