S. coggint is evidently a close ally of S. clementis, which was 
discovered, together with S. philippinensis, in Lake Lanao in the 
Philippines. S. clementis, however, has smooth skeleton spicules 
and the gemmule is armed with microscleres. It is interesting 
that the two sponges found in Lake Ta-li Fu should be so like the 
two from Lake Lanao, but our knowledge of the fauna of both 
lakes is still incomplete. 
POLYZOA. 
? Plumatella javanica, Kraepelin. 
A dried specimen from Mong Pan, taken together with the 
specimen of S. proliferens referred to above, appears to belong to 
this form, which is common in northern India and Burma.
