THE NAUTILUS. 131 
the report of the Conchological Division of the Biological Section of 
the Hamilton Association contained in the Journal and Proceedings 
of the Association for the Session 1889-90, the following note on 
Planor bis nautileus appears :— 
Occurs in a small piece of marsh at the junction of Hamilton Bay 
(Lake Ontario) and the Desjardines Canal. A very tiny shell, the 
smallest water shell known to me; is hairy. The Rev. G. W. Tay- 
lor in naming it states that this is identical with the English P. 
nautileus. From its small size is difficult to find ; if an introduced 
shell it would be interesting to know by what agency it reached its 
present habitat. Do not know that it has been taken anywhere else 
in North America. I found the shell among layers of dead leaves 
and on the stems of reeds in a few inches of water; not many were 
met with, but as it required considerable patience, especially in such 
moist surroundings, special search for them was only made on one 
or two occasions. The Dundes marsh is of large area, and I dare 
say the species occurs throughout it—A. W. Hannan, Winnipeg,

CESSE-ALICE, 1888-1895, par Ph. Dautzenberg et H. Fischer (Mém. 
Soe. Zool. France, 1886, pp. 104, pl. 7). An important paper on 
the deep sea Gastropod fauna of the Eastern Atlantic, supple- 
menting the extensive works of Jeffreys and Watson. Most of 
the dredging was done around the Azores Islands, where be- 
sides numerous new species of many genera, a considerable num- 
ber of forms first described from the western Atlantic and Gulf of 
Mexico occurred, such as Pleurotoma sigsbeet, centimata, serga, 
comatropis Dall, chariessa Watson, Sitpho profundicola Verrill and 
Smith, Coralliophila lactuca Dall, ete. Among the more interesting 
new species described are two Mitromorphas, Kryptos elegans Jeffr. 
mss., [phitus cancellatus and tenerrimus, Danilia affinis, some fine 
species of Solariella and Calliostoma, a Turcicula, two Fissuriseptas, 
two species of Propilidum and an Aemea (Azores, 1,385 meters!) ; 
the latter probably not really belonging to this genus. 
The figures are for the most part very good examples of heliotype 
work, but in some cases lack clearness of detail. Messrs. Dautzen-
