Frustules large, 175â200p broad; squamæ 5 in circumference; spine as in R. styliformis; lines of the connection-surface with two thickened parts for the basal part of the spine; chromatophores numerous, small. This interesting species is allied to R. Debyana Perag. It is the only species besides R. styliformis Btw., which includes the peculiar Richelia intracellular is Schmidt (in Ostenfeld & Schmidt, PI. f. the Red Sea, p. 146, f. 2). 2 (rr) â 5 (rr) - 7 (+) â 10 (rr). 27.
