No. 11. — Some Japanese and East Indian Echinoderms. By 

 Hubert Lyman Clark. 



The Museum of Comparative Zoology received in the autumn of 1907 

 a collection of Echinoderms made by Mr. Thomas Barbour at Amboina 

 and several other islands in the Dutch East Indies, including Dutch 

 New Guinea. There are 36'2 specimens in this collection, representing 

 thirty-two species, and while none of them is new to science, some are 

 new to the Museum collection and many are of interest because of the 

 localities where they were collected. The value of these specimens is 

 greatly enhanced by Mr. Barbour's notes on their color, habitat, and 

 appearance in life. 



From Mr. Alan Owston the Museum has purchased an interesting lot 

 of Echinoderms, consisting of 153 specimens, representing forty species, 

 of which eight are new to science. The following pages give an anno- 

 tated list of the seventy species contained in these collections and indi- 

 cated as the Barbour collection and the Owston collection respectively, 

 arranged systematically, with descriptions of the new forms.
