This form is similar in general characters and distribution to the pre- 

 ceding. The accompanying figure, after Mayer, gives an idea of its general 

 shape and size. Chun regards it as an extremely variable species, both in 

 the size and proportions of the colony. It is frequently taken in the 

 deeper tows, particularly south of Marthas Vineyard and in the region of 

 Nantucket.

This is a large siphonophore, of a generally boreal habitat. The descrip- 

 tion of Agassiz (vide supra) is quite full, with good figures, including also 

 accounts of its development, which obviates the necessity of fuller details 

 here.

Occasionally taken within the region adjacent to the Gulf Stream, but 

 Diphyopsis campanulifera. rarely, if at all, near to the coast. 

 After Mayer. 



ANTHOPHYSA Mertens (1829). 



Anthophysa formosa ( Fewkes) . 



Athorybiaformosa Fewkes, Bulletin Museum Comparative Zoology, Vol. IX, 18S2, p. 271. 

 Anthophysa formosa Chun, Die Siphonophoren der Plankton-Expedition, 1898, p. 61. 



This species was first described by Fewkes from the Tortugas, and has not since been recorded out 

 of that general region till reported by Chun (vide supra). Hseckel has described under the name of 

 Anthophysa darwinii what is apparently the same species. 



During the summer of 1902 a single specimen of this interesting siphonophore was taken south of 

 Marthas Vineyard. It agrees in general characters with the descriptions of both Fewkes and Chun. 

 In size it is intermediate between the specimens they described, being about 4 nun. in diameter, and 

 about the same in height.
