" The actinal intermediate phites are aiTaugecl in chevrons and decrease 

 in size toward the margin. Thoy are polygonal, and covered with a 

 coai-ser gi-aniüation than the dorsal plates — a granulation which increases 

 somewhat in coai-seness toward the centre of each slightly convex plate, 

 A\hich is surrounded by 1 to 5 enlarged granules, usually of unequal size. 

 Scattered here and there are bivalved x^f^clicellarise, 0.25 to 0.75 mm. in 

 length. 



"The furrow spinelets are 4 to 5 in number, robust, short, truncate, 

 slightly flattened, the adorai spinelet sliorter than the others. On the 

 a^tinal sm'face of the plate stands a longitudinal series of 2 or 3 shorter, 

 thicker, gi'anuliferous spinelets, Avith often 1 to 2 smaller granules standing 

 in line at either end of the series. Occasionally' a very small bivalved 

 pedicellaria stands at the adorai end of the series out of line. Behind the 

 actinal series the fine granulation of the general sm-face begins, decreasing 

 in size toward outer end of plate. The fm-row spinelets appear a trifle 

 slioiier and heavier than those figured by de Loriol. A few of the j^i'ox- 

 imal adambulacral x)lates have 6 furrow spinelets. 



" This species has a wide range, being found in following localities : 

 Ked Sea, Moluccas, New Guinea [Müller and Troschel], Mauritius, 

 Macassar (Celebes), Fiji Islands [de Loriol], Ceylon, Madagascar, 'East- 

 em Archipelago ' [Sladen]. Its capture in the Hawaiian Islands consider- 

 ably extends its known range." 



The following notes on this species by Clark is important as pointing 

 out clearh- for tlie first time that the starfish Goniodiscus sebœ is a voung 

 foi-m of C. novœ-ijuincœ [Ciaf.k, : 08, p. 281]'^ : 



"3 specimens, 80-130 mm. in diameter. Sorong, New (ruinea. — 1 speci- 

 men, 75 mm. iu diameter. Amboina. Barbour collection. 



" The small series of Culcitas brought home b}- Mr. Barbour is of 

 gi'eat interest because they prove tliat the starfisli hitherto known as 

 Goniodisciis sebce is the young of CulcUa novœ-guineœ and not a distinct 

 S]^)ecies related to the ancestral stock from which Culcita has sprimg, as 

 Döderlein has so ably argued (Semon's Zool. Forsch. Aust., 5, If. 4, -p. 489
