JAPANESE ASTEKOIDEA. 383 



en vor, von welchen aber die inneren kaum grösser sind als die äusseren, 

 wie es beim Typus der Fall ist." 



In the copy of tliis paper which I owe to the kindness of the author 

 a manuscript note is added to the effect that according to Dr. ICœhler, 

 the form described in the above passage belongs to ArchrMerpctrelii var. 

 longobracldalis Dan. & Koren, but that it reaUy belongs to the genus 

 F seiidar chaster {Ästrogonium) . 



Fm-ther references to this species are : Appellöf [Archcister parelii, '96, 

 p. 11 ; '97, p. 13] and Geieg [Plutonaster parelii, '96, p. 5, 12 ; '97, p. 37]. 

 The latter says in one place [ '96, p. 5] : 



" Af denne ved vore kyster spar- 

 somt ox3tra3dende art har jeg fundet 

 nogle faa eksemplarer ved Ves0, Skœr- 

 gehavn (60-80 fv.), Hus0en (200 fv.) 

 og Granesund (80 fv.). Hansen og 

 Friele har den fra havet udenfor 

 Sognefjorden og fra Batalden, 250 

 fv." 



Of this species which occm's 

 sparingly on our coasts, I have found 

 a few examples in Vesji, Sk?ergehavn 

 (60-80 fath.), Husten (200 fath.) and 

 Granesund (80 fath.). Hansen and 

 Friele have it from the sea outside 

 Sognefjord and from Batalden, 250 

 fath.

Sladen ['97, p. 78] mentions it under the name of Plutonaster {Tethyas- 

 ter) parelii from Kockall Island. 



Yerrill again describes Pseudar chaster intermedim Sladen as follows 



[ '99, p. 190, 3 figs.] : 



" This is the most common species off the eastern coast of the United 



States and Canada. 



" It was taken at about 33 stations by the Albatross and Fishhawk, 

 1880 to 1887, in 85 to 1608 fathoms, from N. lat. 44° 26' to 37° 59' 30. 

 It has been brought from the fishing banks, off Nova Scotia, by the Glouces- 

 ter fishermen. 



" The variety {insignis) namsd and described by ms in 1895, is probab- 

 ly only the full adult form of this spacies. The largest example has the 

 larger radius, 75 mm ; the lesser, 23 mm. It lacks distinct actinal fascioles. 

 These exist, however, in variable numbers, on other similar specimens, of 

 somewhat smaller size, as well as on quite yoimg examples. Their presence 

 does not depend upon age, for they may be absent or present in specimens
