I9I5.] N. ANNANDALE: Phylactolaematous Polyzoa., 167 
One colony examined seems to have overwhelmed a colony 
of Plumatella emarginata. The latter, which has assumed the 
Alcyonelloid form, has managed to keep a small space clear for its 
more vigorous branches in the midst of the Australella. 
Mr. Baini Prasad has given me the following notes on the 
occurrence of A. indica and on some species found in the same 
environment. 
“On the occasion of a recent visit to Ferozpore I collected 
some material from the stagnant rainwater pools that abound on 
the banks of the river Sutlej mostly near the Kaiser-i-Hind 
railway bridge. The following representatives of the three classes, 
Sponges, Hydrozoa and Polyzoa were found. 
SPONGES. 
Spongilla cartert, Carter (Bowerbank 77 Jitt.). 
Large masses of this sponge were found in two ponds, some 
measured more than a foot in length. Large dried-up masses 
consisting of spicules and gemmules only were found in another 
place where the water had quite dried up. 
Spongilla lacustris subsp. reticulata, Annandale. 
Large flat masses of this sponge of a bright green colour were 
found attached to the stems and leaves of Potamogeton. The 
pond was in an open place with no shade at all. 
HYDROZOA. 
Hydra oligactis, Pallas. 
Oniy a single specimen of this form was found. It was 
attached to a Potamogeton leaf from the same pond in which 
Spongilla lacustris subsp. reticulata had been found. ‘The specimen 
has only four tentacles and one bud, which shows the rudiments 
of the tentacles. 
POLYZOA. 
Australella indica, Annandale. 
Large masses of this polyzoon were found in the same pond; 
these were covering the Potamogeton stems and leaves. Most of the 
individuals, however, were dead and large numbers of statoblasts 
had developed in them.’’

(Zool.) XX, p. 62. 
So far as I can judge from the specimen before me, this species 
differs from A. indica mainly in the following characters :—
