Of these 25 species it will be seen that 13 were collected by the 

 "Albatross" in 1902. This is in noticeable contrast to the Hawaiian 

 collection of starfishes, of which Dr. Fisher reports that only one of 

 the ten species formerly known from the islands was dredged by the 

 " Albatross." The absence of 12 of the previously recorded Echini is not 

 surprising, as the collections hitherto have been made, with few excep- 

 tions, from along shore, while the collections made by the '' Albatross " 

 in 1902 were from off the shores to deep water. The bathymetrical 

 range of several species is greatly extended, and a few Indo-Pacific 

 species are added to the Hawaiian fauna, which now includes 79 species 

 of Echini. 



As regards the geographical relations of the Echini collected, it is inter- 

 esting to note that of the new species of Cidaridae two are related to the 

 Panamic fauna, the others to the Pacific or Indo-Pacific. The Salenias 

 are Panamic, while the Aspidodiadematidae and many of the Diadem- 

 atidae are Indo-Pacific. In the Echinothuridae we find Phormosoma
