The peppered Makginella. Shell rather obtusely 

 conical, yellowish ash-colour, copiously freckled with 

 small black spots and dots, encircled with line hair- 

 lines, whorls gibbously-angied round the upper part, 

 lip thickened, conspicuously spotted with black.

Hub. Natal, East Africa. 



Allied to J/, rosea, but of a more obtusely conical form, 

 plentifully freckled throughout with black spots aud dots, 

 while there is a perceptible banding of fine hair-liues. 



Species 12. (Pig. a, b, Mus. Cuming; Fig. c, JIus. 

 Taylor.)

The mosaic ]\Iakginklla. Shell shortly conical, white, 

 cloudedly tessellated or filleted with olive-green, spire 

 rather obtuse, whorls ventrieosely angled round the 

 upper part, lip moderately reflected ; aperture rather 

 open.

Hub. East Africa. 



Though bearing a strong general resemblance to M. 

 pyrum, this is really a very distinct species. It is of a 

 shorter conical form, more ventrieosely angded, witii the 

 painting tessellated or disposed in transverse fillets. Be- 

 sides the two specimens here figured from Mr. Cuming's 

 and Mr. Taylor's collections, there is a particularly fine 

 specimen in the collection of Mrs. De Bnrgh. 



Species 13. (Fig. a, b, Mus. Taylor; Fig. c, Mus. 

 Cuming.) 



Makginella pyuuji. Marg. testa pyriforml-ovatd, al- 



bidd, lineis griseis, ad laliis umbratis, longitudinaliter 

 iuterruple imdaiis, spird promhiidd, anfractibus su- 

 penie declivi-aiigulalis, labro modice inerassato. 



TuE peak Makginella. Shell pyriformly-ovate, whitish, 

 longitudinally - irregularly interruptedly waved with 

 grey lines, shaded at the side, spii-e rather prominent, 

 whorls slopingly angled round the upper part, lip 

 moderately thickened.

 Marginella nubeculata, Lamarck. 

 Margiuella pijrum, Deshayes. 



Hab. East coast of Africa. 



This species, better known luider Lamarck's name of 

 nubeculata, was clearly named pyrum half a century be- 

 fore by Gronovius. He did not use the binomial form of 

 nomenclature iu the body of his work, but adopted it in 

 his explanation of the plates. 



Species 14. (Fig. a, b, Mus. Cuming.) 



Makginella rosea. Marg. testa coHlco-oblongd,pallidi 

 rosed vet cinered, lineis brevibus nigricantibus, ad latus 

 albo-macttlaiis sparsim lentiginosd, spird subobtusd, 

 anfractibus superne tumido-angulatis, labro viodici in- 

 erassato, fusco-nigricante sparsim punclato ; aperturd 

 subpatuld. 



The rose Marginella. Shell conically oblong, pale- 

 rose or ash-coloiu-, sparsely freckled with short black 

 lines, blotched with white at the side, spire rather 

 obtuse, whorls tumidly angled round the upper part, 

 lip moderately thickened, sparingly dotted with fus- 

 cons-blank ; aperture rather open.

Rub. Senegal, West Africa. Cape of Good Hope and 

 Natal, South Africa ; Krauss. 



The rose-colouring of this species is always very deli- 

 cate, and often partakes largely of a dull yellowish-ash 

 tone.
