494 Mr. W. H. Benson on new Species of Helix and 
vexo; apertura late securiformi-lunulata; peristomate tenui, acuto ; 
margine columellari expansiusculo. 
Diam. major 5, minor 4, axis 3 mill. 
Habitat prope Cape Point. 
This shell was discovered by Mr. George Wing Browning, 
magistrate at Simonstown, a zealous collector in natural history. 
I examined two specimens in the collection of Mr. J. Sydney 
Hawkins, by whom they were brought from the Cape. The 
species is smaller than H. Prionacis, with the same number of 
whorls; the plication is closer, less deep, and more regular, and 
extends only just below the angulate periphery, instead of to the 
umbilicus, which is wider in H. Prionacis. In the latter species 
the periphery is more compressed, the rufous-brown markings 
are more disposed to be spotted than strigate, and do not extend 
to the lower side as in H. Browningi1. 
7. Helix Omphalion, B., n. sp. 
H. testa umbilicata, subgloboso-depressa, superne confertim oblique 
plicata, subtus striatal lucida, polita, viridescenti-cornea ; spira 
subconvexa, sutura subprofunda, apice obtuso; anfractibus 33, 
convexis, ultimo rotundato; apertura obliqua, robundato-dnuata s 
peristomate tenui, acuto ; margine columellari verticaliter descen- 
dente, late reflexo ; umbilico angusto, profundo. 
Diam. major 43, minor 4, axis 2} mill. 
Habitat prope Simonstown. Teste J. S. Hawkins. 
A more minute, darkly coloured species, and with a narrower 
umbilicus, than H. dumeticola, B., which I took in the same 
neighbourhood, and more nearly approaching to, but quite dis- 
tinct from, the large Natal form H. vernicosa, Krauss. 
An immature specimen of Pfeiffer’s fine typical Helix Schirfie, 
from Bredasbosch, figured in pl. 2. figs. 2 & 3 ‘ Malak. Blatter’ 
for 1861, was received from Mr. E. Layard. It occurred at 
Oudebosch, near Gnadendal, in the same quarter whence Dr. 
Pfeiffer’s specimens were procured. Mr. Layard also sent a 
smaller whitish variety from Swellendam, and another variety 
(white, with chestnut bands) from Bredasdorp, to the north- 
east of Cape Lagulhas. Mr. Layard reports that the eyes of 
those varieties are situated at the upper and inner side of a 
lengthened knob turning down from the summits of the upper 
tentacula. The foot, when the animal is withdrawn into the 
shell, looks like a piece of raw meat; and the animal greedily 
devours other living Mollusca confined with it, but in the bush 
is attracted in numbers by pieces of water-melons placed as a 
bait. He also sent a single imperfect specimen of H. Hartvigiana, 
Pfr., received from Oudebosch, and a Jarge variety of H. br- 
sculpta, B., 11 mill. in diameter, which occurs at Bredasdorp.
