This species was taken at Stations 4635, 4651, 4657, 4659, 4663, 4665, 

 4667, 4676, 4743, 4841, both at the surface and in open hauls from 300 fathoms 

 to the surface. It is represented by three very well-preserved entire colonies, 

 fourteen loose anterior, and six loose posterior nectophores. The largest an- 

 terior bell is 18 mm. the largest posterior one 19 mm. long. The three entire 

 specimens were captured while floating fully extended on the surface; and are 

 in an excellent state of preservation; and I have been able to compare them 

 with excellent material from the Bay of Naples. The canals of both nectophores 

 follow the course described for them by Gegenbaur, differing correspondingly 

 from those of the Diphyopsiinae. 



G. quadrivalvis has been so well described and figured by Vogt ('54) and by 

 Gegenbaur ('54) that a detailed account is unnecessary. I need only note that 

 in the conformation of the ba.se of the nectophores, and in the double constric- 

 tion of the posterior one, the present specimens are entirely typical. The diag- 

 nostic features of the species are enumerated in the key (p. 236); and this, 

 together with the photographs (Plate 6, figs. 1-3) may serve for identification. 



The only previous records of G. quadrivalvis from the Indo-Pacific region are 

 those of the "Siboga" specimens (Lens and Van Riemsdijk, :08), which agreed 

 perfectly with Mediterranean specimens; and Bedot's ('96, p. 370) statement 

 that it is ''abondante a Amboine, et les exemplaires que nous avons observes 

 etaient absolument semblables a ceux de la Mediterrannee." Huxley's G. 

 filiformis is doubtfully classed here by Lens and Van Riemsdijk, but it 

 probably belongs to G. australis.
