The forty-one specimens range in diameter from 1-8 mm.; and are all 

 fairly well preserved. The variability in the form of the somatocyst has already 

 been noted. In several examples the groups of appendages were sufficiently 

 far advanced to show the typical "Diplophysa" form of bract so often de- 

 scribed, and so far as these young stages show there is no visible difference in 

 this structure between Atlantic and Pacific specimens. The various records 

 show that S. truncata occurs generally over the tropical and subtropical regions 

 of all three great oceans. 



Muggiinae, nom. nov. 



Cymhonedidae Haeckel, '88a, '88b; Chun, '88, '92. 



The name Cymboncetidae must be abandoned because as Chun ('92) and 

 Schneider ('98) point out Cymbonectes Haeckel is undoubtedly identical with 

 Muggiaea Busch. To replace it I suggest Muggiinae. At present three genera 

 can be distinguished: Muggiaea and Doromasia, both of Diphyid outline, but 

 separated by the presence of a special nectophore in the latter, contrasted with 

 its absence in the former, and Cuboides ( = Halopyramis) easily distinguished 

 by its peculiar pyramidal shape (p. 189). Schneider unites Doromasia and 

 Muggiaea, but the difference above mentioned seems as worthy of generic 

 recognition here as among the Diphyidae. It is possible, however, that Doro- 

 masia will finally be abandoned on another ground, namely that it is not a 

 Sphaeronectid but a Diphyid (p. 265). 



MUGGIAEA Busch 1851. 



Four species have been described which must be referred to Muggiaea, 

 as above defined, viz. M. kochii (Will) Chun ( = M. pyramidalis, Busch 

 = Monophyes primordialis Chun), M. pyramidalis Haeckel, M. (Cybonectes)
