Text-fig. 1 6. Physalia physalis. The cormidia of the main zone of a well-preserved, young, right-handed specimen K.2, 

 float-length n mm., taken by Miss Dodge near Miami, to show the pattern of budding. A = cormidium I, B = cormi- 

 dium II, C = cormidia III-VII. Group i of cormidium I is atypical in having lateral (ij and basal (i B ) buds. The arrange- 

 ment of the parts for this drawing differs slightly from that in the specimen as photographed in PI. VIII, fig. 5. x 20. (From 

 below, see Text-fig. 21 e.) 



of cormidium VII, at the oral end of the cormidium. These secondary branches form a regular pattern 

 and consist of later developed tripartite groups of appendages (Text-fig. 12). To leeward (PI. XV, 

 fig. 3) they arise from the base of the second group, which becomes incorporated into the ventral 

 wall of each cormidial section of the float ; aborally (PI. XVI, fig. 3) they can spring from the peduncles 

 of the fourth lateral group et seq. The branch at the oral end, when present, springs from the base 

 of the gonodendron of the first group.
