As regards the granular bodies, Hertwig (doc. cit., p. 82, 
pl. viii., fig. 1) makes the following statement about Chiton- 
anthus pectinata, ‘in it (the mesoglea), there are small roundish 
concrements which are strongly coloured by carmine, and the 
structure of which recalls that of granules of starch; they are 
made up of indistinct concentric layers, frequently appear in 
section like a figure 8, and are limited to the superficial layer of 
the mesoderm.”’ He makes no conjecture as to their nature. 
It seems likely that the granular bodies found in Phellia 
Sollasi may be of the same nature as those in Chitonanthus pectinata ; 
they are not identical with them, as they are not in the least like 
the figure, and are not apparently made up of concentric layers, 
though a different method of preservation might make a difference 
in their appearance. The only other references to such structures 
that I can find are in M*Murrich (‘‘Albatross ” Report, Proc. U.S. 
Nat. Mus., 1893, p.177), where he describes “ granular, spherical, 
or oval bodies in the ectoderm of the dise of Sagartia lactea’”’; they 
stained deeply, and he believed them to be glandular ; he gives no 
figure, but the description, though not the situation, resembles the 
bodies in Phedlia Sollasi. 8. J. Hickson (Quart. Journ. Mier. Sci., 
vol. 37, pt. 4) describes and figures dark homogeneous bodies seen 
in and among strands of endoderm cells; in the mesoglea of 
Alcyonium, he thought they were probably parasitic sporozoon. 
I should be inclined to regard the bodies seen in Phedlia Sollasi 
as due to a parasite more likely vegetable than animal.

Through the kindness of Professor Haddon, I was given six 
specimens of this species to examine. 
External Characters.—These are described from the living 
animal by Andres, Le Attinie, 1884, p. 256. The specimens I 
examined were preserved in alcohol; the colour is lost. Size: 
height 30-40 mm.; average diameter of column 12-18 mm. 
One specimen is completely retracted. The shape of most of the 
specimens is cylindrical; one is urn-shaped.
