collected it from two islands of the Galapagos archipelago, 

 namely Albemarle and Tower. 



10. Geodia gibbcrosa Lamarck 1815, p. 333. One specimen, collected 



August 6 at Old Providence Island, Caribbean Sea. This 

 species was originally described from the West Indian region, 

 where it is widespread and abundant. 



11. Tethya diploderma Schmidt 1870, p. 52. One specimen, collected 



August 6 at Old Providence Island, Caribbean Sea. This 

 species was originally described from the West Indies, where 

 it is very widespread and common. 



12. Leucosolenia canariensis Miklucho-Maclay 1868, p. 230. One 



specimen collected at Old Providence Island, Caribbean Sea, 

 August 6. This species was described originally from the 

 Canary Islands, and recorded as being also West Indian by 

 de Laubenfels in 1936. The specimen in the present collection 

 has remarkably large triaxons, and remarkably few tetraxon 

 spicules, but otherwise agrees rather well with the specimens 

 previously described. 



13. Oligoceras ( ?) sp. Three small specimens of Keratosa were col- 



lected August 6 at Old Providence Island. No one of them is 

 large enough for satisfactory identification.
