SYNOPSIS. Silver impregnation techniques were used to study the silverline system of three species in the genus Spirostomum. It was concluded that for those species studied in the general area of Washington, D.C., the average numbers of ciliary meridians in S. teres, S. minus and S. ambiguum are 18, 24 and 46 respectively. Seventy‐six % of the measurements in S. teres and S. ambiguum and 84% of the measurements in S. minus deviate from the mean by less than 1 standard deviation.
