I described the genus Australella in 1910! in a footnote to a 
paper on Indian Phylactolaemata, but the type-species, which was 
the only one then distinguished, was an Australian form (Lopho- 
pus lendenfeldi, Ridley?) known from the original description 
only. The type-specimen is in the British Museum, whence I 
have been able to obtain a iragment through the kind offices of 
Mr. R. Kirkpatrick. This schizotype was before me when I des- 
cribed the genus, but the shrivelled condition of the colony ren- 
dered it necessary to rely on Ridley’s diagnosis and figures rather 
than on direct observation. Relying, therefore, on this descrip- 
tion, I placed Austvalella in the subfamily Lophopinae. An 
examination of admirably preserved material of a new species 
leaves no doubt now that it belongs to the Plumatellinae, as is 
indicated by Kraepelin’s* recent note on Lophopus jheringi, Meiss- 
ner, which he regards as a congener. 
We owe the discovery of the new species to Mr. Baini Prasad, 
Patiala Research Scholar in the Government College, Lahore, 
whose keenness as a collector and observer is already beginning to 
cast light on obscure places in our knowledge of the aquatic 
fauna of the Punjab. 
The genus Australella may now be defined as follows :— 
Genus Australella, Annandale. 
Plumatellinae in« which the colonies are recumbent and 
dendritic but enclosed in a uniform apparently structureless 
jelly that fills up the interstices between individual zooecia 
and branches. There is no stolon; the zooecia arise directly 
one from another. Individually they are semirecumbent, the 
proximal part of each resting, when the branch to which it 
belongs is fully formed, on the object to which the colony its 
fixed, while the distal part is almost vertical. The polypide
