Localities —Station 5143; in the vicinity of Jolo (Sulu) ; Jolo Light 
bearing 8. 50° W., 3.4 miles distant (lat. 6°05’50’” N., long. 121°02’15’’ 
E.) ; 35 meters; coral sand; February 15, 1908. Two specimens. 
Station 5159; Tawi Tawi group, Jolo Archipelago; Tinakta Island 
(N.) bearing N. 82° W., 1.4 miles distant (lat. 5°11’50” N., long. 
119°54’00’’ E.); 18 meters; coral sand; February 21, 1908. Three 
specimens. 
Remarks.—The two specimens from station 5143 and two of those 
from station 5159 are naked tests, without the apical system. The 
identification of these specimens is not fully certain. The third 
specimen, from station 5159, is a fairly well preserved adult 10 mm. 
in diameter. The color is a light brownish, mottled with greenish 
olive. The spines are very light greenish, with a narrow brownish 
band distally. The very few spines that are not broken have a slight 
terminal swelling. There can be no doubt that this specimen is a 
typical 7’. siamense.
