182 ANNALS OF THE CARNEGIE MUSEUM. 
McLean Co., Ky. At the lower stations it is found associated and 
intergrading with typical ovata, but at the upper stations it is not 
accompanied by the latter. 
*62. Lampsilis fasciola Rafinesque: O; C; B. 
Recorded by Price as L. multiradiatus Lea. Present in the Walker 
collection from Bowling Green. Not rare at the two places where 
I found it. 
*63. Dysnomia triquetra (Rafinesque): O; R; G; C; D; B. 
Listed by Price as Truncilla triquetra. Not abundant, but ap- 
parently well distributed over the system. 
64. Dysnomia torulosa (Rafinesque). 
Given by Price as Truncilla perplexa Lea. It would be quite im- 
portant to have this record verified, for exact localities for this species 
are very few. They belong to the lower Ohio, Tennessee, and Cumber- 
land.? The presence of the var. gubernaculum in the Green River 
drainage also points to the probability that the typical form of 
torulosa exists here. 
*65. Dysnomia torulosa gubernaculum (Reeve): Mm; C; B. 
In the Walker collection it is represented from Green River, Greens- 
burg, Green Co. 
This apparently is the Truncilia perplexa rangiana Lea of Price. 
The best set (6 o'o’, 4 @ @) is that collected by Clench at Camp- 
bellsville. I found only a dead female at Mammoth Cave and a 
living male at Bowling Green. The females have the marsupial ex- 
pansion tinted dark green, and thus this is gubernaculum. 
This is the headwaters-form of torulosa, known hitherto only from 
the upper Tennessee, but it is not astonishing that the typical torulosa 
(an Ohio-type) has developed this form in Green River. 
71 have not been able to find any published record for this species from the 
Cumberland, and have commented upon this (Ortmann, 1924, p. 45 and 1925, 
p. 363). Yet Walker has informed me that he has specimens of torulosa from the 
Cumberland. According to the labels they have gone through the hands of Wetherby 
and Marsh, and probably were collected at Nashville by Dr. Lindsey in 1877. 
This seems to establish the presence of torulosa in the Cumberland River, although 
the information is subject to doubt, and it is remarkable that this species never 
again has been found in the Cumberland.
