Of these four are synonyms of previously described forms, and two 

 are synonyms of a species described in the same paper, leaving- five 

 as the total of actual new species. 



Carpenter incorporated the data published in this paper in his 

 Challenger monograph (1888), and, by inserting his supposed new 

 species in his specific keys, indicated their relationships with allied 

 forms. 



In the preparation of his memoir upon the comatulids of the Indian 

 Ocean, Dr. Clemens Hartlaub also visited the Hamburg Museum, 

 examining Carpenter's types and studying the specimens which had 

 been received since Carpenter's visit. In his preliminary paper ( 1890) 

 he included descriptions of twelve new species, seven of which were 

 exclusively and five in part based upon material at Hamburg. The 

 new species described by Hartlaub (with their present determina- 

 tions) are as follows: 



Actinometra macrobrachius Capillaster macrobrachius 



Antedon crassipinna (part) Himcromctra magnipinna 



Antedon kraepelini Himerometra ( ? species) 



Antedon nematodon Amphimetra nematodon 



Antedon oxyacantha (part) Stephanomctra oxyacantha 



Antedon monacantha (part) Stephanomctra monacantha 



Antedon erinacea Oxymetra erinacea 



Antedon lepida Dichromctra protectus 



Antedon tenera (part) Dichromctra gyges 



Antedon afra Tropiomctra afra 



Antedon hupfcri Antedon hupferi 



Antedon nana Iridomctra nana 



Of these one is not sufficiently well preserved to be determinable, 

 two are synonyms of previously described species, and one, a type in 

 part, is not the same species as that represented by the remainder of 

 the type material, leaving eight as the total of actual new forms. 



In the finished memoir (1891) Hartlaub elaborated his preliminary 

 descriptions of these new species, publishing figures of most of them.
