ASCIDIANS OF THE PHILIPPINES — VAN NAME. 61 



All these five stations were in shallow water in the Sulu Archi- 

 pelago, the first four of them near Jolo. The great abundance and 

 variety of ascidians in the Sulu Archipelago is also proved by the 

 results of the Siboga Expedition, which found several localities there 

 where a number of forms were collected, although the collecting sta- 

 tions of that expedition in the archipelago were few in number. 

 This does not of course prove that equally favorable localities may 

 not exist in the more northern parts of the Philippine group, but if 

 so they have not yet been found. 



A list of stations where ascidians were obtained by the Albatross 

 expedition with the species collected at each is here given. Full 

 details in regard to these stations are given in the Dredging and 

 Hydrographic Records of the U. S. Fisheries steamer Albatross 

 during the Philippine expedition, 1907-1910 (Bureau of Fisheries 

 Document, No. 741, Washington, D. C, 1910).
