uous, placed above at the base of the rostrum. Superior antennae shorter 

 than the inferior, peduncle of both pairs rather elongated. Anterior lip evenly 

 rounded at the tip; posterior lip with the outer lobes rather broad, and pro- 

 duced outside to an obtuse projection. Mandibles with the molar expansion 

 imperfectly developed, rounded at the tip, and without the usual fluted tri- 

 turating surface, palp robust and having the last joint oblong oval in form. 

 First pair of maxillae with the masticatory lobe comparatively narrow, basal 

 lobe with a few plumose setee, palp well developed, but scarcely dilated 

 distally. Second pair of maxillse with both lobes oval in form and nearly 

 equal-sized. Maxillipeds with the basal lobes not very large, masticatory 

 lobes oval, reaching about to the middle of the 2nd joint of the palp, and armed 

 on tlie inner edge with a row of strong spines, on the tip and outer edge 

 with curved plumose setae, palp robust with large claw-like terminal joint. 

 Gnathopoda subequal in structure, the posterior pair being only a little lar- 

 ger, carpus in both pairs produced at the end inferiorly to a curved setous 

 lobe, propodos large and oval in form, with the palm very oblique. Pereio- 

 poda, with tlie exception of the last pair, short and stout, densely setous, 

 and having the dactylus lanceolate compressed. Last pair of uropoda not 

 projecting beyond the others. Telson rounded quadrangular. 



Ttemurlis — In the restriction here adopted, this genus is chiefly cha- 

 racterised by the distinctly deflexed rostrum, and by the gnathopoda being quite 

 eqvial in structure. In both these points it is easily distinguished from the 

 following nearly-allied genus Parocdiceros. It comprises as yet only 2 spe- 

 cies, to be described in the sequel.

Body rather inflated, especially in the ovigerous female, the mesosome 

 being even somewhat broader than it is deep, segments of metasome slightly 

 carinated above. Cephalon abovit the length of the first 2 segments of mesosome 

 combined, rostrum abruptly deflexed so as to make the upper contour of the head 

 geniculate in front, its tip sharply pointed and reaching nearly to the end of 

 the basal joint of the superior antennae, lateral corners of cephalon rectangular. 

 Coxal plates scarcely deeper than the body; 1st pair rather small and evenly 

 rounded at the tip ; 4th pair rounded quadrangular, scarcely at all emarginated 

 posteriorly, and having the infero-posteal corners rounded off; 5tli pair rather 

 broad, with the posterior lobe the larger. Eyes placed within a rounded promi-
