tions to the British Fauna, for which he deserves the warmest 

 support and encouragement of zoologists. About three 

 months ago I received from him a tube containing speci- 

 mens of an Entomostracon which he was unable to identify, 

 rightly considering it new to this country. The form proved 

 to be the beautiful Leptodora hyalina of Lilljeborg. A few 

 days later another tube was sent by him, containing a 

 species which I identified as the HyalodapJmia Kahlber- 

 gensis of Schodler. These two very fine Entomostraca were 

 obtained by Mr. Bolton from a deep reservoir at Olton. 

 Besides these I have to thank Mr. Bolton for the new Pro- 

 tozoon Lithamoeha discus^ described in the present number 

 of the Journal. Last autumn, from the same source, I 

 received an abundant supply of one of those very interesting 

 spiculate Heliozoa, which my colleague, Mr. Archer, of 

 Dublin, was the first to make known to zoologists. The 

 specimens forwarded by Mr. Bolton proved to be the Raphi- 

 diophrys pallida, a species named by Prof. F. Eilhard 

 Schulze, and assigned by him to Archer's genus. 



Mr. Bolton has also during the year supplied me with 

 the finest specimens of Hydra fusca which I have seen, 

 with Volvox, Uroglena, and other similar forms. A few 

 marine organisms have been distributed by him, namely, 

 the interesting disc-like larvae of the Polyzoon Alcyomdium, 

 and the delicate polyp Lucernaria auricula. — E. Ray
