specimens observed the young ones are all in very nearly the same 
stage of development, evidently just ready to leave the mother, 
made me think that possibly the eggs might develop within the 
stomach or in a special brood pouch, as is the case in Granaster 
nutrix Studer and in Leptasterias groenlandica (Steenstr.). I did, 
however, not observe anything to support this suggestion in the 
several specimens which I opened. — It would be very interest- 
ing to know, whether Calvasterias Suteri protects its brood in the 
same way. That it has not typical pelagic larvæ, as suggested by 
Kochler (Op. cit. p. 88), has been made fairly evident by Fisher 
(Notes on Asteroidea. Ann. Nat. Hist. 9. Ser. X, p. 597), who found 
its eggs to be of the large, yolky type. As my own alkoholic 
specimens happen to be males I can give no new evidences as to 
this point. 
A small specimen of this species is found in the collection of 
the Copenhagen Museum, which was received, unidentified, from 
the Paris Museum, 1877. This proves that the species was found 
there already by Filhol, though not mentioned in his report.

Several specimens were collected on the rocks, at low tide, at 
Cape Maria van Diemen; 4/1. 1915. They were found attached in 
all sorts of crevices in the rocks, attaching themselves so strongly 
that they were torn to pieces, if one tried to detach them without 
the aid of a knife — as already stated by Farquhar (1895). 
Evidently, they are especially adopted to living on rocks exposed 
to a violent surf. They were found to feed on the mussels (Mytilus)
