Th imen from Stat. 274 has mis iio mm. long; there are four IIIBr series 



nt, three interna! and «me external, paired with one of the internat; the < irri are Wil. 

 mm. long; the longest cirrus segments are about a third again as long as broad, 

 rhe example trom Stat. 282 has 20 arms. 

 liit- individual trom Stat. 285 is ver) small with 10 arms. 



Of the four from Stat. 294 the largesl has 1 | arms 35 mm. long; all of the IIBr 

 ther has 11 arms 35 mm long; the single IIBr series is 4 (3 + 4); 

 the other two have n 1 arms 



Th imen trom Stat. 299 has [9 arms 80 mm. long; there are no IIIBr series-, 



the cirri are Wil. 1 15 mm. long. 



the two from Banda the larger has aboul 26 arms about 105 mm. long; three of 

 nes are 2; the IIIBr series are 3 (2 -f- 3); the cirri are XV, 24 — 26, 22 mm. tO 

 mm. Ion-, 



rhe very tïne example from the reef at Haingsisi has 20 arms [40 mm. long; all ot 

 the IIBr series are present, and all are 4 . the cirri are XIII, 20— 21, 15 mm. long; 



the longest cirrus segments are not more than one third again as long as broad; the anima! 

 i> verj robust: the brachials are very short with strongly produced distal edges. 



From the coral reef at Noimini Stat. 296) there is a small specimen with 15 arms; 

 of the IIBr series is 2. 



Dr. Reichensperger has recently described, under the name of Capillaster clarki, a 



of this genus from the Aru Islands based upon two specimens dredged l>y Dr. 



near 1'ulu Bambu in 10 metres: the cirri of the supposed new form are XXVIII — 



XXXIV, 20—21, 15 mm. long, stout, the longest segments (fifth-seventh ) slightly longcr than 



broad; the arms are 27 — 35, 85 mm. to [OO mm. long. 



The essential character of Capillaster clarki is the shortness of the proximal cirrus 



lents. The numerous specimens from the Aru Islands in the "Siboga" collection are for 



the most part characterized by rather unusually short cirrus segments, but as a similar shor- 



tening ot the longer proximal cirrus segments is not infrequent in examples of the species 



trom other localities I de not believe that C. clarki can be maintained as a separate form. 



The smaller ot Dr. Reichensperger 's two specimens has highly irregular division series, 

 as in tin- type of C, mariae. Hut this same extraordinary irregularity is occasionally found in 

 imens of C. multiradiala, and, rather more commonly, in the large species of 

 the alli' - Nemaster which represents Capillaster in the Atlantic 



Th- trmed young of this species may be distinguished from those of the species of 



mianthus by the long and slender cirri with a slight distal taper which, as 



commonly found, are nearly or quite straight. The cirri of the young of the species of Comaster 



and Coma nt lm shorter with fewer segments, and the .listal half is always strongly 



irved.
