FISHERY BULLETIN: VOL. 83, NO. 3 



revision by Kuris and Carlton (1977), with one excep- 

 tion. I use only Crangon, rather than Crangon and 

 Neocrangon, because I agree with Butler (1980) and

 Crangon into two subgenera, Crangon s.s. and 

 Neocrangon, to be invalid. 



The synopsis of characters of Crangon septem- 

 spinosa larvae also applies to the characters of C. af- 

 finis larvae. Needier (1941), Kurata (1964b), and 

 Tesmer and Broad (1964) have described these as 

 two species, but according to Makarov (1967), the 

 two species are synonymous. Descriptions of the lar-
