In the small Challenger specimen from near Kandavu, Fiji, the arms, according 

 to Carpenter, are shorter and less fleshy than in LoveVs specimens from New Har- 

 bour, with less spiny brachials, the terminal faces of which are less closely applied. 

 The basal pinnules are relatively shorter and their component segments less spiny, 

 while the segments of the terminal pinnules are almost smooth and the pinnules 

 stiffer, so that the arms have a less feathery appearance. 



On the other hand, a specimen from Fiji obtained from the Godeffroy Museum 

 (presumably the one in the Hamburg Museum) and recorded by Carpenter has 

 moderately feathery arms and more spiny pinnules. 



The small specimen from Fiji in the Copenhagen Museum bearing Liitken's 

 manuscript name stellatus has nearly 80 arms, which are 80 mm. long. There are 

 6 or 7 postradial axillaries. Eight of the 10 IIBr series are 2 (1 +2), the remaining 

 2 being 4 (3 + 4). The distal division series which are developed out of the regular 

 order as described below, 3 in number, are 4 (3 + 4), the remainder being 2 (1+2). 

 The first syzygy on the undivided arms is between brachials 1 + 2. 



Each IIBr axillary bears externally an undivided arm and internally a IIIBr 

 2 (1+2) series. The latter bears a IVBr series and an undivided arm, which last is 

 on the opposite side from that arising from the axillary preceding. Subsequent arm 

 divisions are similar, the axillaries bearing each a division series of 2 (1 + 2) and an 

 undivided arm, the undivided arms being given off from alternate sides. The general 

 appearance, therefore, is that of two very stout arms arising from each IIBr axillary, 

 from which smaller arms arise on every alternate ossicle, being given off first on one 

 side and then on the other. 



Of the specimens from Port Galera, Mindoro, one (M. C. Z., 660) is a slender 

 example, with about 130 arms which are about 180 mm. long. Another (M. C. Z., 



662) is slender, with about 100 arms which are about 115 mm. long. A third (M. C. Z., 



663) is small, with about 100 arms which are about 85 mm. long. Of the remainder 

 (M. C. Z., 618), one has about 150 arms which are about 250 mm. long; one has 

 about 150 arms about 230 mm. long; one has about 100 arms 125 mm. long; two 

 have about 90 arms 125 mm. long; and the last has the arms intertwined dorsally 

 so as to conceal the division series. One specimen (M. C. Z., 661) is represented 

 by fragments. 



Carpenter said that some large specimens from Cebu which are preserved in 

 the zoological museums at Dresden and Vienna do not differ much from the type, 

 except that the lower pinnules decrease more gradually in size. 



Carpenter noted that in this species the centrodorsal is stellate, with little or 

 no trace of cirrus sockets, and is nearly flush with the radials, sometimes being even 

 below their level. It is separated from the radials by distinct clefts. 



He remarked that the articulation between the elements of the IBr series, as 

 illustrated by the Challenger specimen from Fiji, appeared to be a syzygy of much 

 the same character as that found in the_pentacrinites and in Rhizocrinus ; that is, 

 with the apposed faces almost smooth and devoid of the radial striation which is so 

 marked in the syzygies of Antedon. The result is that the junction line of the 2 ossi- 

 cles as viewed dorsally is simple instead of being more or less interrupted or dotted, 

 as it is in the case of the syzygies in the later division series. He said that Lov6n's
