This oeing so we conclude that tne four last spec- 

 imens were a little younger than tne three first 

 ones,and that this explains tne proportionally shon 

 er lengtn of tne lateral horns, with wnicn tney were 

 anchored in tne fish's musele,and tnat tne horns in 

 time would oecome proportionally longer. This 

 could not "be an accident since tne individual va- 

 riation in tnis proportion was almost unnoticeaole. 

 Tne egg st rings always ended in a claw-lilce poin 

 slcetcned and descrilDed toy Nordmann and were always 

 oent in a half circle. 



Next after tne relation of tne norne we are ae- 

 customed to use for tne separation of tne species 

 tne unftrancned or orancned condition of tne plumule 

 on tne aftdomen. Long ago ( 175*0 Linnaeus gave 

 as tne character i sti es of his P.sagitta that these 

 plumules were simple, and tnis has also oeen repeate 

 "by later invest igators (M.Edwards, etc. ) • 



But tnis statement is a very long ways from sayir 

 that they have some common entity,and we may assume 

 that Linnaeus did not say tnis in eomparisonm with 

 otner Pennellas,out only in comparison with the so 

 def initely oranched plumules of the polyps(Pennat- 

 ulae) with which he then,as well as later , through 



lacK of tetter Knowledge placed his P.sagitta
