 "ALBATROSS," 1907-1910.— No. 23.] 



FOUR NEW GENERA AND FIFTY-EIGHT NEW SPECIES OF 

 STARFISHES FROM THE PHILIPPINE ISLANDS, CELEBES, 

 AND THE MOLUCCAS. 



By Walter K. Fisher, 



Of Stanford University, California. 



The new genera and species of starfishes described in this paper 

 were obtained from among the Philippine Islands and the neighboring 

 islands to the southward by the U. S. Fisheries steamer Albatross 

 during her cruise o^ 1907-1910. These species will be fully illus- 

 trated and described in greater detail in the final report on the collec- 

 tion, now in course of preparation. 



In a previous paper ^ the following genera, each based on a new 

 species, were described: 



Benthogenia (Porcellanasteridse). Lithosoma (Goniasteridee). 



Anthosticte (Astropectinidse). Atelorias (Goniasteridee). 



Pontioceramus (Goniasteridse). Hymenasterides (Pterasteridse). 



In the present paper the following new genera are characterized: 



Ctenopleura (Astropectinidee, near Astropecten) . 

 Astromesites (Astropectinidee, near Blahiaster). 

 Perissogonaster (Goniasteridee, near Paragonaster). 

 Astrothauma (Goniasteridee, near Calliaster). 



A new subgenus of Dytaster, Koremaster, founded on a new species, 

 Dytaster evaulus, is described. 



A list of the new species and subspecies is given for quick reference. 



PORCELLANASTERIDiE. 



Sidonaster psilonotus. Ctenodiscus orientalis. 



GONIOPECTINID^ . 



Goniopecten asiaticus. Prionaster gracilis. 



Prionaster analogus. Prionaster megaloplax.
