4. Singapore; Herr Jagor; Cat. No. 2456. — One small specimen 

 with 27 arms about 70 mm. long. It is rather poorly preserved so 

 that the large size of the outer pinnules is difficult to appreciate. 

 The outer 10 or 11 cirrus segments have small sharp median tubercles. 

 The very small size of P^ and the great difference in size between Pj 

 and the two adjacent pinnules show that this individual belongs to 

 D. protectus and not to D. palmata, under which name it was recorded 

 by Hartlaub. (See Die Comatulidenfauna des Indischen Ai-chipels, 

 p. 51.) 



5. Bougainville Island, Solomon Group; Gazelle. — Two specimens. 

 (See Zool. Anzeiger, vol. 34, No. 11/12, p. 367.) 



6. Salawatti; Oazelle. — Two specimens. (See Zool. Anzeiger, vol. 

 34, No. 11/12, p. 367.) 



7. No locality; Cat. No. 5334. — One specimen. 



DICHROMETRA TENERA (Hartlaub). 

 [For the synonymy, see The Crinoids of the Indian Ocean.] 



1. Western Australia. — Three specimens. (See Die Fauna Siid- 

 west-Australiens, vol. 3, Lief. 13, p. 460.) 



DICHROMETRA FLAGELLATA (J. MuUer). 

 (For the synonymy, see Notes from the Leyden Museum, vol. 33, p. 184.] 



1. Singapore; Prof. J. Miiller; Cat. No. 1282. — One specimen. 



DICHROMETRA PALMATA (J. MiUler). 

 [For the synonymy, see Proc. U. S. Nat. Mus., vol. 40, p. 27.] 



1. Um-el-Terman, Gulf of Suez; Dr. R. Hartmeyer; Cat. No. 

 5604. — One specimen. 



The centrodorsal is thick discoidal with a flat dorsal pole 2.5 mm. 

 in diameter; the cirrus sockets are arranged in two irregular closely 

 crowded rows. 



The cirri are XIV, 24-25 (usually the former), 20 mm. long; the 

 longer proximal segments are about one- third longer than broad; 

 the outer 8 or 10 segments are slightly broader than long and bear a 

 well-marked median dorsal keel which on the outermost shortens 

 into a small tubercle. 



There are 30 arms 115 mm. long; the division series are weU 

 rounded dorsally and well separated laterally; the arms are perfectly 

 smooth dorsally. 



Pi is 13 mm. long with 28 segments; it tapers rather rapidly for the 

 first four segments, then becoming more slender and tapering gradually 

 to the tip; the first segment is about twice as broad as long, the fol- 

 lowing gradually increasing in length so that the fourth is about as 

 long as broad, the segments beyond the seventh about one- third 

 again as long as broad, and the terminal half again as long as broad; 

 the first three segments have their distal angles slightly cut away, but
