296 REPORT 1868. 



Another marine species found among weeds at Hillswick, Shetland, 

 and also at Tobermory in the Isle of Mull. A much smaller species 

 than the last, and, if it were not for the greater number of joints in the 

 antenna, not unlike C. magniceps of Lilljeborg. 



Longipedia coronata, Claus, Die frei lebenden Copepoden, p. Ill, pi. xiv. 

 figs. 14-24. Abundant at Hillswick. 



Amymone falcata, n. sp. Superior antennae in female 8-jointed ; second joint 

 the longest, fourth shorter than any of preceding ; in male second and 

 fourth joints subequal, and twice as long as third. First segment in- 

 feriorly much produced, and extending backwards in an acute falcate 

 form. Hand long ovate, palm fringed with long cilia ; finger nearly as long 

 as palm, very slender. The coalesced sixth segment has the infero- 

 posteal corner produced backwards into a somewhat hamate spine-formed 

 process. Pereiopods long and slender, extending beyond the body. 



In most particulars this species comes near to A. sphcerica, Claus ; 

 but the first segment is widely different, being of similar form to that of 

 A. harpacticoides, Claus, but still more produced.

Genus TIGKIOPUS*, n. g. 



First feet having outer branches 2-jointed, both joints very long, last wide 

 at the extremity, with short recurved claws ; inner branch much shorter than 

 the outer, 3-jointed; basal joint very long, two following short. Gnathopod 

 (lower footjaw) of moderate size. Mandible palp 1-branched, 3-jointed.

 ord. tribus Clad. Ost. et Copep. p. 200, pi. xxii. figs. 2-11 (but not 

 Harpacticus chelifer of other authors). Lilljeborg's figures of this species 

 are good, and by comparing those of the gnathopod and first and last 

 feet with the drawings given by Claus of the same parts of the true 

 Harpacticus chelifer, the chief points of distinction will be at once mani- 

 fest ; the structure of the extremity of the outer branch of the first feet
