A species collected in Arctic America by the “ Vega.” I-am indebted to Mr. 
Dall for a specimen from Commander Island, Siberia. 
Jaw arched, smooth, with median projection. Lingual membrane with about 
42-1-42 teeth. Centrals tricuspid: laterals bicuspid, twelve in number on 
each side: marginals about thirty in number on both sides, aculeate, simple, 
without bifurcation or side spur. Fig. 516 of Man. Amer. Land Shells shows 
a central tooth with its adjacent lateral and three extreme marginals of Mr. 
Dall’s specimen. 
From Seattle, Washington Territory, I have received a small Limaz similar 
in outward appearance to hyperboreus, and with similar dentition.

Prophysaon Hemphilli, Bu. & Bryn. 
Prophysaon Andersoni, J. G. C. 
It is a true Prophysaon, though described originally as an Arion. 
The lingual membrane has 30-1-30 teeth, with about 12 perfect laterals. 
Centrals tricuspid : laterals bicuspid : marginals with one long, stout, oblique 
inner cutting point, and one outer, short, blunt, sometimes bifid cutting point. 
Resembling that of P. Hemphilli. 
Jaw low, arcuate, ends blunt; with numerous (over 15) irregularly devel- 
oped, broad, stout ribs, denticulating either margin. 
Animal small, long, and slender, dirty white with dark reticulations: an in- 
distinct dark-colored circle around the mantle near its edge, and a dark band 
running longitudinally from the rear of the mantle to the tail on each side of 
the centre of the back. 
Reticulations foliated as in Prophysaon Hemphilli and in the figure of Arion 
foliolatus. The mantle covered with minute tubercles, not foliated.
