THE SPONGE 



The sponge specimen (contained in bottle 8165) 

 which was collected in April 1929 on the reef at Apia, 

 Samoa by the Carnegie party belongs to a very common 

 genus, usually called Reniera or Challna. Both names 

 were given in 1862, the former by O. Schmidt and the 

 latter by Bowerbank. A previous name is Haliclona 

 Grant 1841, but no one has used this name since, so far 



as the author knows, unless very recently. The species 

 is very close to the cosmopolitan cinerea Grant 1827, 

 and may be so identified. It is, then, either Haliclona 

 cinerea (Grant) new combination or Reniera cinerea 

 (Grant) Schmidt. The decorous procedure would seem 

 to be to use the latter name.
