PATTERN OF BUDDING 34» 



give at all an adequate idea of the complicated sequence, which is three-dimensional. At any rate I 

 failed to understand the later parts of his account. 



Moser (1925), who had sixty specimens of Physalia taken by the 'Gauss' expedition to deal with, 

 said that she had wanted to find an answer to the question whether certain alleged differences in origin 

 and arrangement of the groups of appendages described by Steche had the significance given to them 

 by him, or whether they were the expression of unending variation. But she had to confess that their 

 study was so irksome and time-consuming that finally, without coming to any conclusion, she had 

 contented herself with confirming the fact that there was great variation, and only exceptionally was 

 there the regularity of arrangement found by Steche. I, like Steche, found a regular pattern of 

 arrangement.

In 1932 Okada repeated Steche's scheme of diagrammatic representation of the arrangement of 

 cormidia, again with little success. Okada, who must have seen more of the very early developmental 

 stages than anyone before him, said (1935) that a fairly large number occurred in the plankton taken 

 at the Sete Marine Laboratory of Kyoto University in the spring of 1934, and that by comparing 

 them with one another he could deduce the order in which the polyps and tentacles were budded. 

 Unfortunately he did not enlarge on the subject in his short communication. The figures b, c and d of 

 his fig. 1 are all labelled to show that gastrozooid number 1, the earliest to appear, lies on the oral side 

 of the main tentacle, and gastrozooid number 2 on the oral side again of number 1 . Okada's figures c 

 and d both show gastrozooid number 3 on the aboral side of the main tentacle. In his 1932 paper 

 Okada had indicated the same order of appearance, based on the degree of development of gastrozooids 

 in a young specimen whose float-length was 2-5 mm. In addition, he indicated that gastrozooid 

 number 4 appeared aborally to number 3, and that number 5 appeared between numbers 1 and 2.
