10 THE NAUTILUS. 



provisionally keeping beddomei as a subspecies, thinking that the 

 Seychelles type (as it was supposed to he) dussumieri might, when 

 examined anatomically, show some distinctive characters. But 

 since dussitmieri is from Mahe, India, it is doubtless the same as 

 beddomei, which must sink as a synonym. For a general discussion 

 of the synonymy of Mariaella see Ann. & Mag. of Nat. Hist., Jan., 

 1891, pp. 103-104. - 



The removal of Mariaella from the Seychelles fauna gets rid of an 

 apparent anomaly in geographical distribution. 



While on the subject of Oriental slugs I may as well refer to cer- 

 tain section-names proposed in the plural in the paper just cited, and 

 again published in the Check-List of Slugs (1893). I did not 

 change them to the singular number, because I thought that might be 

 left to special students of Oriental slugs ; but as no one has taken 

 the matter up, the changes are made herewith : 



Ibycus, sect. Cnjptibycus (Cryptibyci, Ckll.,1891) type /. magnifi- 

 CMS, Nev. & G.-A. 



Amtenia, sect. Euaustenia (Euaustenice, Ckll., 1891); type A. 

 scutella, Bs. 



Austenia, sect. Cryptaustenia (Cryptaustenice, Ckll., 1891) ; type 

 A. planospira. T. D. A. COCKERELL, March 21, 1898.

NOTICE OF SOME NEW OR INTERESTING SPECIES OF SHELLS 

 FROM BRITISH COLUMBIA AND THE ADJACENT REGION, by William 

 Healey Dall (Nat. Hist. Soc. B. C., Bull. No. 2, 1897. 18 pp., 2 

 plates). While based largely upon material collected by Dr. C. F. 

 Newcombe, Rev. Geo. W. Taylor, Mr. Whiteaves, and other Canadian 

 naturalists, material from Alaskan waters has also been utilized by 

 Dall in preparing this paper. The occidental species of Crenella 

 and Modiolzria are discussed, (7. columbiana, Leana and japonica, 

 M. Taylori and seminuda being new. Nucula charlottensis, Leda 

 cellullta, conceptionis and leonina are also new or lately described 

 forms. Other new species of bivalves belong to Yoldia, Malletia 

 and Macoma. Two Cadulus, Hepburni and Tolmiei, and species of 

 Cythara, Turbonilla and Odontostomia are described as new. Ris- 

 $oina Newcombei, Molleria quadrce, and Eucosmia htrida are also 

 new ; all being illustrated by very good figures.
