PSEUDANODONTA ELONGATA (?) IN YORKS. 
J. A. HARGREAVES anp J. DIGBY BURGH pees s. 
On January 29th, 1916, Mr. J. Digby Firth obtained from 
Wakefield a number of freshwater bivalves of various kinds, 
including Unio pictorum, U.tumidus, Anodonta anatina, etc., 
Among the Anodons were two living specimens, which Mr. 
Hargreaves considered to belong to the genus Pseudanodonta 
Bourg., of which two species have been added to the British 

Pseudanodonta elongata (?). 
list during the last few years. The specimens were submitted 
to Mr. J. W. Taylor, M.Sc., who confirmed the generic deter- 
mination. 
Of the two known British species, Eco anowonta elongata 
Holandre, is recorded from the Thames, and P. rothomagensis 
Locard, from the River Teme in Worcestershire. Both are 
recorded in the Journal of Conchology for January IgII, and 
January IgI2. 

* The specimen shown on the left of the figure has been kindly given 
to the Municipal Museum at Hull by Mr. Digby Firth, and can be seen 
at any time by those interested,—Ep.
