CAMPANULARIIDAE: 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. 
Campanularia exigua (Sars) Van Beneden. Rec. sur Ja Faune 
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.
