and Troschel may best be united into one ; so that his divisions are : (1) 

 with a single series of liigh and strong spines on the snperomarginals, (2) 

 with a double series of smaller, both lower and feebler, spines, one along 

 the outer edge, and the other along the inner edge of the snperomarginals, 

 (3) superomarginals simplj^ gi-anular, but not seldom one or two very low 

 spines amid tliis granulation ; strong spines however always wanting in the 

 angles between the arms. Astropecteu japonicus is placed in the last group, 

 and the following remarks is made [Lütken, '64, p. 125, 127] : 



" I have not j'et seen any A. 

 j^entacantltus or A.jcqjonicus with small 



" Jeg har endnu ikke seet nogen 

 A. pentacantlms eller A. japonicus med 

 Smaapigge paa Kandpladerne . . . " 



spines on the marginal plates . 



Von Maetens, in a section of his paj)er of 1865, headed, " Japanische 

 Seesterne," has the following ['65, p. 352] : 



" Astropeden scop)arim Val. Müll. Teosch. 1. c. S. 71. 



" Yokohama, auf Sclilammgrund, nicht häufig, die Stacheln auf den 

 dorsalen Eandplatten sind sein unbeständig, sie felilen im ersten Drittel der 

 Arme fast immer, bis zur Mitte kommen immer noch einzelne Platten olme 

 Stacheln vor." 



At page 354 of the same pa^Der, there is a reference which possibl.y 

 has to do with the original specimen or specimens of Müller aud 

 Troschel.

Again, in his second paper he says ['66, p. 87], " Astropecten scopctrws 

 Müll. Trosch. Indischer Ocean, Schonlees^ im Berliner Museum. 1st 

 sicher in Japan zu Hause." 



According to de Loriol ['85, p. 74] and Sladen ['89a, i?. 324] Astropec- 

 ten Jiempricldi is referred to by v. Martens ['69, p. 131]. It is also mention- 

 ed from the Red Sea and the Gidf of Suez by Gray ['72, p. 119]. The 

 latter's specimens belong to the British Museum. 



Peereer mentions Astv(ypecten scoparius in his " Revision," and it 

 appears from his references that Valenciennes' manuscript is in possession
