Linnean, though frequently expressed in one, two, or three words, on 

 page 4, line 3 from the bottom, we find the words " Glycemeris Cha^na 

 Aldrovandi,''^ with a reference to plate 414. Turning to plate 414 we 

 find it to represent the first species of Lister's group of Chamse, under 

 which it is also indexed on the same page above cited. The 

 engraving is lettered: "Sectio 10, cap. I de ChatncB, ab altero tanhim 

 latere fer} natwaliter Hiatitibus , Cha?na Glycimeris Aldrova?ide, Mare 

 hispanie tnediter,^'' 



It seems then, that, so far, from the word Glycemeris being used in 

 this instance in the sense of a Linnean genus, it is really used in a 

 specific sense, as a species Glycemeris of the group Chamce, to which 

 it had been referred by Aldrovandus. Tiiis being the case, the first 

 use of Glycymeris for a genus in the Linnean sense becomes that of 

 Da Costa in 1778, as I have elsewhere shown in extenso. 



New Records for West Lancashire. — One morning, early last month, Mr. 

 J. W. Jackson and I left Silverdale station and struck a footpath across the lime- 

 stone fells leading to the church. We soon reached a favourite hunting-ground ; 

 the little hollow known as Bank Well, where a search was at once made for Veriigo 

 pygmaa, obtainable here in fine condition. Working at the base of a low limestone 

 cliff, and almost at the roadside, I was surprised to find in the soil Cacilioides 

 adcitla, and a combined search soon yielded nearly a score of specimens. Besides 

 occurring in the moss and earth at the base of the cliff, several were found in the 

 earth-filled crevices in the cliff-face. They had evidently been washed down from 

 above, as after heavy rain the water drains through at this point and collects in the 

 tarn just below. Comparison should be made with the Miller's Dale habitat for 

 this shell, i.e., the "over-grown talus at the foot of a series of carb. limestone cliffs" 

 (J. Co7ich., vol. 10, p. 303, 1903). A further search of the immediate locality was 

 entered on in the hope of getting living specimens, but instead Helicella itala was 

 found to be in possession of the grassy slopes, and as a new record, was duly 

 "boxed." Leaving this spot, much elated, we regained the Arnside road. On the 

 top of a mossy wall, covered in parts with ivy (a typical habitat), Mr. Jackson 

 found what we had long been in search of — Vertigo alpestris. Only three living 

 examples were taken, with several dead ones, but this scarcity may be attributed to 

 the lateness of the season. It was found in company with V. pusilla. Vertigo 

 alpestris has been recorded for South Lancashire by Dr. Gilbertson, who found it 

 at Clitheroe (Jeffreys, " Brit. Conch.," vol i, p. 260), but the most strenuous efforts 

 on the part of later conchologists have failed to corroborate this. A later record is 

 that of Roughlee Valley, Pendle Forest {J. Conch., vol. 9, p. 221, 1899). Refer- 

 ence should also be made to the records for Grange-over-Sands and Cark {J. Conch., 

 vol. II, p. 44, 46), which districts, although included in Vice-County 69, have per- 

 haps a more direct geological bearing on the above than Clitheroe. — J. Davy Dean
