On the Species of Ve^ieridce found in Japati. By Arthur 

 Adams. 



Dosinia gibba, A. Ad. 



I do not believe that G-emma gemma, Totten, is found in Ja- 

 pan. Mr. Adams hiis probably mistaken an undescribed allied 

 species for it. 



Nudibranchs in Fresh Water. By J. E. Gray. 



Mr. Kent described, at the last meeting of the Zoological So- 

 ciety, a new Nudibranch under the name of JEmbletonia Grayii, 

 discovered in the Victoria Docks at Rotherhithe. When I men- 

 tioned the circumstance to Dr. Mobius, at Kiel, he observed : 



"It was very interesting to me to find that a mollusk of the 

 family ^olididce had been discovered in brackish water near 

 London Bridge. In the Baltic Sea, Emhletonia ijallida extends 

 as far as East Prussia, near Konigsberg, where the water has 

 only 7 of salt in 1000. In like manner, Brotolimax capitatus 

 {= Limapontia nigra) endures almost fresh water at Bornholm 

 and Gothland, in the Baltic." 



Mr. Kent informs me that Embletonia G-rayii is nearly allied 

 to E. pallida, and it has been found in company with Daphnia, 

 Floscularia, and many other fresh water Entomostraca and 

 Rotifera.
