cult, however, to always discriminate them. We have seen 
a good many specimens of this, which is probably one of the 
commonest of the genus in its locality, and they are all uni- 
formly conspicuous for the red turgid character of the suture 
at the periphery. 
Yar. /3. meridionalis , var. nov. 
F. testa pulcherrime hyalina, tenuissima, pallide straminea, lasvi ; 
spira convexa ; anfractibus laevibus, rotundis, nitidis ; apertura 
ovata. 
Long. 10, lat. 12 mill. 
Hah . Port Elizabeth. 
From the first var. ( rufofilosa ) this form differs in its 
smaller size, more glossy texture, greater smoothness of 
whorls, and entire absence of the red margined suture. It is 
likewise much flatter. 
Var. 7 . aloicola, var. nov. 
F. testa depresse subovata, olivaceo-cornea, parum nitente ; spira 
convexa, planulata ; anfractibus subro tun datis, laeviusculis ; aper- 
tura lunari-ovata. 
Long. 12, lat. 16 mill. 
Hah . Port Elizabeth (frequens !). 
Thisdiffers from the two preceding in beingof more depressed 
and flattened growth and olivaceous horny texture ; it is also 
a coarser-moulded shell. It is known amongst Port- Elizabeth 
collectors as the Aloe snail, since it feeds on the Liliaceous 
plants ( Aloe , Haworthia } &c.) which so abound on the arid 
rocky plains around. 
We are by no means sure that these three all belong 
to F Huttonice (Bens.), and would invite the attention of 
collectors to these puzzling forms, in the hope that especial 
regard may be paid to the animal. 
We should at present place the South-African species of 
Vitrina (including Helicarion) in the following order : — 
F cingulata, sp. nov. Algoa Bay. 
F. natalensis (Krauss). Natal. 
F. zonamydra, sp. nov. Algoa Bay. 
F. Pceppigii (Menke). Natal. 
F transvaalensis (Craven). Transvaal. 
F. Vandenhrockii (Craven). Transvaal.
