than carinata gibba. It must, therefore, be held to be uniden- 
tifiable. 
Then follows U. fasciola Raf. According to Vanatta, the 
Poulson type belongs to luteola auct. (= siliquoidea Bar.), 
but this is contradicted by Conrad, who mentions also a speci- 
men from the Poulson Collection, which is called fasciolus, 
and is identical with multiradiatus Lea. Moreover, as will 
be shown under Lampsilis fasciola, Rafinesque’s description 
does not fit the present species, but does fit multiradiata very 
well. Thus, also, this name cannot be used. 
Next are two names given by Barnes, ’23, inflatus and sili- 
quoideus. That these are identical and belong here has been 
recognized by Lea, ’29, confirmed by Conrad, and accepted by 
Simpson, and there is no doubt that siliqguoideus is the male, 
imflatus the female. Of these two names, siliqguoideus has been 
selected by Lea in ’29, while Conrad, in °34, selected inflatus, 
but changed subsequently (’36) to siliquwoideus. The latter 
thus is the valid name, and should be used for the species 
hitherto commonly called Jiuteola.
