This South African species differs from M. roxtafa in form, the aperture 

 being shorter and broader, also in the six or seven ribs being more regularly 

 continuous up the spire, and especially in the much stronger spiral striation. 

 The striae are close-set, hair-like, continued on and between the costae, and 

 are easily observable under a simple lens The colour is somewhat variable. 

 Some specimens are white with a broad band round the middle of the body- 

 whorl. Others are light brownish, and with or without a darker peripheral 

 zone. 



Aneilla albozonata, n. sp. 



PI. ii, fig. 9. 



Testa oblonga, supra acuminata, fusca, ad apicem alba, infra suturam et infra 

 medium anfractus ultimi et circa basim albozonata ; spira convexe acuminata, 

 callo tenui induta ; apertura elongata, longit. totius circiter y,, aequans, intus 

 fusca, antice infra columellam alba ; labrum tenue, parum arcuatum, supra 

 ad insertionem album, antice ad extremitatem zonae externae albo tinctum ; 

 columella antice quasi refiexa, oblique sulcata, fuscescens. 



Longit. 20 millim., diam., 10 ; apertura 14 longa, 4.5 lata. 



The coloration of this species is characteristic and constant. The top 

 of the spire is white, a white band falls round the upper part or shoulder of 

 the body-whorl, a narrower white zone accompanies the upper of the two 

 oblique grooves across the knver part of the whorl, the base of which is also 

 white. The surface is smooth, exhibiting only faint lines of growth. 



Smaller than A ciniiaiiiomea, Lamk., from the Red Sea, and differently 

 coloured. It is the cinnaviomea of Sowerby's " Marine Shells of S. Africa," 

 p. 16. 



Aneilla reevei, n. sp. 



PI. ii, fig. 10. 



Testa elongato-ovata, pallide carnicolor, infra suturam pallidior, laevis ; spira 

 plus minus callo pallido induta ; anfractus 5 ?, ultimus magnus, elongatus, 

 convexiusculus, antice oblique bisulcatus, cingulo inter sulcos fusco maculato; 

 labrum pallidum, parum arcuatum ; columella antice incrassata, quasi refiexa, 

 oblique sulcata, alba, vel dilute rosea. 



Longit. 22 millim., diam. 10; apertura 12.5 millim. longa, 4.5 lata. 



The colour is a pale fleshy tint, with a whitish or brownish zone beneath 

 the suture, sometimes with a series of brown spots or dots upon the lower 

 edge of it. The oblique girdle upon the front part of the body-whorl is also 

 generally spotted with red. The reflexed columella is margined on the left 

 side with an excavation or groove.
