d) Carotenoids in Worms 



Carotenoids in worms have recently been investigated, particularly by 

 LoNNBERG and by Lonnberg and Hellstrom. x\lthough these studies are 

 mainly based on spectroscopic data, it appears very probable that carotene 

 and xanthophyll occur in worms. The red carotenoids with the single absorption 

 band previously reported by Krukenberg were not observed by the first- 

 named authois. The following is a summary of carotenoids in worms which 

 has been mostly taken from the dissertation of Walker (Ref. 18, p. 108) and 

 brought up to date.
