ORTMANN: NAIADES OF THE GREEN RIVER DRAINAGE. 181 
This apparently is a local type of Green River, developed out of 
the lienosa-stock, corresponding to a degree to the vanuxemensis- 
type of the Cumberlandian fauna, without being directly connected 
with it. 
55. Ligumia subrostrata (Say). 
Given by Price as Lampsilis subrostratus. This may be present in 
the lower part of Green River. 
*56. Ligumia recta latissima (Rafinesque): Mm; R; C; B. 
Given also by Price as Lampsilis rectus Lamarck. It is present, but 
is not abundant. 
57. Lampsilis anodontoides (Lea). 
Given by Price from Green and Barren Rivers, but I have not seen 
the true anodontoides, while I found the var. fallaciosa. The form of 
sand- and gravel-bottom in flowing water should, however, be ex- 
pected here. 
*58. Lampsilis anodontoides fallaciosa (Smith): R; B. 
Walker reports this from Rio, and I have found a single individual, 
a male, at Bowling Green, in mud close to the bank in quiet water 
above the riffles. 
*59. Lampsiis siliquoidea (Barnes): Mm; R; C; D. 
Also from Bowling Green.® Price cites this species as L. luteolus 
Lamarck. It generally prefers smaller streams. 
*60. Lampsilis ovata (Say): Mm; O; R; B. 
Also given by Price. It is not rare at the stations mentioned, but 
disappears in the upstream direction. 
*o1. Lampsilis ovata ventricosa (Barnes); Mm; O7 Ri GD aibaoe 
ae 
Also reported by Price as L. ventricosus from ‘‘Barren River,’’ and 
it is in the Walker collection from the lower Green River, Livermore, 
6 A fine specimen donated by Walker originally was labeled: ‘‘Cumberland 
River, Bowling Green, Ky.,’’ but Bowling Green is not on the Cumberland, and 
this species is not found in the Cumberland drainage. Walker lists it from Bowling 
Green.
