The single example of Forskalia is in such poor condition that it is 

 hopeless to try to identify it specifically. But the younger nectophores 

 -are of the characteristic Forskalia. outline, as are the siphons.

Also many fragments from station 5489 [M.C.Z.., Cat. No. 175.7, and U.S.N.M., Cat. 

 No. 29421]. 



This widely distributed species, usually known either as Crystal- 

 lomia polygonata Dana, or as Crystallodes vitreus Haeckel, has been 

 described in detail by Haeckel (1869, 1888), by Lens and Van 

 Riemsdijk (1908), and by me in a previous paper (19115). 



The present series consists of fragments. Most of the records are 

 from detached nectophores and bracts. But these have such charac- 

 teristic forms that they are not likely to be misidentified. 



A. okeni is already known from Malayan waters (Lens and Van 

 Riemsdijk, 1908; Bedot, 1896); and is common and generally dis- 

 tributed in the tropical parts of the Pacific, as well as in the Atlantic 

 and Indian Oceans. And Moser (1915) now reports it from the 

 Mediterranean.

Station 5175 : Sulu Sea between Palawan and Negros ; 1 specimen, 

 8 mm. long, (Cat. No. 29376, U.S.N. M.). The stem is denuded, but 

 there are a few palpons and nectophores in the bottle. 



The characteristic dilation of the siphosome identifies this frag- 

 mentary specimen.
