Beatricea nodulosa was described from the Ordovician at Wreck 1 
Point, Salmon River, and Battery Cliff, on Anticosti Island. The | 
types appear to have been lost. A specimen from Battery Cliff, I 
preserved in the Museum of the Geological Survey of Canada, 
owes its nodose character to a parasitic growth of Lahechia. Judg- 
ing from the specimens of Beatricea preserved in the Museum of the 
Canadian Survey, the nodes of Beatricea nodulifera are smaller 
and closer together. It will be necessary to collect specimens from 
the type localities in Anticosti in order to determine definitely how j 
wide a range of variation is to be assigned to Beatricea nodulosa. il 
For the present, the specimens here described as Beatricea noduli- \ 
fera are regarded as distinct. I 
A specimen of Beatricea, found at Connersville, Indiana, was j 
identified as Beatricea nodulosa by A. C. Benedict. | 
Beatricea nodulif era-intermedia, var. nov. 
Plate VIII, Fig. 4, A, B. C. 
Among the various aberrant forms of Beatricea found in Ken- 
tucky is one in which the nodes are considerably elongated, form- 
ing short ridges. The upper end of one of these short ridges fre- 
quently terminates slightly to the right or left of the lower end 
of one of the short ridges located farther up the stem, thus result- I 
ing in a vertical serial arrangement similar to that of Beatricea 
nodulifera. It is probably one of the extreme variants of that 
species. i 
Geological position. Near the base of the southern extension | 
of the Liberty bed, in Marion county, Kentucky. |

In the specimen here figured the body has a horizontal diameter , 
of about 75 millimeters, and a vertical diameter of 30 millimeters. I 
However, since only one side of the body is well preserved, its j 
original verticaL diameter is unknown. The preserved sid is 
moderately convex toward the middle. It rested upon clay, and 
was partially imbedded at the time of discovery. It is assumed 
to have been the lower side of the body. If the upper side was ! 
occupied by a large osculum, no trace of the latter is preserved.
