13. Descriptions of three new species of Algz associated 
with Indian Freshwater Polyzoa. 
By Pror. WM. WastT, with notes by N. ANNANDALE, D.So. 
[The alge described in this paper were taken in the Bits 
Lake, near Puri in Orissa, in October 1908, and in Igatpuri Lake 
The specimens examined by Professor West were preserved in 
formalin or spirit.—N. A.]} 
TOLYPOTHRIX LOPHOPODELLOPHILA (W. West), fuscescens, 
floccosa, trich omatibus pseudoramulisque dense intricatis ; cel 
lulis sepe distinctis, interdum indistinctissimis, quadratis vel 
aliquo modo longioribus quam latis; vaginis amplis, subirre- 
gularibus ad marginem; heterocystis 1—3 ad basin pseudora- 
mulorum, oblongo-rotundatis, diametro 1}—2-plo longioribus, 
trichomatis diametro paulo crassioribus. 
In stagnis cum Lophopodella carteri associata. 
[This alga was found coating the stems of shrubs that grew 
in the water at the edge of Igatpuri Lake. It formed irregular 
gelatinous masses of a dark green colour. More or less distinct- 
ly embedded in these masses were numerous colonies of the 
polyzoon Lophopodella carters (Hyatt), a species also found, 
often asec as on the lower surface of stones in the same 
lake. Those colonies, however, which were associated with the 
alga were of unusually vigorous growth, occurred in unusually 
numbers in a comparatively small space, and did not 
avoid the light as the species usually appears to do.—N. A.] 
DACTYLOCOCCOPSIS PECTINATELLOPHILA (W. West), cellulis 
anguste ellipticis, fusiformibus, vel interdum oblique sublanceo- 
latis et subirregularibus, contentu cellularum pallide eru- 
gineis et homogeneis. Lat. cell. 3—5-5 »; long. cell. 8—13 p. 
[The cells of this alga were found embedded in the com- 
mon gelatinous investment of compound colonies of Pectina- 
tella burmanica which encased the stems of reeds growing, in 
very shallow water, in the middle of the Sur Lake near Puri. 
common to several or many colonies. It has hitherto been
