''P. tesia ovali, pallida, fjilvo-inaculosa, spiraliier I eviter striata; spira 

 proditcta, ad suttirain profnude ca/uiliciilata, anfractilnis ad siititram 

 angulatim elevatis ; apertura ovata, ajitice vix eiiiargijiata. 

 Till recently, this species was considered a link between Macron 

 and the typical Latrunculi {Eburnce). But Mr. Charles Hedley 

 having, in 1899, examined the anatomical details, is inclined to pro- 

 pose its transference to the Struthiolarid;^.^ The operculum appears 

 buccinoid, but the shell itself possesses the revolving spiral canalicu- 

 lation near the base of the last whorl, ending in a tooth-like projection 

 on the outer lip, this being unlike the Latrunculi, though resembling 

 many Ancilke, and of course, Macron and Pseiidoliva. The surface 

 is also closely spirally sulculose throughout, while the chestnut 

 blotches and maculations are, after all, not of the same character in 

 the Latrunculi, and, undoubtedly, Zeinira will stand as a monotypic 

 genus on its own merits. Native of Australian seas.

We would repeat, in conclusion, that any arrangement of the 

 Pseudolivce is as yet, merely tentative and artificial, and will continue 

 to be so till the whole have been studied anatomically. 



Turricola terrestris and Helix virgata. — I visited al the beginninir of Sep- 

 tember the unique British habitat of Turricola terrestris and found (l), that it is 

 undoubtedly spreading its borders ; (2), that it was so numerous, that as a test I 

 stood with one foot on the road and another on the chalky bank, and without mov- 

 ing a foot I gathered sixty-two specimens, which I relumed ; (3), that it found 

 congenial food in bits of paper on the wayside, eating holes therein as heartily as 

 did Helix lucasi when in my study ; (4), that where it had strayed on to a clover- 

 field it had grown considerably in size and in altitude ; (5), that I could see none 

 in two places where I had tried to establish a colony. It may have been that I fell 

 into what is, I believe, a common mistake, namely, to transplant only adult speci- 

 mens that will not again produce eggs. This year I have experimented with imma- 

 ture specimens in another place, and will report next year with what effect. Helix 

 virgata var. radiala is abundant and fairly fine in Rye. It is, as regards Kent, 

 mainly a Romney Marsh seaside form. I have not found it north of Hythe nor 

 south of Rye. I looked in vain for var. alba in many places, and at last found a 

 colony of finer specimens than usual a few yards from where I was staying. Have 

 any conchologists noticed a dearth of snails this year ? And if so, to what cause do 

 they attribute it ? H. neinoralis was rare in several spots where it used to abound. 

 H. cartusiaiia I could not find on Barham Downs where it used to be in plenty.
