The carinal latus is triangular, higher than wide, the apex curA^edtoAvard the inf ramedian latus. The tAvo latera almost meet at the basebeloAV the carina. The peduncle is coA^ered Avith wide imbricating scales in six verydistinct rows of about fifteen scales each. The scales of adjacent rowsinterlock only shortly. Length of the capitulum 8, breadth mm. Length of the pedun-cle mm. Length of the carina , diameter near base mm. This peculiar little species resembles S. halanoldes in the shortcarina and triangular upper latus, but the carinal latus is short, and.
