the more probable that Harn’s shells were distinctly from this drain- 
age system. ; 
W. B. Marshall published (Bulletin New York Museum, 1, 1892, 
pp. 3 e¢ seg.) a list of Unionidee from New York. ‘The species were 
‘<from localities within the limits of the state of New York, or from 
the Allegheny River at Warren, Pa., just south of the New York 
boundary.’’ It is much to be regretted that Marshall did not realize 
the importance of indicating the exact localities, since his list covers 
a territory which is of the greatest interest. We do not know which 
species of this list were found in Warren County, Pennsylvania. 
I have myself collected the following species in Warren County 
(Allegheny River, Connewango, and Brokenstraw Creeks) : 
MARSHALL’S LIST. 
Truncilla perplexa rangiana (Lea) = Unio perplexus Lea. 
Micromya fabalis (Lea) = U. fabalis Lea. 
Lampsilis ventricosa (Barnes) = U. occidens Lea and U. ven- 
tricosus Barnes. 
a ventricosa ovata (Say) = U. ovatus Say. 
$e multiradiata (Lea) = U. multiradiatus Lea. 
es luteola (Lamarck ) = U. luteolus Lamarck. 
ci ligamentina (Lamarck) = U. ligamentinus Lamarck. 
cc recta (Lamarck ) =U. rectus Wamarek: 
Ptychobranchus phaseolus( Hildreth) = U. phaseolus Hildreth. 
Strophitus undulatus (Say ) = Anodonta edentula Say and 
pavonia Lea. 
Anodonta grandis Say = Anodonta lewisi Lea. 
Symphynota compressa Lea = U. pressus Lea. 
ca costata (Rafinesque) = Margaritana rugosa Barnes. 
Alasmidonta marginata Say = M. marginata Say. 
Quadrula coccinea (Conrad) (**without evidence that it in- 
habits New York ’’ ). 
We see that all, except the last species, are in Marshall’s list. But 
in addition, the following western species are recorded from New York 
state : 
Unio alatus Say = Proptera alata (Say). 
‘¢ clavus Lamarck = Pleurobema clava (l.amarck). 
Margaritana complanata Barnes = Symphynota complanata (Barnes). 
Unio crassidens Lamarck.
