Subfamily : HELIASTERINAE. 



Genus: HELIASTER Gray. 

 Heliaster multiradiatus (Gray). 



Plate 57, text figure 3. 



Type: Gray's type came from Hood Island, Galapagos, and is 

 deposited in the British Museum. 



Distribution: Restricted to the Galapagos Islands; reported from 

 Hood Island, Chatham Island, Albemarle Island and Charles Island. 



Material examined : One young specimen from Webb Cove, Albe- 

 marle Island, Galapagos, February 3, 1928, collected by the "Ara," 

 William K. Vanderbilt, commanding. 



Color: Leipoldt in 1895 gave the first color record of this species. 

 The abactinal surface is creamy, yellowish or light gray, irregularly 

 blotched with dark gray or blackish on the rays; the dark blotches 

 appear as cross-bands. The abactinal spines are yellowish, whitish 

 or brownish. The actinal surface is dominated by yellow, but the 

 interbrachial areas and on the proximal half of the rays the outer 

 side of the adambulacral are blackish markings. There is a striking 

 contrast between the inner and outer sides of the adambulacral series 

 and also between the basal and distal halves of each individual spine 

 on its outer side. The oral spines are usually dark on the external 

 side. The madreporite is yellow or creamy white. 



The "Ara" specimen, preserved in alcohol, shows the abactinal 

 surface alternately banded with purplish black and creamy color, in 

 the proportions indicated in the plate. 



Remarks: Dr. Hubert L. Clark's very thorough discussion of this 

 species in his report on ' ' The Starfishes of the Genus Heliaster, ' ' Bul- 

 letin Museum of Comparative Zoology, LI, p. 47, pi. 4, fig. 1, is based 

 on a series of specimens. 



Technical description: Young starfish: Rays 24. Rays about 60 

 per centum free. R = 35 — 26 ; r = 15 — 12. Dr. Clark recorded 

 specimens approximately three times as large as the "Ara" specimen.
