120 THE NAUTILUS. 



Animaux sans vertelres annotated by Lamarck himself. I supposed 

 that this neat mounting was done by Chenu, but the present custo- 

 dians did not know. The director and his assistants pay great regard 

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

 part of a memoir illustrating by photography the shells of Lamarck 

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

 be issued this year, and will include the bivalves. 



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

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

 of Bourguignat, who left it here." 



BANDED POLYGYRA MOBILIANA : Some months ago I received 

 from Herbert H. Smith a few Polygyra mobiliana Lea from near 

 Mobile, Ala. Most 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 remaining and found that the 

 majority of them were banded. Since then Mr. L. H. McNeill of 

 Mobile has collected numerous specimens and finds most of them 

 banded. I have just received 17 specimens from him of which 15 

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

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

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

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

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

 " sweeping " the grass at night with an insect net. GEO. H. CLAPP. 



MUREX 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. H. Holmes in the Gulf of 

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



PSEUDOGALBA, NEW NAME FOR SiMPSONiA. Mr. Bryant 

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

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

 as Chamberlaina duclerci. The name Pseudogalba may be used in 

 place of Simpsonia (Lymnseida3 of Nortli and Middle America, page 

 23G). It is perhaps expressive of the relationship of the group to 

 Galba FRANK C. BAKER.
