the propodos ; propodos oblonj*, narrower at apex ; seta"! not more 

 than lialt as long as the joint. Second pair of gnathopuda ending 

 in a spatuhvto joint, which is rounded at the apex, and has an 

 obsolete claw at the middle of the apical margin. First and 

 second pairs of gnathopoda setose below, the setce rather long ; 

 three posterior pairs gradually increasing in length ; the propodos 

 of the last pair slender, with the seta; hardly half the diameter of 

 the joint in length. 

 " Length of body five lines.

Anonyx variegatus, Stimjyson, Proc. Acad. Nat. Sci, U.S. 1855. 



Eyes reniform, black. Superior antcnnaj having the flagellum scarcely 

 as long as the peduncle ; second appendage foui'-jointed. Inferior 

 antennae not longer than the superior. First pair of gnathopoda 

 having the carpus longer than the propodos. Second pair of gna- 

 thopoda having the cai-pus longer than the propodos ; palm deeply 

 cleft ; inferior angle obtusely produced ; tufted inferiorly with short 

 hail's, and superiorly, at the extremity of the propodos, with long 

 ones, slightly curved and ciliated upon the concave margin, on the 

 convex furnished with a short process near the apex. Posterior 

 edge of the bases of the three posterior paii-s of pleopoda smooth ; 

 posterior pair of pleopoda with the rami not longer than the base. 



Length about ^oths of an inch.

The figure is taken from a specimen sent to me by the author. With 

 the exception of the deeply-cleft palm of the second pair of gnatho- 

 poda, I can perceive but little difference in it from L. Costce. 



6. Lysianassa appendiculata. (Plate X. fig. 8.) 



Lysianassa appendiculata, Kriii/er, Griin. Anifip. pi. 1. f. 2. 

 Edw. Hist, dcs C'nist. t. iii. p. 21. 



Eyes long, narrow above, broad below, curved (like an inverted 

 comma). Inferior pair of antenna; longer than the superior, ha\-ing 

 each joint of the flagellum broader than long, and furnished with 

 a small (shoe-shaped ?) calceola*. Posterior margin of the bases 

 of the three posterior paii-s of pereiopoda scirated. 



» Thifl term has been suggested and used by Stimpson for the small mombra- 

 nou8 appendages, which often resemble an inverted shoe, upon the llagcliuni of 

 the inferior pair of antennte. Mr. Stimpson informs me that they ciiariu-ten/.o 

 the males only- They certainly are not common (o all uiMlt-s, but appear to be 

 more numerous in Transatlantic ajjccies than in European.
