318 Messrs, J. C. Melvill and J. H. Ponsonby on 
mamillati, obtusissimi, ceteris tumidis, anfractu ultimo curto ; 
apertura ovata; peristomate tenui, paullulum effuso, margine 
columellari crassiusculo, albo, versus basin truncatulo. 
Long. 17, lat. 4:50 mm. 
Hab. Caledon, Cape Colony (2. WZ. Lightfoot). 
A Subulina of unusual form, perhaps not quiteadult. The 
tumid whorls, extremely obtuse apex, want of sculpture, 
peculiar olive-green hue, and somewhat compressed body- 
whorl amply characterize it. 
By the desire of Mr. Lightfoot, of the South-African 
Museum, Cape Town, who himself forwarded us the speci- 
mens for description, we have named it after Mr. Purcell, the 
discoverer. 
Subulina strigilis, sp.n. (Pl. IL. fig. 7.) 
S. testa minuta, rimata, pergracili, attenuato-fusiformi, crystallina, 
electrino-straminea ; anfractibus 8, quorum apicalis fere immersus, 
obtusus, ceteris delicate et arctissime oblique-striatis, ultimo 
elongato ; apertura anguste ovata; peristomate tenui, margine 
columellari reflexo. 
Long. 7°25, lat. 2 mm. (sp. max.). 
Hab. Karkloof Bush, near Pietermaritzburg, Natal (J. 
McBean). 
A beautifully striate species, of which we have seen four 
examples, slightly varying in size, but in all other respects 
uniformly alike. 
HYPouysia *, gen. nov. 
Testa gracilis, fusiformis, attenuata, sicut in Subulina, sed apud

evoluto. 
Hypolysia Florentie, sp.n. (Pl. Il. fig. 8.) 
H. testa eleganter attenuata, tenui, delicata, albo-crystallina; an- 
fractibus 9-10, quorum apicales duo mamillati, obtusi, ceteris 
apud suturas incrassatis, tumidis, sub lente longitudinaliter 
oblique-striatulis, anfractu ultimo quatuor proximos longitudine 
exsuperante; apertura parva, oblonga; peristomate tenui, supra 
evoluto; columella recta, versus basin truncata. 
Long. 11°50, lat. 2°50 mm.
