coating of enamel, which also forms a mass on the upper angle of 

 the aperture; this enamel is likewise continued as a belt across the 

 shoulder of the body whorl ; the base of the shell has two thickened 

 belts ; the upper of which is chestnut, and margined above by 

 a narrow white band, in which are two slender grooved lines ; the 

 middle of the body whorl is pale yellowish above, and deep chest- 

 nut beneath; the shoulder belt and the spire are also chestnut, with 

 two white bands ; the tip of the spire, the aperture, and the callosity 

 above it, are pure white; base of the pillar but slightly thickened, 

 and faintly striated by two grooves ; outer lip one-toothed. This 

 rare species is probably found at the Cape of Good Hope. Two 

 specimens were in the African Museum, and are now in the cabinet 

 of Mr. Broderip. 



11. Ancillaria Tankervillii. Sp. Nov. Mihi. 



A.iesla imperforatd, oblonga, flavescente ; spird elongatS, lined jtucta 



suluram levatd : bast svlcatd. 

 Shell imperforate, obloDg, yellowish ; spire elongated, with an elevated 

 line near the suture ; base grooved. 



A single specimen of this exceedingly rare shell exists in the 

 Tankerville collection; from which the above specific character 

 was hastily noted down, while inspecting that magnificent cabinet 

 last year. In size and proportions it perfectly resembles the An- 

 cillaria glabrata (Buccinum glabratum, Lin.) yet, like the next spe- 

 cies, has not the least vestige of an umbilicus. It is clearly dis- 

 tinguished from A. rubiginosa by the elevated line which follows the 

 suture. We may expect the imperfections of this description to 

 be soon supplied by Mr. G. Sowerby, in the catalogue of this noble 

 collection, now preparing for publication.
