NOTES AND QUERIES. 267 
Isle of Wight. I also take this opportunity to correct an error of locality 
made by the late Dr. Gray in the ‘ Catalogue of Batrachia Gradientia,’ and 
which I have unfortunately reproduced in the recent issue of that Catalogue. 
Specimens of M. palmata are mentioned as having been obtained near 
Nottingham by Mr. Higginbottom. But, from the article on British Newts, 
published by the latter gentleman in the ‘ Annals and Magazine’ for 1858, 
it is evident that the specimens presented by him to the British Museum 
were not from Nottingham, his place of residence, but from Bridgewater 
and Scotland, whence he obtained them through Messrs. Baker and Wolley, 
the original discoverers of the species in this country. To the well-known 
peculiarities which distinguish the Palmated Newt from the common species, 
but which apply to the males only, may be added the total absence in the 
former of pigment on the throat, this region being of a transparent flesh- 
colour—a character which affords an excellent criterion for the distinction 
of the two allied species in either sex.—G. A. BouLEne»r (8, Courtfield 
Road, S.W.). 
MOLLUSCA. 
Segmentina lineata, Walker, a Thread-spinner.— My brother 
(L. M. C.), who has been keeping sume of these interesting little Planorbes 
in a bell-jar, informs me that he has observed a specimen spinning a down- 
ward thread from the surface of the water to the bottom of the bell-jar. 
This is to me a very interesting fact, as I believe that this species has 
never before been recorded as a thread-spinner, and as it belongs to a 
different section of Planorbis to those species already known as thread- 
spinners (e. g., P. carinatus, P. spinorbis), it is well worth recording. The 
specimen in question was found in a ditch at Barnes, in company with 
P. nitidus, by my brother (D. B.C.), who, it may be well to remark, 
discovered a specimen of Limnea glabra monst. decollatum in a pond close 
by. This last is a very rare species in the London district.—T. D. A. 
CockERELL (51, Woodstock Road, Bedford Park). 
Swiss Mollusca.—The following is a list of an interesting collection of 
land-shells made by Mr. G. F. Payn in the neighbourhood of Weggis 
during the last week of July, 1884 :—Clausilia parvula (abundant), C. lami- 
nata, Cochlicopa lubrica var. lubricoides, Pupa secale (common), Helia 
pomatia, H. pulchella var. costata, H. lapicida, H. rotundata, H. personata 
(several), H. obvoluta, H. incarnata, Succinea oblonga, Hyalina erystallina, 
H. nitidula var. nitens (= Helix nitens, Michaud), and Pomatias septem- 
spirale. Mr. Payn sent me some of the P. septemspirale alive, aud I had 
an opportunity of examining the animal. It is very curious, light in colour, 
with a long snout, something like Cyclostoma elegans. The operculum is 
thin and light in colour.—T. D. A. CockerELL (51, Woodstock Road, 
Bedford Park).
