radial chambers are laucli Viraiiclied, which I believe is 

 what Mr. Carter means when he says that they intercom- 

 municate by lai-ge holes. The branches run parallel with 

 one another to the dermal cortex ; the exhalant canals are 

 short.

 The last five species are described by Mr. Carter apparently 

 from single specimens, all collected by Mr. Wilson. It appears 

 to me very doubtful whether they are all specifically distinct, 

 and also whether some of them at any rate are not mere 

 varieties of G. inoculum or Vosmaeropsls macera, which 

 they resemble in spiculation. Unfortunately, I have not 

 seen any of the types.
