Genus BASSIA L. Agassiz. 



BASSIA BASSENSIS (Quoy and Gaimard) Bigelow. 



Diphyes bassensis Quoy and Gaimard, 1834, p. 91, pi. 7, figs. 18-20. Syno- 

 nymy, Bigelow, 19116, p. 229. 



Bassia bassensis — material examined. 



All of the specimens were very much battered, but owing to its 

 characteristic form, and especially to the opacity of its ridges, which 

 appear white against a black background after preservation in for- 

 malin, bassensis is easily recognized. It was taken by the Siboga 

 in considerable numbers in Malayan waters. 



Genus GALEOLARIA Blainville. 



GALEOLARIA QUADRIVALIS Blainville. 



sulculeolaria quadrivalvis Blainville, 1830, p. 126. Synonymy, Bigelow, 

 1911 o, p. 137, pi. 5, figs. 1-7, 1918, p. 416. 



Galeolaria quadrivalvis — material examined. 



None of the specimens are in good condition : all have lost the en- 

 tire stem. 



It is somewhat surprising that no superior nectophores were found 

 among the numerous Galeolarias from station 5669, especially since 

 the long somatocyst is a good field mark for quadrivalvis, even when 

 the margin is so contracted that it is hard to distinguish the two nar- 

 row dorsal teeth. The inferior nectophores all show the characteris- 

 tic conditions of the nectosac. 



G. quadrivalvis was taken by the Siboga at 8 stations. It is widely 

 distributed over the eastern tropical Pacific, as well as in the Atlantic.
