THE NAUTILUS. 131 



the report of theConchological 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 

 Planorbis ncmtileus 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. 

 /mid Hi 'us. 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. HANHAM, Winnipeg,

 CESSE- ALICE, 1888-1895, par Ph. Dautzenberget H. Fischer (Mem. 

 Soc. Zool. France, 1886, pp. 104, pi. 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 sigsbeei, centimata, serga, 

 comatropi* Dall, chariessa Watson, Sip ho profundicola Verrill and 

 Smith, Coralliophila lactuca Dall, etc. Among the more interesting ' 

 new species described are two Mitromorphas, Kryptos elegans Jetfr. 

 mss., Iphitus cancellatu* and tenerrimus, Danilia affinis, some fine 

 species of Solariella and Calliostoma, a Turcicitla, two Fissuriseptas, 

 two species of Propilidum and an Acmtea (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-
