meats ; very many coarsely granular gland-cells are present in the filament- 

 endoderm, and the glandular parts of the filaments. Here and there one 

 sees a spirocyst, and appearances suggesting the tests of parasitic algae are 

 also to be found. The glandular filament-lobes are provided with numerous 

 thick-walled cnidae: they are fairly long, hardly narrow enough to be termed 

 aeedle-like. 



The acontia have quite a distinct appearance, in transverse sections, from 

 the filament- . ne ihin_ r . they always contain a much larger core of 



3 ea than the compound glandular filaments. Again, they have more 

 thick- walled nematocysts, which, in addition, are distinctly longer, narrower, 

 and more pointed at the outer end than those of the filaments. They also 

 have a special development of eosinophilous cells, which have the appearance 

 of bundles of small pink bubbles. There are also many elongate coarsely 

 granular gland-cells. 



i v) I have had doubts as to the wisdom of describing Chondrodactis pidchra 

 as a distinct se in many respects they resemble 



one anothei ably. In the end. however, 1 have decided to separate 



them, taking into account the Bum of small differences; these are, of course, 

 more readily apj omparative study of the specimens, but I hope 



the figures in PI. XVIII will show th.' difl which exist, for instance, 



between tin- parietal muscles and the tentacular muscles of the two. Our 

 knowledg n Actiniaria is hardly sufficient, so far, to 



how mil' species may show in the details of 



thai pending further light I prefer to consider these two as 

 distinct forms.
