Campakulariidae: Either a branched or a simple colony on 

 which are campanulate and usually stalked hydrothecae; hypos- 

 tome trumpet-shaped. Gonangium large, never with free medusae.

 Littorale de Belgique. 1867, p. 163. 



This species I am not at all certain about but my specimens 

 seem to agree very well with descriptions and keys of both Nutting 

 and Torrey. If the identification should prove correct the species 

 has a much more southerly distribution than hitherto reported. 

 Calkins reports it from Puget Sound but Torrey has not included 

 it in his descriptions. The species is decidedly northern. 



The gonangia of my specimens are a little fuller and with more 

 pronounced opercula than that figured by Nutting, but as those of 

 my specimens are ripe and those figured by Nutting are not this 

 may be of little significance. 



Specimens on thalli of a seaweed, probably Macrocystis, exact 

 source unknown. Bottle labeled. Illingsworth, Pacific Grove, 

 July, 1899. Many ripe gonangia.
