The discovery of this species makes it necessary to modify the diagnosis of the genus, the essential character of which, as distinguishing it from Plumatella, is the differentiation of the proximal part of some or all of the zoœcia to form stolon-like tubules. From Stephanella, Oka, it is distinguished by the absence of a gelatinous covering, and by the fact that all the zoœcia are attached, at least at the base, to some extraneous object.
Habitat. Malwa Tal, Kumaon (alt. 3600 feet), W. Himalayas (Kemp, May 1911).
Biology. Mr. Kemp took three specimens, all attached to the lower surface of stones. They contained few statoblasts and were evidently in a condition of vigorous growth. Between the lateral branches new polyparia were developing in several instances from free statoblasts, each of which appeared to contain two polypides.
[BP] Most of the forms assigned by Potts to this species belong to the closely allied E. mülleri (Lieberkühn).
