302 TAYLOR: ON HELIX ARBUSTORUM. 



animal and shell (pi. iv., f. i) of a species which he refers to the 

 E. insignis of Pfeiffer, but which appears to me to represent that 

 above described. The form and sculpture are quite the same, 

 the latter being very much coarser than that of E. insignis. 

 Unfortunately the view given of the shell does not show the 

 umbilical region, and consequently I am in doubt respecting that 

 part. Another character well represented in Martens's figure is 

 the abrupt change of sculpture from coarse lirse to a nearly smooth 

 surface on the front of the body-whorl just above the aperture. 

 This peculiarity is scarcely noticeable in E. insignis. 



I take this opportunity of giving a name to a distinct species 

 which is figured by Martens (I.e., pi. iv., f 4 — 5) as the E. 

 ?nonodon of Morelet. Of this species, which I propose to name 

 E. JDohrni, the British Museum possesses two specimens. It is 

 a larger and more pupiform shell than E. monodon, consisting of 

 fewer whorls and with a shorter and less conical spire. Dr. Dohrn 

 has already pointed out its distinctness in the "Jahrbiicher 

 der Deutschen Malakozoologischen Gesellschaft" for 1878. 



ADDITIONAL NOTES ON HELIX ARBUSTORUM. 



By JOHN W. TAYLOR. 



Since the publication of the "Life History" of this species 

 additional information has come to hand, mainly through the 

 kindly interest of Mrs. Fitzgerald, Rev. J. McMurtrie, M.A., 

 F.L.S., Mr. W. D. Roebuck and other friends. 



Distribution. 



Rev. R. Boog Watson, F.L.S., informs me that according to 

 Nordenskiold and Nylander this species is found in Finland only 

 in Karelen and Aland, where it is the commonest of the large
