On p. 121 is a trivial reference to Heliaster and in a footnote (2) on 

 p. 125 et seq. is an interesting discussion of the correlation between size 

 and number of rays in " Asterias helianthus," " microbrachia," " Kubinjyi" 

 and " Cummingii" — 



1875. Perrier, Edmond. 



Revision de la Collection de Stellerides du Museum d ? Histoire Natu- 

 relle de Paris. Arch. Zool. Exp., 4, p. 265-450. Paris. 



The genus Heliaster Gray is approved and placed in the Asteriadae 

 (p. 285-286) and a diagnosis is given (p. 299). Later (p. 351) it is given 

 as the fifth genus of the Asteriadae, with four species: 



H. microbrachia Xantus. Acapulco. 



H. kubiniji Xantus. Acapulco. 



H. helianthus (Lam.). Chili. 



H. canopus, sp. nov. (Mss. Valenciennes). Juan Fernandez. 

 The writer considers microbrachia the best characterized species, and 

 describes canopus, which he says is 70 mm. in diameter and has only 

 24 rays, and may prove to be the young of helianthus. Perrier does not 

 mention multiradiatus, but states that he could not find Gray's cumingii 

 at the British Museum.
