epithelium on its inside. Generally there is only one papilla, but 
sometimes two papillæ may be found to each gonad and some- 
times two duets were found in the same papilla. The genital 
papilla is found both in male and female specimens. This holds 
good also for Asterias Miilleri. 
One of the specimens of Asterias grønlandica presented the in- 
teresting case of an hermaphroditic gonad. 
While nine of the gonads were purely female, the tenth was 
apparently a purely male gonad. A doser examination, however, 
showed it to be hermaphroditic in the tip of the gonad. 
In Fig. 4 is represented a section through the hermaphroditic 
part of this gonad, showing the hermaphroditic character very dis¬ 
ti netly, the eggs lying along the wall and the spermatozoa in the 
midale. 
As hermaphroditism appears to be of very rare occurrence in 
Asteroids (besides the protandric hermaphrodite Asterina gibbosa, 1 ) 
similar cases were found only in Asterias glacialis-) and Asterias 
rubens 3 )) I have thought this case of hermaphroditism in Asterias 
grønlandica well worth mentioning.
