Leptochelia litnicola Harger. 



Paratanais limicola Harger, Am. Jour. Sci"., Ill, vol. xv, p. 378, 1878. 

 Leptovhelia limicola Harger, Proc. U. S. Nat. Mus., 1879, vol. ii, p. 163, 1879. 

 * Plate XIII, Figs. 87, 88. 



I have seeii only females of this species, and these in general much 

 resemble the same sex in L. algicola described above, but differ as fol- 

 lows : The eyes are small and inconspicuous, being' less than half the 

 transverse diameter of the basal antennular segment. The second seg- 

 ment of the antennulse (pi. XIII, fig. 88 a) is short, only about half as 

 long as the third. In the second pair of legs the dactylus with its ter- 

 minal claw or spine is longer than the propodus, and the claw is 

 slender and attenuated. The pleon is not wider than the segments of 

 the thorax, and the uropods have the outer ramus two-jointed and sur- 

 passing the basal segment of the inner ramus, which is five-jointed, with 

 the fiist segment long and imperfectly divided. 



Length 2.5"'™. Color white in alcohol. 



The specimens of this species were dredged in 48 fathoms, soft mud, 

 in Massachusetts Bay!, off Salem, by the United States Fish Commis- 

 sion, in the summer of 1877. 



Leptochelia rapa^ Harger. 



Leptoclielia rapax Harger, Proc. U. S. Nat. Mus., 1879, vol. ii, p. 163, 1879. 



Plate XIII, Figs. 89, 90. 

 Females of this species closely resemble those of the two preceding 

 species, but are distinguished by the following characters : The eyes 

 are larger and more conspicuous than in L. limicola. The last segment 

 of the antennulae is scarcely longer than the preceding, instead of nearly 

 twice as long. In the second pair of legs the dactylus is somewhat 

 shorter, and the terminal spine less attenuated. The external ramus of 

 the uropods consists of a single very short and small segment, shorter 

 than the basal segment of the inner ramus, which is not elongated. The
