Locality. King Island (native name Padaw) ; Jan. 1882 ; sub- 

 littoral. 



Remarks. This handsome form was described and figured by 

 Linne in the ' Museum Tessinianum ;' and the same example is 

 stated by Liitken* to have been the original of Seba's figure in 

 his ' Thesaurus,' t. iii. pi. 6. figs. 7 & 8. Until four years ago 

 the species — excepting the existence of the well-preserved type — 

 might be said to have been lost sight of, and its locality was 

 unknown. 



In 1884, M. P. de Loriol gave a careful description and 

 excellent figures of an example collected at Singapore ; he also 

 discussed the erroneous views of previous writers on the species 

 in question. With M. de Loriol's determination I entirely 

 agree ; and his description accords closely with the notes which I 

 made when examining the Linneau type of Asterias articulata in 

 the University Museum at Copenhagen. 



The specimen collected at Mergui by Dr. Anderson is inter- 

 mediate in size between Linne's specimen and that described by 

 de Loriol, the measurements being R = G(i mm., r=34 mm. In 

 general outline it approaches more nearly to the type thaii does 

 de Loriol's large example, the interbrachial arc being more 

 widely rounded, which causes the rays to appear rather more 

 defined. In other respects the Mergui example accords closely 

 with the description of that from Singapore ; and I feel no doubt 

 as to the specific identity of the three examples.
