189 
outer ramus represented by 1 or 2 bristles. Mandible reduced to a stylet-sbaped 2-pronged blade; 
maxillae and anterior maxillipeds also strongly reduced. Posterior maxilliped 2-jointed, delicate, 
elongated, with short terminal hoolss. Feet with long, slender rami, of which inner are longer; the 
inner rami of all of the pairs and outer rami of second to fourth pairs 3-joiuted ; outer ramus of first pair 
1-jointed; fifth pair of feet rudimental, 2-jointed. 
Male: Differs from female in structure of abdomen (with 6 segments; furcal bristles sometimes 
elongated), also in structure of anterior antennae (grasping organs; joints of same number as in the 
female, but differing in relative lengths; articulation proximal to terminal joint), and posterior 
maxillipeds (longer than those of the female, second joint stouter, terminal hooks longer). 
25. Miracia efferata Dana; a , ovigerous female, from left side; b, male, dor- 
sal aspect; c, fifth foot, of ovigerous female; d, male, fifth foot. 
26. Glytemnestra rostrata Brady ; 
male ; a, dorsal aspect ; 6, fifth foot. 
26. Clytemnestra rostrata Brady. 
Furca at most as long as broad, bristles not plumose, alike in both sexes. Anterior antennae 
7 -jointed in both sexes; last joint in female 5 times as long as penultimate; no lancet-shaped thorn 
on antepenultimate joint in male. Outer ramus of posterior antennae represented by a single bristle; 
second basal joint of first foot without an outer marginal bristle, outer ramus of same with 3 bristles, 
outer ramus of second foot with 1, 1, 2 outer marginal bristles; second joint of inner ramus of third 
loot longer than third joint. Fifth foot as long as outer ramus of fourth foot, its terminal joint with 
5 bristles, which are of same length in male and female. 
Coloration: Reddish, owing to distribution through the whole transparent body of numerous 
pale rose-colored, pale ferruginous-brown or even light-green oil-globules. Eye, deep carmine-red; 
ovaries dark gray with a reddish tinge. 
Length of female, 1 mm. ; of male, 0.87 mm. 
A few male specimens of this species were collected in the Gulf Stream tow, about 60 miles south 
of Marthas Vineyard, July 28 and 29, late in the afternoon.
