JAPANESE ASTEROIDEA. 159 



study of tli3 larga ssries of sp3clm3ns from Australia, I have no hesitation 

 whatsver in regarding the name as a synonym of the present species, 

 although the type-specimen could independently be scarcely held as available 

 for specific recognition. I have also examined the types of Grube's Astro- 

 pecten cJimensis and Astropecten ensifer in Breslau, and I consider that both 

 of them are with little doubt young stages of Astropsden poly acanthus." 



Ives simply mentions the name of Astropecten armatus without figure or 

 any definite locality ['91, p. 211]. 



De Loeiol ['93, p. 379] mentions " un exemplaire très typique dans 

 lequel 11 = 57 mm." from the Bay of Amboina. It is mentioned by Bell from 

 North-west Australia (32-34: fms.), Arafura and Banda Seas (12-15 fms.) and 

 Macclesfield Bank (30-11 fms.) ['94, p. 394, 395, 396]. 



Sluiter mentions this sx^ecies from the Red Sea and the Moluccas 

 ['95, p. 53] : " Astropscten polyacanthus M. und Te. Ein Exemplar von dem 

 Koten Meer und zwei von den Molukken (v. d. Hucht), aUe getrocknet." 



Leipoldt refers to this species as follows ['95, p. 645] : " Ein Exemplar 

 von Beilul (nordwestlich Assab) aus einer Tiefe von 5 m auf Algengrimd ; ein 

 Exemplar von Assab. 



" Das erstere Exemplar zeichnet sich dadurch aus, dass sämmthche obere 

 Randplatteu einen grösseren Stachel tragen, während bei dem anderen, 

 kleineren Exemplare die zweite obere Kand^^latte ilm nicht besitzt." 



Kœhlee mentions this species from the Suuda Isles ['95, p. 387] : 

 " Plusieurs échantillons de petite taille, mais très typiques." Pfeffee ['96, 

 p. 47, ßde Zool. Rec] remarks on its colom-. Farquhae ['98, x^. 310] gives 

 its distribution as follows : New Zealand, Australia, Admiralty and Fiji Islands, 

 Japan, China, Ceylon, Andaman Islands, Bay of Bengal, Mamitius, Bed Sea. 



It is mentioned by Ludwig from Zanzibar, although not represented in 

 the collection reported on ['99, p. 538] :

 Pereiee (1875), von Peeffer (1896), von den Amiranten und Seychellen 

 dui-ch Beü (1884)."
