of the Muséum d'historié ua,tm-elle of Paris. He tlien refers to the original 

 specimens as follows ['76, p. 279] : 



"Deux échantillons desséchés et en bon état, sans date d'entrée et 

 sans provenance. Ce sont les types de Müller et Teoschel." 



Slyden describes a small specimen of Astropecten jcqjoniciis ['79, p. 427] : 



" Astrojpeden jajponicus, Müller and Troschel. 1842. Astropsden japoni- 

 cus, Müller and Troschel, System der Asteriden, \). 73. 



" Coll. St. John : Korean Straits, 9 fathoms. 



"The arms are moderately long and narrow; 11 = 11.25 millims., r=4 

 millims. The foot-papillœ, arranged in wedge-shaped groups of five, are 

 long, fine, and cylindrical. The first spinelet, which forms the apex of the 

 wedge, stands by itself, i)i'OJecting inward upon the furrow, is tliicker than 

 the rest and arched upwards at its base ; the others stand external to tliis, 

 two and two together, the outermost pair being rather longer than the inner 

 pair; whilst on the inmost x)ortion of the furrow the outer series of papillse 

 are augmented by one or two additional spinelets. The adambulacral plates 

 wliich bear the foot-papillse appear very much depressed, in consequence of 

 the gibbous character of the ventro-marginal plates — a featm'e wliich is very 

 striking when compared, for instance, with specimens of Astr. formosus, 

 mihi, of nearly equal size. 



"The uj)per marginal plates are broader than long, and covered closely 

 with shoi-t stout gi-anulose spinules of clavate form, and on tlie outer half of 

 the arm carry on their outer margin a small conical spinelet. In the 

 specimen under notice the nine outer, out of thirteen marginal plates, are 

 thus armed. 



" The ventro-marginal plates project more outwardly than the upper 

 marginal plates, and bear one large, compressed, lanceolate spine at the 

 margin, which is generally followed by two smaller spines placed side by 

 side, not half its lengtli, and ver}^ much finer and more cylindrical. The 

 rest of the spinulation consists of small, short, isolated, cylindrical spinelets. 

 In the present example these have been very much abraded ; and little 

 further detail can be made out.
