 Hartlaub's specimen from Cochin China appears to represent a different 

 species from that represented by examples from Singapore). 



Himerometra Jcraepelini A. H. Clark, Smiths. Misc. Coll. (Quart. Issue), vol. 50, 

 1907, p. 356 (listed); Proc. Biol. Soc. Washington, vol. 22, 1909, p. 7 (listed);

Himerometra sp. A. H. Clark, Notes from the Leyden Museum, vol. 33, 1911, 

 p. 182 (Moluccas; examination of the type of Carpenter's Actinometra robusti- 

 pinna shows it to be a Himerometra, questionably referable to H. crassipinna 

 from Singapore, i. e., H. martensi); Crinoids of the Indian Ocean, 1912, p. 117 

 (type of Carpenter's Actinometra robustipinna a typical Himerometra, possibly 

 H. crassipinna). 



Himerometra sp. A. H. Clark, Smiths. Misc. Coll., vol. 60, 1912, No. 10, p. 18 

 (examination of the type of Hartlaub's Antedon kraepelini shows that it is a 

 true Himerometra; it appears to be a small specimen of H. robustipinna 

 A. H. Clark). 



Himerometra pulcher A. H. Clark, Crinoids of the Indian Ocean, 1912, p. 114 (new 

 name for Himerometra robustipinna A. H. Clark, 1908, not Actinometra robusti-

 13-36 fathoms, the depth given on the label attached to the specimen). 



Range. — Known from Akyab on the Arrakan Coast, Burma, the 

 Sunda Islands, the Moluccas, Amboina, south of San Gasanga 

 (Sanga Sanga) (Tataan group), Philippme Islands, and from Maccles-

No. 1, p. 32 (but not figs. 1, 5, 10, on pi. 1) (specimen from Cochin China;
