This interesting species which Lauder has described and figured in 1863, has been forgotten for long time; Cleve has now pointed out that it is a distinct species and I am of the same opi- nion. I think it must be the same species which Castracane in his report on Challenger-Dia- toms has figured and named B. varians var. princeps and also his figure PL 29, f. 1 of B. spirillum belongs hereto. The fig. 9 illustrate this species. 1 (rr) - 3 (r) - 6 (+) - 10 (+). Area: Malay Archipelago, South China Sea. 38. B. varians Lauder, Trans. Micr.
