 siphonoglyphos may have weak ectodermal muHcle.

Phy man thus is an easily idenlifiod genus, and interesting 

 as giving bints as to its evolution in the species which verge in 

 structure in the direction of H a 1 c a m p a . The genus C r a ni - 

 b a c t i s of Haeckel is invalid ; Carlgren states that the queer 

 inner tentacles were only extruded filaments (1900, p. 58). 



Family 9. Heteranthidae, Carlgr. 



Hclcranthidae, Carlgr., 1900, p. 72, 1900 (' Ofv. Vet.-Akad. 

 Forh.'), p. 27S.

pro parte. 



Endomyaria with definite base. The column in the only known form 

 has verrucae and fosse, the distal margin with little warted lobes ; the 

 sphincter is not very strong, endodermal circmuscribed" ; the tentacles 

 are distinctly marked off into marginal and discal, the marginal short 

 conical, the discal wart-like, in rows ; the mesenterial musculature is 

 well developed.

See above definition for chief characteristics. I know nothing 

 of this family save the details here given, which are taken from 

 Carlgren, 1900, p. 72.
