For the lengths of individual paralleled in the San Diego 

 material, the length of ovary corresponds as closely as one would 

 expect, but as most of our specimens are very much larger an 

 exact comparison is impossible. (Compare also the measure- 

 ments recorded by Ritter-Zahony, 1910, pp. 265-6 for /S'.

Measurements concerning the Ovary in Sagitta planltonis. 



Ocary approaching maturity 



1 Measured in per cent of total length of animal. 



2 Measured in per cent of total length of ovary. 



As in the case of S. lyra, none of the specimens examined 

 appeared to be fully mature. Nos. 2 and 3 (pi. 5, fig. 12) 

 approximate most nearly to complete maturity, which fact would 

 indicate that the mature ovary extends nearly to the ventral 

 ganglion.
