This species, wliich was found by the Challenger in its best develop- 

 ment off the Admiralty Islands, and which are allied in their faunal 

 characters with that of the Philippines, has occurred at two stations 

 in the Sulu Archipelago, D5146, off Siasi, in 24 fathoms (44 meters), 

 and D5154, off Tawi Tawi, in 12 fathoms (22 meters). The speci- 

 mens were not common.

This species seems to be a common one in the Philippine material. 

 It is a characteristic species of the coral-reef regions, and is also found 

 to considerable depth. There seem to be two forms which are char- 

 acterized by the ornamentation of the test. One of these has the 

 test with coarse reticulate ornamentation and large intermediate 

 portions; the other is very thinly perforate. This latter form occa- 

 sionally has a secondary thinning of the wall, developing large 

 papillae. 



Similar specimens are found in the region about New Zealand, 

 and the two may represent distinct species. 



Tliis species has been found at 25 stations in the area, abundant 

 at some of them; these range in depth from 18 to 890 fathoms (33 to 

 1,628 meters), the average depth being 190 fathoms (348 meters). 



Bottom temperatures range from 46.2° F. to 75.7° F. (7.8° C. to 

 24.2° C), with the average 54.6° F. (12.5° C). These stations are 

 mostly in the region of the Archipelago, although it is common in 

 the Sulu region and also to the southward in Darvel Bay, Borneo, 

 and Buton Strait.
