Chuniphyes multidentata — material examined. 



This interesting species is now fairly well known, thanks to the col- 

 lections made by the Siboga, by the Albatross in the eastern Pacific, 

 and by Doctor Fowler in the Bay of Biscay. One of the present supe- 

 rior nectophores is hopelessly crumpled, but the other is in good enough 

 condition to show that it is a perfectly typical example. The median 

 dilation of the somatocyst, which is apparently so constant that it 

 may fairly be called characteristic of the species, is crescentic — that 

 is, prolonged transversely on each side as a horn, just as it was in 

 four of the Biscayan specimens (Bigelow, 1911#). 



The occurrence of an example of this type in the Philippines is 

 especially interesting, because it shows that, as I supposed, the differ- 

 ence between crescentic, and spherical as seen in one Pacific example, 

 is merely a case of individual variation, or the result of contraction, 

 not evidence of two local races. 



The much crumpled inferior nectophore agrees very well with 

 the corresponding one described from the eastern Pacific (Bigelow, 

 19116). 



All previous records of Chuniphyes are from intermediate or clos- 

 ing-net hauls. It has never been taken on the surface. Unfortu- 

 nately no information is available as to the level from which the 

 Philippine specimens came. 



Family UNCERTAIN. 



ARCHISOMA NATANS Bigelow. 



Archisoma natans Bigelow, 1911&, p. 266, pi. 20, fig. 6. 



Station 5659 Gulf of Boni, Celebes ; 1 specimen in very good con- 

 dition except for the tentilla, which are all fragmentary; bract, 

 43 mm. long ; special nectophore, 24 mm. with three very young gono- 

 phores, and one older but damaged one (Cat. No. 29396, U.S.N.M.). 



The capture of an excellent example of this remarkable eudoxid 

 was timely, for it allows me to substantiate the main features of my 

 previous account and to add to it in some particulars.
