BO MEA: VY PRES I DENCY: 
By N. ANNANDALE, D.Sc., F.A.S.B., Superintendent of the 
Indian Museum. 
Mr. F. H. Gravely of the Indian Museum and Mr. S. P: 
Agharkar of the Elphinstone College, Bombay, have recently 
obtained many specimens of the medusa referred to on p. 144, 
vol. Ixxxvii of Nature. The following preliminary description is 
based on an examination of these specimens, which are several 
hundreds in number and come from the Yenna and Koyna 
valleys in the Satara district of the Bombay Presidency. 
LIMNOCNIDA INDICA, Sp. nov. 
This medusa is closely allied to L. tanganicae (Bohm)! and 
L. rhodesiae, Boulenger,* but differs from both in the arrangement 
of its tentacles and sense-organs. 
Dimensions.—The smallest specimen (fig. 1) I have seen is 
about 1°75 mm. in diameter and has probably been, at any rate 
when in a state of contraction, at least as deep as broad. Full- 
grown meduse are I5 mm. in diameter and almost three times as 
broad as deep. 
Fic. 1 —Young medusa of Limnocnida indica. 
Umbrella.—The umbrella is very shallow and almost flat 
on the dorsal surface in the adult; in the young it is distinctly 
flattened above but not so broadly as in the adult.
