S. I. Smith — Crustaceans of the Atlantic Coast. 
mens the terminal spines were invariably (as doubtfully described by 
Kriiyer) six in number, the median pair slender and ciliated, the sub- 
median very long and slender, and the outer short, as usual. 
None of the females examined ai*e carrying eggs. The males are 
scarcely perceptibly more slender than the females. The sexual 
characters are well-marked, in the antennulae and abdominal append- 
ages, in specimens 30 mm long, although in specimens 26 mm long the 
secondary appendage peculiar to the male is only just making its 
appearance on the inner lamella of the second pair of abdominal 
appendages.
