waters, or among the Molucca Islands. Of these, 47 are new species. 

 Fifty-nine, out of 101 species, occur in the Philippines (8 new), 

 making a total of 149 species for the group, of which only 55 had 

 been described prior to the Albatross expedition. A majority of the 

 65 are here recorded for the first time from the Philippines. 



Eighteen new generic types were discovered by the Albatross expe- 

 dition, while new species have made desirable the segregation of six 

 additional genera and subgenera. 



The new generic types are : 

 Benthogenia, Lithosoma^ Xenorias, 



Astromesites, Astrothauma, Hymenasterides, 



Anthosticte, Atelorias, Bythiolophus, 



Koremaster, Ualityle, Brisingenes, 



Perissogonaster, Dissogenes, Astrostephane, 



Pontioceramus, Tarachaster, Stegnobrisinga. 



The other new genera and subgenera are : 



Ctenopleura^ near Astropecten. 



Paranepanthia, near Nepaiithia and Asterinopsis. 



Glyphodiscus, new subgenus of Iconaster. 



Freyellaster, near Freyella. 



Brisingella^ near Brisinga. 



Craterobrisinga^ near Brisinga. 



During the preparation of this report I have had occasion to draw 

 rather freely upon the collection of the United States National 

 Museum for comparative material. It is a great pleasure to record 

 the liberal cooperation of the Museum authorities and in particular 

 that of Dr. Paul Bartsch and Mr. Austin H. Clark. The collection 

 of the Museum of Comparative Zoology of Cambridge is a treasure 

 house for the systematist, and its facilities have always been most 

 agreeably placed at my disposal, both during visits and by the loan 

 of specimens, for which I am indebted to Dr. Hubert Lyman Clark 

 and Mr. Samuel Henshaw. The holotypes of Asterina coronata 

 cristata and Bunaster lithodes are in the collection of this museum. 



During a brief visit to London I was able to examine a number of 

 types in the British Museum, especially some of J. E. Gray's from 

 Migupou, and for this courtesy I am indebted to Prof. F. Jeffrey 

 Bell. Similarly Professor Joubin gave me access to the starfish col- 

 lection of the Museum d'Histoire Naturelle of Paris, and Doctor 

 Horst to that of the Leyden Museum, and to these gentlemen my 

 best thanks are tendered. Nor should I omit a conference with my 

 genial friend, Dr. Rene Koehler, of the University of Lyon, the lead- 

 ing European authority on Asteroidea and Ophiuroidea. 



As already stated most of the new species brought back by the 

 Albatross have been briefly described. These are contained in papers
