in the peculiar character of the 6th pleon segment and telson, and in 

 the appendages except the 1st peraeopod (gnathopod). 



Side-plate of 1st free segment quadrate but not produced. Flagellum 

 of 1st antenna 5-jointed, of 2nd 3-4-jointed. 



The 1st peraeopod is very stout and robust, 2nd joint oval, nearly 

 as broad as long, 4th and 5th short and stout, together equal to the 

 2nd, 6th a little longer than 2nd, inner margin of thumb with a 

 tubercle in the middle and a crenulate cutting-plate nearer the apex, 

 finger indistinctly denticulate with a larger tubercle in the middle and 

 another nearer the hinge ; no exopod. 



Male appendage on 7th segment a small, knob-like process. 



In neither of the specimens could any pleopods be found, except the 

 1st pair in one of them. If this were indeed a normal characteristic 

 the species would require a new genus for its reception ; but I am 

 unwilling to do this until more material has been collected. Live 

 specimens would be the best, but as the only 3 specimens I have so 

 far come across have been picked out of a multitude of various 

 Amphipods, Isopods, Polychaets, dtbris, etc., after a day's collecting, 

 only by a very fortunate chance will a live one be secured.

APSEUDES AGULHENSIS n. sp. 

 (Plate XV. Fig. 1.) 



Body very narrow and elongate. Carapace longer than broad, lateral 

 margins evenly sinuous, rostrum broader than long, triangular with 

 slightly sinuous margins and acute apex. Ocular lobes not spiniform 

 but ending in a minute acute point. 



Peraeou segments 2 and 3 wider than long, 4-7 subquadrate, only 

 5 and 6 with a small acute point on the autero-lateral angles. Side- 

 plate of segment 2 acutely produced. 



Pleon segments 1-5 laterally obtuse, 6 not quite as long as 1-5 

 together, twice as long as broad, scarcely tapering, apex obtuse. 



First antenna, 1st joint 5 times as long as wide, margins entire, 

 2nd equal to width of 1st, 3rd shorter, flagellum 8- jointed, equal to 

 1st peduncular joint, accessory flagellum half length of main one, 

 3-jointed. 



Second antennae a little longer than peduncle of 1st, 2nd joint 

 linear, scale linear, half length of 2nd joint, 4th and 5th subequal, 

 flagellum equal to 3rd-5th peduncular joints, 6-jointed,
