shows faint indications of segmentation at the anterior end of the trunk. 
The first somite by means of a lateral protuberance forms a point of attach¬ 
ment for the male, and will be referred to as the “shoulder,” the male’s 
second maxillae being anterior to the protuberance, the maxillipedes posterior 
to it (Fig. 1). 
Although it is generally agreed that a single pair of spermatophores 
contain sufficient spermatozoa to fertilize all the eggs a female can lay during 
3mm,

her lifetime, yet the male may remain clinging to her shoulder for a short 
period after mating (which takes place upon reaching maturity immediately 
after the moult at the close of the second copepod stage), since all my 
specimens of females were provided with well developed, normal egg-strings. 
It is unlikely, however that the male lives very long after fastening the first 
pair of spermatophores in place in the spermathecae of the female, judging 
from rarity of males in this and other species.
