- Abstract
A new centric diatom, Microsiphona potamos gen. et sp. nov. (family Conscinodiscaceae), is described from the Little Miami River, Cincinnati, Ohio, where it occurred at cell densities ranging from 29 to 20, 140/ml in surface grab samples during the period May 18-December 14, 1966, contributing an average of 11% and a maximum of 35% of the centric diatoms. This species has been observed in grab samples from rivers throughout the United States. The cells are 3-4 μ in diameter, 4-8 μ long, and contain 2 to several plate-like chromotophores. They occur singly, or are held together in short chains by the old girdle bands and by numerous apiculi that connect the opposing valves of adjacent daughter cells.
