ing beyond the tips of the maxillipeds ; the ischium and merus are 

 practically subequal, elongate, the distal end of the merus reaching to 

 the base of the second peduncular article of the antennae ; the carpus 

 consists of ten elongate articles and extends to the tip of the maxilli- 

 ped; the propodus is weak, about twice as long as the distal carpal 

 article, the palm being one-half of this length, the fingers tapering, 

 horn-tipped. 



The third legs are as long as the second, slender, monodactyl, with 

 an acuminate, rather short, slightly curved dactyl ; the inferior lateral 

 margin of the propodus is set with a series of spine-like stiff setae. 

 The fourth and fifth legs are like the second but are successively 

 shorter.

 Zostera, in which the animal lives. 



Material examined : Seven specimens, two of which are large fe- 

 males, each carrying about 300 to 400 oval eggs, from Double-Headed 

 Shot Cay, Cay Sal Bank, Bahamas, February 19, 1925, 5i/^ fms. ; 

 grassy bottom. In the more developed groups of eggs, the eye-spots 

 and dorsal keel-spine are visible. 



Technical description : Animal very attenuated, * ' humped ' ' or bent 

 downward from the third segment posteriorly. Rostrum dagger-like, 

 a couple of millimeters longer than the carapace, directed straight for- 

 ward, tapering to a very acuminate point distally ; the dorsal surface 

 is moderately convex and thickened; the ventral surface is produced 

 into a thin laminate keel, which extends from the apex to just anterior 

 of the cornea where it is widest ; the entire lower margin is serrulate, 

 with 10 to 18 sharp little teeth between which are fine cilia.
