SAVILLE K E N T , F.Z.S., F.R.M.S., & c , of the Geological Department, British Museum. [Received June 19, 1871.] (Plate XLVIII.) I am indebted to Dr. J. E. Gray for permission to describe the two remarkable Sponges figured in the accompanying plate. As they agree with one another in their histological and more general fundamental structure, I have no hesitation in regarding them as generically identical, though, in the absence of a published account of any closely approximating form, it becomes requisite to establish a new genus for their reception. |
