Autonoe riparia and Stenogyra coronata have been with- 
drawn from the fauna of Trinidad by Mr. Guppy, and his Pupa 
auriformis he considers a probable variety or ‘‘accidental form” 
of P. uvulifera, The Autonvse is said to be synonymous with 
Auricula pellucens of Menke, and the Stenogyra was founded 
upon a single example. Not having specimens of either of these 
or of the Pupa, I cannot offer any suggestions with regard to 
their identification.

Note on Helix hortensis near Dover.—On April 17th, I found 
Hf. hortensts well out and active in a shrubby chalk wayside bank near 
Dover, the day being warm and mild. They were mostly about three or 
four feet up the shrubs. Chief variations 00045,-00005, 10045, 10305, 
0(23)(45), and 12045. Also alba, the presence of which in a locality seems 
to me to lead to variations with few bands; A. caztzana and H. rufescens 
the only other active shells. In another direction I found A. xemoralis 
swarming up the beech trees; 7. arbustorum also active. These two had 
made two-thirds of their second year’s shell already ; &. /aficzda also active. 
I found &@. ¢ervrestris at home, but not as yet active, in its only British 
habitat. A. aspersa, L/. virgata, and A. caperata still hybernating.—J. W. 
Horsey, St. Peter’s Rectory, Walworth. (ead before the Conchological 
Society, May 13th, 1896). 
Limax marginatus-Mill.=L. arborum B.Ch. in Northampton- 
shire.—On May 3rd, in Rockingham Park, I found several examples of 
the ‘tree slug,’ which is a new species to this county. Rockingham Park has 
only recently been thrown open to members of the Northants Natural 
History Society, and may yet yield other species.—LIONEL FE. Anpams, 
Northampton. (Mead before the Conchological Soctety, May 13th, 1806). 
Helix fusca and Azeca tridens in Denbighshire.—In the carly 
part of April, 1896, I paid a visit to the Cefn Caves in the carboniferous 
limestone of the Elwy Valley near St. Asaph. The time at my disposal for 
shell-collecting was limited to an hour, but, judging from the number of 
species obtained in that time, the hanging woods in the neighbourhood of 
the caves would well repay a thorough and systematic search. In addition 
to Helix fusca and Azeca tridens, of each of which I collected several ex- 
amples, the following species, among others, were noted:—A7zon minimus, 
A. circumscriptus, Vitrina pellucida, Hyalinia glabra, H. pura, and v. 
netidosa, H. crystallina, H. fulva, Helix rotundata v. pyramidalis, H. 
rupestris, H. pygmea, H. aculeata, H. pulchella v. costata, H. arbus- 
torum, H. sranulata, Bulimus obscurius, Vertigo edentula, Clausiha lamin- 
ata, and Carychium mintmun.—CHAS, OLDHAM, Romiley. (Read before 
the Conchological Society, May 13th, 1896).
