requirements of the original description. A recent reexamination of 

 this individual has shown that it is undoubtedly referable to Himero- 

 metra lartschi, the long and rather slender cirri, the very long and 

 comparatively slender proximal pinnules which become very delicate 

 and flagellate distally, and the incipient carination of the lower 

 pinnules being sufficiently diagnostic. 



In 1911 Himerometra magnipinna was recorded from Palawan, in 

 the Philippine Islands, and, in a paper on the recent crinoids preserved 

 in the Leyden Museum, a redescription of the type specimen of Car- 

 penter's Adinometra rohustipinna which the author had recently 

 examined in Leyden was published. 



In a paper on the crinoids of the Hamburg Museum which appeared 

 in 1912 the type specimen of Antedon hraepelini was redescribed, and 

 Hartlaub's specimen from Cochin China, which he had referred to 

 his Antedon crassipinna, was redetermmed as identical with Himero- 

 metra magnipinnxi, the redetermination having been based upon a 

 direct comparison with the type of the latter. Himerometra magni- 

 pinna was also recorded from Isabela, on the island of Basilan, Phil- 

 ippines; Ekalin, on St. Mathias Island; and from Pitilu, in the 

 Admiralty Islands. In a paper on the crinoids of the Berlm Museum 

 published a few days later, the identity of the specimen described by 

 Hartlaub as Antedon mnrtensi with the specimens recorded from 

 Singapore under the name of Himerometra crassipinna was announced, 

 and both were referred to H. crassipinna as the true identification 

 of the types of that form had not at that time been determmed. 

 Himerometra crassipinna (i. e., H. martensi) was also recorded from 

 British North Borneo (the comparison being made with specimens 

 from Singapore), and H. m^ignipinna was recorded from St. Mathias 

 Island. 



In the present author's monograph of the crinoids of the Indian 

 Ocean the fu'st comprehensive survey of the genus Himerometra was 

 published. In this the following species are admitted as valid: 



Himerometra bartscM, Philippine Islands. 



Himerometra magnipinna, Philippine Islands; St. Mathias Island. 



Himerometra pulcher, new name {Himerometra robustipinna A. H. Clark, 



1908, not Actinometra robustipinna P. H. Carpenter, 1881), Phihppine 



Islands. 

 Himerometra inopinata, Macclesfield Bank. 

 Himerometra sol, Maldive Islands. 

 Himerometra crassipinna, Amboina; Singapore; Pulau Ubin, Singapore; 



?Cochin China. 

 Himerometra hraepelini, Akyab, Burma. 

 Himerometra persica, Persian Gulf; Philippine Islands. 

 Himerometra sp. {Actinometra robustipinna), Moluccas. 



Antedon martensi as in 1909 was referred to the genus Heterometra 

 instead of to the genus Himerometra.
