10 THE NAUTILUS. 
provisionally keeping beddomei as a subspecies, thinking that the 
Seychelles type (as it was supposed to be) dussumieri might, when 
examined anatomically, show some distinctive characters. But 
since dussumieri is from Mahé, India, it is doubtless the same as 
beddomei, which must sink as asynonym. For a general discussion 
of the synonymy of Mariaella see Ann. & Mag. of Nat. Hist., Jan., 
1891, pp. 103-104. 
The removal of Mariaell/a 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 pluralin 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 :— 
Lbycus, sect. Cryptibycus (Cryptibyci, Ckll., 1891) type I. vite 
cus, Nev. & G.-A. 
Austenia, sect. Euaustenia (Euaustenie, Ckll., 1891); type A. 
scutella, Bs. 
Austenia, sect. Cryptaustenia ( Cryptaustenie, Ckll., 1891) ; type 
A. planospira.—T. D. A. CocKERELL, March 21, 1898. 
RECENT PUBLICATIONS. 
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 Modiolaria are discussed, C. columbiana, Leana and japonica, 
M. Taylori and seminuda being uew. Nucula charlottensis, Leda 
cellulita, 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- 
soina Newcombei, Molleria quadre, and Eucosmia lurida are also 
new; all being illustrated by very good figures.
