I shall add here a few 
observations on the gen¬ 
ital organs of Asterias 
grønlandica.

ias. The ovaries attain 
generally a length of ca. 
Vs of the arms’ length;

The testes are, on the contrary, much branched organs and

In the ovaries eggs in all stages are found, but always so that

The efferent duets of the gonads present some features of in-

outwards through the body wall, ending on a little papilla, which 
is to be found on the side of the arm a short distance from the 
interradial line on the oral side (Fig. 3). The duet has ciliated
