2. Statoblasts armed (normally) with 
hooked processes. 
A. Processes confined to the ex- 
tremities of the statoblast ; zo- 
aria remaining separate through- 
out life oa .. Lophopodella. 
B. Processes entirely surrounding 
the statoblast ; many zoaria em- 
bedded in a common gelatinous 
investment so as to form large 
compound colonies .. ax Pecinatella: 
Those genera of which the names are enclosed in square brac- 
kets have not been recorded from India, while the occurrence of 
Lophopus in this country is doubtful. Plumatella is represented 
by at least four European species as well as by two peculiar, so far 
as is known, to the Oriental region. Of the latter, one has only 
been recorded from a single locality in the Bombay Presidency, 
while the other was originally described from Java. Lophopedella 
and Pectinatella are each represented in the Indian fauna by a 
single species ; that of the former genus occurring also in E. Africa 
and being specifically identical with a race found in Japan, while 
that of the latter is only known from India and Burma but has a 
very close Japanese ally. 
Genus PLUMATELLA, Lamarck. 
Zoarum recumbent or partially upright, branching freely, 
often in two planes. Zowcia cylindrical, arising directly the one 
from the other, sometimes upright, greatly elongated and aggluti- 
nated together ; at least the older zocecia in each zoarium commonly 
recumbent. Statoblasts frequently of two kinds, free and fixed ; 
the latter devoid of air-cells and fastened to the support of the 
zoatium ; the former surrounded by a well-developed ring of air- 
cells, without processes at the periphery, never more than about 
o°6 mm. in length, oval in outline. Polypide never with more than 
about 60 tentacles. 
Hardly any two authorities are agreed as to the number of 
species and varieties that should be recognized in this genus, and 
it is generally believed that the zoaria exhibit very great individual 
variation. Observations, however, carried out on a considerable 
amount of European material as well as a large Indian collection, 
make me inclined to believe that this is not the case, but rather that 
a considerable number of forms exist which breed remarkably true 
even in very diverse conditions. The fact that it is possible to recog- 
nize the majority of the well-established European ‘‘ species ’’ among 
in a structureless gelatinous mass. Statoblasts oval, without hooked processes, 
intermediate in size between those of Lophopus and those of Plumatella. Type
