PLATE VII 



Post-larvae of Physatia physalis collected by Miss Dodge 

 near Miami, Florida. 



Fig. i. Early stages showing the formation of cormidia II, III and VII 

 are seen in the lowermost two larvae (cf. Text-fig. 23 D). Cormidia 

 I and IV can be seen as buds in the top right specimen (cf. Text- 

 figs. 23 J and 24, A and B). x 7-3. 



Fig. 2. Two of the earliest stages of development of cormidia II, III 

 and VII (cf. Text-fig. 23 B, D, E and G). x 16 approx. 



Fig. 3. The lowermost specimen shows buds of cormidia I, II, III and 

 VII. The square-shaped bud is the ampulla of II group^ and is 

 separated by its tentacle from the gastrozooid of II groupj. The 

 uppermost specimen shows the extent of the pneumatocyst (cf. 

 Text-figs. 23 J and 24^ and B). x 11-4 approx. 



Fig. 4. The four buds seen clearly in the centre and lower right 

 specimens are those of gastrozooid II, ampulla II, gastrozooids 11^ 

 and VIIj (cf. Text-figs. 23^ and 24^} and B). x 73.
