GYMNOBLASTEA 



Family tubularid^e 



Tubularia crocea (Agassiz) 



Parypha crocea Agassiz, Cont. Nat. Hist., U.S., vol. IV, 1862, p. 249. 

 Tubularia crocea Fraser, West Coast Hydroids, 1911, p. 27. 



There were but two specimens of this species, one growing on a 

 colony of Bryozoa and the other on Abietinaria. The one was a 

 young specimen and of itself would not have been sufficiently devel- 

 oped for diagnosis as it had but 8 proximal and 8 distal tentacles, but 

 it bore sufficient resemblance to the other to leave little doubt that 

 it belonged to the same species. The second one was much farther 

 advanced ; but there was no sign of a stolon starting or of any but the 

 one zooid in the colony.
