JAPANESE ASTEROIDEA 489 



radius there are two such tubercles; eight on the ridge of each ray, with a 

 uinth on two of the rays ; the usual pair at the base of each ray ; and one , 

 two, or even three extra tubercles on the sides of the rays near the base. 

 No less than 20 of the tubercles terminate in two, three, or even four sharp, 

 bare points. — ^In life, the colour of this species shows considerable diversity, 

 ranging from clay-colour with the large tubsrcles muddy brown, or with the 

 large tubercles deep red-brown, becoming vermilion at the base, or with the 

 large tubercles black, with their bases, the tips of the arms, and the centre 

 of the disk claret-red, to a nearly uniform vermilion-red all over. Most of 

 tlie dried specimens were dirty yellowish, but on being washed with alcohol 

 the vermilion-red colour retm-ned to a greater or less degree in different 

 individuals and has not been lost by subsequent drying. The largest speci- 

 men (300 mm.) from Amboina is the most imiform and the brightest ver- 

 mihon.— This species was found chiefly on bottoms where there was more 

 or less vegetation or in open places about coral reefs." 



Under the name of Pentaceros turrlhis Linck Kœhler mentions this 

 starfish from the south-eastern Moluccas [:11, p. 277] : 



" Dragage No. 6. 28 Mars 1908. Sungi Manumbai. Profondem- 23 m. 

 Deux échantillons. 



"17 Avi'il 1908. Wokam. Profondeur 2 m. Un grand échantillons. 

 " 17 Juin 1908. Nuhu Tawim (iles Kei). Un grand échantillon. 

 "Dans I'uu des individus du dragage No. 6, chez lequel Pv = 95mm., les 

 tubercules sont coniques et pointus. Dans le second, qui est \An^ petit 

 (E, = 75mm.), ces tubercules sont arrondis au sommet. 



" Les deux grands échantillons offrent ime différence analogue : celui des 

 îles Kei, dans lequel R mesm-e 120 mm., a de gros tubercules arrondis, tandis 

 que chez l'autre, qui est plus grand (R — 140 mm.), ces tubercules sont co- 

 niques et pointus. 



" J'obser^^e dans les aires porifères de petits j)édicellaires alvéolaires 

 identiques à ceux que j'ai signalés chez P. rouxi, et qui se montrent surtout 

 sur les deux petits exemplaires." 



I have only one dried specimen of somewhat large size, r= 

 Simm., R = 144mm., giving the radial ratio 2.7. The body is
