120 THE NAUTILUS. 



Animaux sans vertehres annotated by Laniarck himself. I supposed 

 that this neat mounting was done by Chtnu, but tlie present custo- 

 dians did not know. Tiie director and iiis assistants pay great regard 

 to this collection but they have not a conciiologist on the staff. One 

 part of a memoir illustrating by photography the siiells of Lamarck 

 has already appeared. I saw proof of the next part which should 

 be issued this year, and will include the bivalves. 



" Ttiis Museum has also the complete collections of Brot, the 

 specialist on Mehtnia, who was a Geneva citizen. Also the collection 

 of Bourguignat, who left it here." 



Banded Poi.YGYnA mobiliana : Some months ago I received 

 from Herbert H. Smilii a few Polygyra mohiliana Lea iVom near 

 Mobile, Ala. IMost of the shells were immature but I noticed that 

 three adults were distinctly banded and some of the young also 

 showed a faint band. On bringing the matter to Mr. Smith's atten- 

 tion he examined all that he had jemaining and found that the 

 majority of them were banded. Since tiien Mr. L. IL McNeill of 

 Mobile has collected numerous specin)ens and finds most of them 

 banded. I iiave just received 17 specimens from him of v/hich 15 

 are banded. The band is brown, much darker tiian the balance of 

 the shell, and is located just above the periphery. Shells collected 

 at Foley, Baldwin Co., are bandless and Smith says tiiat he has seen 

 no baniled shells of this species except those collected near Mobile. 

 Mr. McNeill informs me that he got a great many of this species by 

 " sweeping " the grass at night with an insect net. — Geo. H. Clapp. 



MunEX FULVESCENS Sowerby : Some handsome specimens of 

 this species, pure white in color and measuring about seven inches in 

 length, were recently obtained by Mr. J. IL Holmes in the Gulf of 

 Mexico, off Wakulla Co., Fla., at a depth of 125 feet — C. W. J. 



PSEUDOGALBA, NEW NAME FOR SlMPSONIA. — Mr. Bryant 



Walker has called my attention to the name Simpsonia, which is 

 preoccupied by Rochebrune (1905), for the Naiad previously known 

 as Chamherluiaa duchrci. The name Pseudogalba may be used in 

 place of Siinpsonia (Lymnoeida; of North and Middle America, page 

 230). It is perhaps expressive of the relationship of the group to 

 Galba. — Frank C. Baker.
