104. Messrs. J. C. Melvill and J. H. Ponsonby on 
A very handsome addition to Macrocyclis; much of the 
same build as bullacea (Pfr.), but larger and in every way a 
more striking species. 
Three specimens, in magnificent condition. 
The colour olivaceous horny, subpellucid in texture, in form 
effuse and depressed, slightly conical towards the apex ; 
whorls four in number, beautifully closely longitudinally lirate, 
the lire giving a silky appearance to the whorls. Below, the 
last whorl is quite smooth, olive-green, and very shining. The 
umbilicus is narrowly profound, mouth lunar; lip simple, 
thin, slightly reflexed at the columellar margin. 
Discovered by Mr. Quekett, the active Curator of the 
Maritzburg Museum.

Hab. Transvaal (Mr. Bowker). In Coll. Edgar L. Layard, 
Esq. 
This shell, collected by Mr. Layard’s nephew, Mr. Bowker, 
in the ae val is, though in damaged condition, so peculiar, 
that we agree Sih its owner it 1s worthy of ’ description. 
Nothing we have seen in the National or other collections 
exactly corresponds with it, though it does not at first sight 
seem to possess any extraordinary characters excepting in 
being sinistral. 
The shell is thin, pale ochraceous, with longitudinal darker 
brown flames; whorls seven, microscopically eranato-striate 
the strie transverse, the last whorl appearing Bios smooth, 
though the above- entered striations are still with a iene 
traceable for, at all events, some little distance below the 
suture. The whorls are slightly ventricose, lip simple; 
columella slightly contorted, fuscous, and strongly truncate. 
3. Achatina penestes, sp.n. (PI. III. fig. 3.) 
A, testa ovato-pyramidali, supra, et preesertim ad apicem, multum 
attenuata ; anfractibus sex, sub lente granato-decussatis, ad 
suturas impressis, anfractu ultimo rapide accrescente, ad basin 
leviore, longitudinaliter irregulariter ruguloso ; apertura ovato- 
oblonga, columella ad basin contorquente, truncatula. 
Long. (sp. maj.) 1°30, lat. °75 inch. 
Hab. Pretoria (Wotton).
