96 Records of the Indian Museum. [VoL. XVIII, 
Locality.—Our specimens were found on the stems of bul- 
rushes in the reed-beds of the Hamun-i-Helmand near Lab-i-Baring 
in December, 1918, with Fredericella sultana and Ephydatia flu- 
viatilis.

Kraepelin gives in the work cited a useful key to the species 
and figures the statoblasts. He points out that the African species 
hitherto confused with L. carteri is distinct, and describes it under 
the name L. stuhlmanni. He also describes a new variety of 
L. capensis (Sollas) under the name var. michaelsent. The forms 
that must now be referred to the genus are L. cartert (Hyatt), 
L carteri subsp. davenporti (Oka), L. thomasi, Rousselet, L. cap- 
ensis (Sollas), L. capensis var. michaelsent, Kraepelin and L. stuhl- 
manni, Kraepelin. ‘The range of the genus extends from Eastern 
Persia to Japan, Brazil and South Africa, but is mainly tropical. 
The following key, though not actually based on Kraepelin’s, owes 
much to it. 
Key to the species of Lophopodella. 
1. Each extremity of the statoblast produced into a long 
slender process bearing books along each margin ... L. capensis. 
2. Extremities of statoblast truncate or subtruncate, with a 
single row of hooked processes. 
A. Extremities of statoblast broadly truncate, little 
narrower than the greatest transverse diameter .., L. stuhlmannt. 
B. Extremities of the statoblast broadly rounded, much 
narrower than the greatest transverse diameter ,,, L. cartert. 
C. Extremities of the statoblast very narrow, concave L. thomast. 
All of these species except L. carteri are African.

Specimens from an irrigation channel in the Consulate garden 
at Nasratabad, Seistan agree well with Indian specimens. Stato- 
blasts were also taken, with gemmules of Spongilla carteri and 
S. alba, amongst drift at the edge of a pool in the desert in the 
same district. The statoblasts did not differ in any respect from 
those of Indian colonies. 
Statoblasts were found in active colonies in all stages of 
development in December. The animal was living among green fila- 
mentous algae. The most interesting feature of these colonies was, 
however, that each was attached to a fine mucilaginous tube and 
that each tube was inhabited by a small Oligochaete worm
