This species was obtained at five stations, all in shallow water, in 

 the Sulu Archipelago, where it appears to be common. 



No. 49. Station D5141 (off Jolo Light, Fob. 15, 190$, 29 fathoms, coral 



sand). One colony. (Cat. No. 0905, U.S.N.M.) 

 No. 39. Station D5139 (off Jolo Light, Feb. 14, 1908, 20 fathoms, coral 



sand). Several colonies. (Cat. No. 5907, U.S.N.M.) 

 No. 36. Station D5147 (off Sulade Island, Sulu Archipelago, Feb. 1G, 1908, 



21 fathoms, coral sand and shells). One small colony. (Cat. No. 



5925, U.S.N.M.) 

 No. 115. Station D5148 (off Sirun Island, Sulu Archipelago, Feb. 16, 190S, 



17 fathoms, coral sand). Two large colonies. (Cat. No. 5975, 



U.S.N.M.) 

 Nos. 58, 65, 134. Station D5149 (off Sirum Island, Sulu Archipelago, Feb. 



IS, 1908, 10 fathoms, coral and shells). Five colonies. (Cat. 



Nos. 5906, 5908, and 5974, U.S.N.M., respectively.) 



Herdman (188G) describes this species (which he himself suggests 

 is none too well distinguished from the previously described Mediter- 

 ranean forms II. pileata, O. Schmidt, 1862, and II. rosea Delia Valle, 

 1881), from latitude 6° 54' N.; longitude 122° 18' E., 10-20 fathoms. 

 He also reports it from Tangier Bay, Morocco, 35 fathoms.

In the only specimen the colony is of inverted conical form, meas- 

 uring about 14 mm. across the top, which is only slightly convex, 

 and 17 mm. in height, exclusive of the pedicel on which it is borne. 

 The pedicel is 3 to 4 mm. in diameter and about 34 mm. long in 

 its present condition, but the base has evidently been broken off. 



Test opaque yellowish gray in color and somewhat fibrous in 

 consistency. Zooids numerous, arranged in vertical parallel rows on
