The geniculation varies in different parts of the colony and 
may be absent in some regions. The colonies from Coronado are 
unusually low, and branched. Otherwise they are not distinguish- 
able from the typical forms. 
Gen. Clytia, Lamouroux, 1816. 
20. Clytia bakeri, n. sp. 
Trophosome. Stems clustered, about 20 mm. long, without branches. 
Each stem free, for 2 to 5 mm., from pedicels of hydrothecae, which then 
follow each other alternately in quick succession; closely annulated at base, 
annulae increasing gradually in length, ultimately becoming internodes of 
stem. Stem internodes usually 3 to 4 times as long as broad, each bearing 
a pedicel on a shoulder process from distal end. Hydrotheecae small, con- 
ical, without marginal teeth; pedicel consisting usually of but one annula 
almost as long as broad. 
Gonosome. Gonangia long, narrow, with bottlenose apertures, taper- 
ing gradually to short peduncies; borne usually in pairs at the bases of 
hydrothecal pedicels. Sporosacs abundant, 12 to 20.
