Abstract
Several species and genera of very small diatoms have been isolated from Gulf of Mexico waters at Galveston. A quantitative and qualitative study of their distribution has not yet been made. The organisms were isolated in unialgal cultures, and very rapid growth rates were observed. Environmental and experimental implications are pointed out. A new species, Chaetoceros galvestonensis, 1.5 by 3.0 microns in broad view, is described and figured.
