in detail; ^ one of the other specimens has 18 arms about 90 mm. long; 

 six IIBr series are present, five 4(3 + 4) and one 2; one of the IIBr 

 4(3 + 4) series bears internally a IIIBr series; the IIBr 2 series bears a 

 IIIBr 4(3+4) series externally. The color of this specimen is pur- 

 ple. The third example has 13 arms 65 mm. long, the three IIBr 

 series bemg 4(3 + 4); the cirri are XVI, 32-33, 20 mm. long; the 

 color is brownish white, the cirri light purple. 



This species is easily distinguished from Amphimetra africana by 

 the tapering cirri which bear shorter dorsal spines, by the much 

 more slender lower pinnules, and by the longer wedge-shaped 

 brachials.

Himerometra magnipinna A. H. Clark, Smiths. Misc. Coll. (Quarterly Issue), 

 vol. 52, 1908, p. 214. 



1. St. Mathias Island; Herr H. Schode. — One fine specimen. 



HIMEROMETRA CRASSIPINNA (Hartlaub). 

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



1. British North Borneo; Herr Pagel; Cat. No. 4744. — One speci- 

 men, resembling others at hand from Smgapore, though the proximal 

 cirrus segments are a trifle shorter. 



2. Singapore; Prof. E. von Martens; Cat. No. 5373. — One speci- 

 men, which served Doctor Hartlaub as the type of his Antedon mar- 

 tensi. (See Die Comatulidenfauna des Indischen Archipels, p. 21, 

 pi. 1, figs. 3 and 6.) 



This is a rather small and badly broken specimen, but it agrees in 

 every particular with numerous specimens of H. crassipimia from 

 Singapore at hand belonging to the Copenhagen Museum. (See 

 Vidensk. Medd. fra den Naturhist. Forening i K0benhavn, 1909, 

 p. 155.) 



HETEROMETRA SAVIGNU (J. MUUer). 

 [For the synonymy, see Proc. U. S. Nat. Mus., vol. 40, p. 24.] 



1. Red Sea; Hempricht andEhrenberg; Cat. No. 1056. — One speci- 

 men, which was a part of Miiller's type material. The centrodorsal 

 is discoidal, moderately thick, with a flat dorsal pole 3 mm. in diame- 

 ter; the cirrus sockets are arranged in two and a partial third alter- 

 nating marginal rows. 



The cirri are about 20 mm. long with from 23 to 25 segments, but 

 the best developed cirri are all broken off; long and prominent dor- 

 sal spines are developed from the twelfth segment onward.
