3. Strophitns cdcntnlus (Say) 



4. Obovaria cir cuius lens (Lea) 



5. Lanipsilis luteola (Lam.) 



6. Lanipsilis mulfiradiata (Lea) 



And the Carnegie Museum possesses, from Little Coal River, 

 from the Hartman collection : 



7. Quadrula pustulosa (Lea) 



8. Quadrula metanevra ivardi (Lea) 



9. Pleurobema obliquum coccineum (Conr.) 



This would add 5 forms (nos. 1,4, 5, 8, 9), so that 2y forms are 

 known from the lower Kanawha drainage, which are practically all 

 typical upper Ohio forms. 



Going up the Kanawha, we find that this river, as New River, 

 comes through a canyon out of the mountains. This canyon is ex- 

 tremely rough, containing several falls (Kanawha falls at lower 

 end of canyon, and New Richmond falls, eight miles below Hinton. 

 Good photographs of New River scenery have been published by 

 Campbell and Mendenhall, 1896). In the region of Hinton, Sum- 

 mers Co., W. Va., the river is somewhat less rough. Here I col- 

 lected, at the confluence of Nezi^ River and Greenbrier River, the 

 following species : 



List No. 13. 



1. Quadrula tuber culata (Barn.) 



2. Rotundaria tuber culata (Raf.) 



3. Elliptio dilatatus (Raf.) 



4. Symphynota tappaniana (Lea) 



To these, probably, Alasmidonta marginata (Say) should be 

 added, for it is found farther up in the New River drainage, and 

 thus we would have five species here, four of which are found in 

 the lower Kanawha drainage, while one (Symphynota tappaniana) 

 is entirely new, and found nowhere else in the whole upper Ohio 

 drainage. In fact, this is a species known hitherto only from the 

 Atlantic watershed. 



Farther up I collected in the Greenbrier River at Ronceverte, 

 Greenbrier Co., W. Va. ; in Nezu River at Pearisburg, Giles Co., Va. ;
