about of the same size. The following pinnules are small. The distal 

 pinnules are very slender, 8 mm. long with twenty segments. The 

 enlarged lower pinnules are slender and flagellate, of the type seen in 

 typical flagellata. 



This form differs from typical flagellata much as Capillaster multi- 

 radiata var. coccodistoma differs from true C. midtiradiata. It is 

 smaller and more delicate, with fewer arms, and lacks the charac- 

 teristic rugosity of the arm bases and the prominent synarthrial 

 tubercles. P 2 and P 3 are proportionately less enlarged and more 

 delicate, and are not greatly longer than Pj.

I. Gimsah Bay, African coast of the Gulf of Sue.-;; Dr. R. Hart- 

 meycr. — One fine specimen with twenty-nine arms 120 mm. long and

1. Tonga and Fiji. — Two small specimens. 



2. No Locality. — Two specimens ; the larger has the centrodorsal 

 broad, thin discoidal, the cirrus sockets arranged in two irregular 

 rows ; the bare dorsal pole is 4.5 mm. in diameter ; the cirri are about 

 XXXVII, 22-28 (usually nearer the latter), 20 mm. to 23 mm. long; 

 the forty arms are 20 mm. to 23 mm. long ; P, has about thirty seg- 

 ments and is about 17 mm. long, moderately slender; it is greatly 

 enlarged on the outside of the rays and nearly as much so on the inner- 

 most side of the IIBr series ; the segments in the outer half of the cirri 

 have a low sharp narrow median carination ; the smaller specimen had 

 probably between twenty-five and thirty arms; P 2 is slightly more 

 slender than usual, resembling that in the other individual ; the cirri 

 have 22-23 segments.
