Mr. H. J. Carter on a new Species of Spongilla. 369 
of Berlin, viz. that “the green bodies found in Hydra, 
Spongilla, Stentor, &c.”” do not “correspond to the green 
chlorophyll-bodies of Algz, but are themselves independent 
organisms, unicellular Algw’’ (‘ Nature,’ 1882, vol. xxv. 
p- 377) ; for both Diflugia pyriformis and Acanthocystis tur- 
jacea in England are often found in a colourless state, 7. e. 
without the so-called green “ chlorophyll-cells” (op. et loc. 
eit.) —facts which have been confirmed by Prof. Leidy in his 
memoir on the Freshwater Rhizopods of North America, 
pp- 99 and 267, pl. x. fig. 3, and pl. xliii. fig. 4, respectively

New Species of Spongilla. 
I have now to describe, as far as the specimens will allow, a 
species of Spongilla from the island of Bombay, whose exis- 
tence has only just now become known to me under the fol- 
lowing circumstances, viz. :—On the 8th of March last, Prof. 
Dr. Margo, of the University at Budapest, kindly sent me a 
small jar containing a specimen of Spongilla Cartert from 
Lake Balaton, in Hungary, which he had recognized there ; 
but not having any from Bombay for comparison, he sub- 
mitted the question for my decision. Fortunately, still pos- 
sessing the first and best specimen: I had ever found of it in 
Bombay (viz. in 1847), which in my descriptive account 
I provisionally named S. fréabilis, Lam. (‘ Annals,’ 1849, 
vol. iv. p. 83)—ten years afterwards recognized by Dr. Bower- 
bank as a new species, and named by him “ Spongilla Car- 
tert,” although not described and illustrated by him until 
1863 (Proc. Zool. Soc. p. 31, pl. xxxvui. fig. 20)—I turned 
to this specimen for a bit to send to Dr. Margo, and thus 
came upon the statoblasts of the new species to which I have 
alluded, and which I will now describe, as far as possible, under 
the name of 
Spongilla bombayensis, n. sp. (Pl. XVI. figs. 1-6.) 
General form of the sponge itself unknown to me. Stato- 
blast sessile, globular, more or less grouped and firmly at- 
* A copy of this magnificent “ memoir,” containing forty-eight coloured 
plates of some thousand of figures, evidencing an amount of conscien- 
tious labour almost unparalleled, was liberally sent to me through the 
‘Smithsonian Institution” at Washington ; but of the ‘ Challenger’ Re- 
ports I have only received one paper, and that, too, from a foreign author, 
viz. Prof. Dr. F. E. Schulze, of Gratz, who kindly sent me one of the 
“extra copies” of his contribution on Huplectella aspergillum, although 
at my own cost and labour I had long since published descriptions and 
illustrations of all the sponges dredged on board H.M.S. ‘ Porcupine’ 
from the Atlantic sea-bed in 1869!
