MARINE ISOPODS COLLECTED IN THE PHILIPPINES BY THE 

 U. S- FISHERIES STEAMER ALBATROSS IN 1907-8.

Our knowledge of the Philippine isopods is limited to a few species. 

 No one paper has been published treating exclusively of the forms 

 from those islands, but in a number of papers and general works 

 mention has been made occasionally of an isopod from the Philip- 

 pines. The first author who described a Philippine isopod was Carl 

 Semper, in 1868, and he described the species known as JEga spongi- 

 ophila, which was found living in a sponge, Euplectella aspergillum. 

 Hobby Kossmann in 1872 described a number of Bopyridse. Later 

 J. C. Schioedte and Fr. Meinert in 1879-84 and Semper in 1880 

 described other isopods from the Philippines. 



Only four of the known species previously recorded from the 

 Philippines were collected by the Albatross expedition in 1907-8; 

 these are Probopyrus aseendens Semper, Rocinela orientalis Schioedte 

 and Meinert, Cymothoa stromatei Bleeker, and Mga spongiophila 

 Semper. Many of the species collected there at this time, however, 

 have been already described and recorded from other places not far 

 distant, such as Japan, Java, Ceylon, Sulu Sea, Nicobar Islands, 

 New Guinea, Isle of Pines, New Britain, India, Amboina, the Society 

 Islands, Singapore, Hongkong, etc. These known species were 

 described by the following authors: Leach, in 1818; Dana, in 1853; 

 Bleeker, in 1857; Miers, in 1878-1884; Hansen, in 1890; Bonnier, in 

 1900; Stebbing, in 1902-1905; and Nobili, in 1906. The works 

 of other authors have been studied in this connection: H. Milne Ed- 

 wards, Haswell, Whitelegge, Filhol, Hilgendorf, Thomson, Koe|>el, 

 Lanchester, Bouvier and A. Milne Edwards, Beddard, Baker, 

 Haller, Chilton, Heller, Max Weber, etc. 



In addition to the known isopods collected by the Albatross in the 

 Philippines this expedition obtained thirty-eight species new to 

 science, three of them the types of new genera.
