Scyphidia micropteri, a new protozoan parasite of largemouth and smallmouth black bass
E. W. Surber
1940, Transactions of the American Fisheries Society (69) 169-175
A small urn‐shaped peritrichous protozoan, apparently an undescribed species, was found on the gills and bodies of largemouth and smallmouth black bass in ponds at Leetown, West Virginia. A heavy mortality among a lot of fingerling largemouth bass probably resulted from suffocation due to the organisms on the gills. Specimens...
Ridge-making thin sandstone in Frederick County, Virginia: Chapter C
R.S. Edmundson
1939, Book chapter, Contributions to Virginia Geology--II
It is generally recognized that massive thick-bedded sandstones and relatively weak shales and soluble limestones form characteristic surface features.

A largemouth black bass fingerling preserved in formalin was sent to the U.S. Bureau of Fisheries Pathology Laboratory at Seattle, Washington, during the autumn of 1937, by a hatchery employee at Miles City, Montana. The fish exhibited several wart-like protuberances on the caudal peduncle, which aroused the curiosity of Mr....
