much more contracted ; the black does not descend so low on the 

 occiput ; the back is rather darker in hue ; while, instead of a broad 

 pectoral band of deep black extending from the white throat to the 

 abdomen, there is merely a narrow black gorget between the throat 

 and the breast. I propose therefore to describe the species as 



Campicola livingstonii, n. sp. 



Campicolae pileato similis, sed ininor : fronte vix albo nofata : 

 capitis colore nigro non in occiput descendente : tergo cinna- 

 momeo-fusco : gula alba, zona nigra contractu a pectore divisa, 

 nerpie scuto laio nigro, lit in C. pileato : pectore albo, in rnfo- 

 cinnamomeum descendente : abdomine, lateribus, candaque sic 

 ut in C. pileata. 



Long, tota 6 poll., alee 3'7, caudae 2*5, rostri a rictu 7, tarsi 

 1-1.5.

(Plate XLIII.) 



1. Geotrochus gamelia. (PI. XLIII. figs. I, 2, 3.) 



Shell imperforate, flatly conical, thin, obliquely, faintly, and irre- 

 gularly plicately striated, white, rather broadly banded with dark 

 brown at the suture and periphery, the lower edge of the sutural 

 band sometimes diffused and paler, and with a spiral band of the 

 same colour at the base ; spire conical^ rather obtuse at the apex ; 

 whorls five, nearly flat, the last more or less descending, subangulate 

 at the periphery, convex at the base ; columella sloping, moderately 

 wide ; aperture diagonal, truncately oval ; peristome thin, the mar- 

 gins distant, the right flexuous and slightly expanded, the basal 

 slightly reflexed. 



Fariety. With the basal band very broad, columella and lip 

 brown, and an additional narrow band on the three lower whorls.

Hub. St. Stephen Island and Ysabel Island, Solomon group. 



2. Geotrochus eros. (PI. XLIII. figs. 4, 5, 6.) 



. Shell umbilicated, subtrochiform, rather solid, obliquely striated, 

 on the last whorl decussated with very fine sloping rugose striae, pale 

 fawn-colour, banded with white at the periphery, and ornamented 

 with two rows of irregular chestnut blotches; spire conoidal, apex 

 rather obtuse and rose-coloured ; whorls four and a half, slightly 

 convex, the last a little descending, keeled at the periphery, convex
