This species is usually known as Halopyramis adamantina Chun. 

 But as Chun (1892) himself says that its eudoxid is the Cuboides 

 vitreus of Quoy and Gaimard — a statement which is undoubtedly 

 correct — no choice is left but to use the older name for the species 

 as a whole. 



Like Bedot (1896) and Lens and Van Riemsdijk (1908), I have 

 been unable to find any differences to separate the Philippine or 

 Eastern Pacific from Atlantic specimens. Chun's beautiful figure 

 (1892) might have been taken from any one of the larger Philippine 

 specimens. Cuboides vitreus, like so many other siphonophores, 

 occurs in the warmer parts of all great oceans. 



The present specimens, in excellent condition, are larger than any 

 Indo-Pacific examples yet recorded, the nectophores measuring 9 to 

 14 mm., the bract of the eudoxid from 4 to 10 mm. in height.

Each of the specimens has lost the older bractlike nectophore, 

 besides the stem and appendages. But the outlines and proportions 

 of the nectosac of the remaining nectophores are so characteristic 

 that the identification is justified. 



The specimens are interesting chiefly because they extend the 

 range of genus and species to Philippine waters. It was known 

 previously only from the Atlantic and from the eastern tropical 

 Pacific.
