MATERIAL.—PHILIPPINES. Port Matalvi, western Luzon; [15°29′N, 119°56′E]; 23 Nov 1908; 130′ seine: 1 female [6.4].—Cagmanaba Bay, southeastern Luzon; [13°03′N, 123°18′E]; mouth of small stream; 11 Mar 1909: 1 ovig female [6.1].—Port Busin, Burias Island; [13°08′, 122°58′E]; tide pool; 8 Mar 1909 (0800); copper sulfate: 1 female [4.3].—South of Panay near sta 5184; surface under seaweed; 30[?] Mar 1908 [labeled “3/20/08”]: 1 juv [1.2].

RANGE.—Red Sea and South Africa to Japan, Philippines, Indonesia, Australia, New Zealand, and the Atlantic Ocean from Newfoundland to the Falkland Islands in the west and from the Mediterranean to the Tropic of Cancer in the east; associated with floating weed in the open sea and with attached vegetation in shallow water. The species is commonly believed to frequent all tropical and subtropical seas, except those off the Pacific coast of America, but the easternmost Pacific records in the literature seem to be those from New Zealand, and there are no identified specimens in the Smithsonian collections from the Pacific east of the Palau Islands.
