INTRODUCTION 



The territory covered by the dredging stations worked by the 

 United States Fisheries steamer Albatross during her Philippine 

 cruise of 1907-1910 was somewhat more extensive than the Philip- 

 pine region proper, extending from the most northerly station 

 which was in the China Sea, vicinity of Hongkong, latitude 21° 

 54' N., longitude 114° 46' E., which is some 500 miles northwest 

 of the Philippines proper ; the vessel worked as far south as Borneo 

 near Sudakan at about latitude 4° 30' S., longitude 118° E., which 

 was also about the farthest west at which work seems to have been 

 done and hydroids taken, with the exception of Hongkong. The 

 extreme southern limit in the Philippines seems to have been at Tawi 

 Tawi group of the Sulu Archipelago where stations were worked as 

 far south as latitude 4° 58' 20" N., and the most southerly station of 

 all yielding hydroids was in Macassar Strait, latitude 4° 43' 22" S. 

 There was, therefore, a range of over 26° of latitude between the 

 extreme northern and the extreme southern stations yielding 

 hydroids. 



It may be of interest to note the regions in which the most 

 hydroids as indicated by the results of the dredging were found: 

 China Sea, vicinity of Hongkong, at station 5310, five species were 

 secured; at station 5311, six species; at station 5312, four species. 

 In the Sulu Archipelago, vicinity of Siasi. hydroids were taken at 

 all live hauls. Between Samar and Leyte, vicinity of Suriogo 

 Strait, there were five hauls at which hydroids were taken. 



The greatest depth represented by specimens in the collection 

 was at station 5428, Eastern Palawan, 30th of June Island, N. 62°, 

 W. 19.5°, depth 1,105 fathoms, where two species IHctyocladivm 

 aberrans and SertulareJla comuta were secured. Stegopoma plicatile 

 was dredged from 441 fathoms at station 5529, 9° 23' 45" N., 

 123° 39' 30" E. Zygophylax convallaria came from a depth of 400 

 fathoms at station 5635, Pitt Passage, 10° 53' 30" S., 127° 39' E.;
