 The whitish Cancellakia. Shell somewhat fusiformly 

 oblong, solid, imperforated, twisted at the base, spire 

 acuminated, whorls flatly convex, narrowly puckered

 Hinds, Pro. Zool. Soc. 1843, p. 47. 

 Hab. Bay of Guayaquil, Panama, andVeragua (at a depth 

 of from seven to twenty-three fathoms) ; Cuming. 



This elegantly fusiform species, collected by Mr. Hinds 

 in the voyage of the ' Sulphur,' is most exquisitely latticed 

 throughout with equidistant raised cord-like ridges. 



spire sharply acuminated, whorls rounded, but little 

 flattened at the suture, densely nodosely reticulated 

 throughout ; white ; aperture rather narrow, strongly 

 ridged within, plaits two, strong, very prominent. 



SowERBY, Conch. Illus. sp. 2. f. 1. 



Uab. Polynesia. 



This species very closely resembles C. austraiis, but it 



may be at once recognized by its stronger sculpture, and 



more prominent columellar plaits. 



Species 47. (Fig- a, b, Mus. Cuming.) 



Cancellakia venteicosa. Can. testd fusiforMi-oblongd, 

 ventricosd, imperforatd, spird acute acuminatd, an-

 liris longitudinalibus et spiralibus undique decussatis ; 

 rufo-fuscd; plicis tribtcs, angustis. 



The ventbicose Cancellakia. Shell fusiformly ob- 

 long, ventricose, imperforated, spire sharply acumi- 

 nated, whorls flatly convex at the upper part, then 

 rounded, decussated throughout with longitudinal 

 and spiral ridges ; red-brown ; plaits three, narrow. 



TIiNDs, Pro. Zool. Soc. 1843, p. 47. 



Hab. Pvealejo, Central America (at a depth of from sixty 

 to seventy fathoms), and Gulf of Magdalena, Cali- 

 fornia (in sandy mud at seven fathoms) ; Hmds. 

 Not much unlike C. albida, but of a peculiar red-brown 



colour, carved with a distinct pattern of sculpture. 



Species 46. (Fig. a, b, Mus. Cuming.) 

 Cancell.oia CANDIDA. Can. testd siibfusiformi-ovafd, 

 ventricosd, Ijad contortd, imperforatd, spird acute acu- 

 minata, anfraciibus rotundatis, ad suturam parum 

 planatis, mdique denae nodoso-reticulatis ; Candida; 

 aperlurd subangustd, fauce valide liratd, plicis duabus, 

 fortibus, valdi prominentibas. 

 The white Cancellakia. Shell somewhat fusiformly 

 ovate, swollen, imperforated, twisted at the base. 



Species 48. (Fig. a, b, Mus. Cuming.) 



Cancellakia gemmulata. Can. testd ghboso-ovatd, so- 

 lidd, imperforatd, spird brevi, acuta, anfraciibus su- 

 perne vix angulatis, plano-convexis, costis nodulatis^ 

 Urisque dense conspicue decussatis; albd ; aperlurd 

 subexpansd, plicis tribus, mediocribus. 



The gemmed Can cellabia. SheU globosely ovate, solid, 

 imperforated, spire short, sharp, whorls scarcely angled 

 at the upper part, flatly convex, closely prominently 

 decussated with noduled ridges; white; aperture

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



Hai. Bay of Nicoiya, Central America (from a sandy 

 muddy bottom) ; Cuming. 

 Distinguished from the preceding species chiefly by 



its more contracted subglobose form and roughly noduled 



sculpture.
