NOTES. 



OPEAS MAURITIANUM (Pfr. ) Subulina octona (Brug.) was 

 reported from green-houses at Philadelphia, Pa. in THE NAUTI- 

 LUS volume vi, p. 107, (1893) and volume xi, p. 120 (1898). 

 Upon examining one of these sets collected by Mr. Robert 

 Walton, I found one specimen of Opeas mauritianum (Pfr.) 

 This is an addition to the " Mollusk Fauna of Philadelphia" 

 published by Mr. Morris Schick in THE NAUTILUS, volume viii, 

 p. 133 (1895). The specimen is in the collection of The Acad- 

 emy of Natural Sciences of Philadelphia, tray No. 113421. 

 We also have Opeas mauritianum in the the collection from a 

 green-house at Garfield Park, Chicago, Illinois, being A. N. S. P. 

 No. 91237, collected by Mr. F. C. Baker in 1906 ; also No. 

 11748 collected at Washington, D. C.. by Mr. E. Lehnert many 

 years ago. E. G. VANATTA. 



WE have learned with deep regret of the death, on the 26th 

 of March, of DR. WILHELM KOBELT, the distinguished German 

 conchologist, at the age of 76. 



1 This species was first defined by Walker, in NAUTILUS vol. 29, p. 53.
