ends in a short acute apex and is only half as long as wide. At either side of the tip 3 

 spines are implanted, the i^' is 0,4 mm. long, reaches by almost its whole length beyond the 

 apex and is feathered, the 2"'', 0,52 mm. long, the longest of all, is glabrous, the 3'''' at the 

 outer angles as long as the dorso-lateral spinules. Inner uropods narrow, distinctly shorter than 

 the telson, outer uropods a little shorter than the inner. 



Eyes large, the greatest diameter measuring one-si.\th the length of the carapace ; cornea 

 of a dark purplish colour, facets rather large. 



The antennular peduncle Reaches to just beyond the middle of the antennal scale, antero- 

 external angle of basal joint spiniform, subacute and a smaller spine occurs on the distal margin 

 of this joint; 2"'' and 3"^'^ joint together shorter than 1^', 3^<* a little longer, but less broad, 

 than 2"''; lateral process lamelliform, rounded, a little shorter than i"*' article; upper flagellum 

 mea.suring one-third the length of the carapace, reaching by half its length beyond the antennal 

 scale and rather broad, just as broad as the middle of the rostrum. 



Tooth at the infero-e.\ternal angle of 2"*^ antennal article obtuse with a minute acute 

 tip, peduncle a little shorter than the scale. Antennal scale (Fig. 65^) 1,75 mm. long, one-third 

 the length of the carapace, rostrum included, twice as long as broad, the greatest width just 

 behind the middle; it narrows moderately anteriorly, the slightly arched distal border is still 

 rather broad and makes an obtuse angle with the inner margin; terminal spine not or hardly 

 exceeding the apex of the lamella, outer margin straight, unarmed. 



External maxillipedes reaching by almost the whole length of their ultimate joint beyond 

 the antennal scale, ultimate joint one and a half as long as the penultimate. 



The i^' pair of peraeopods (Fig. 65^) project by three-fifths their propodus beyond the 

 antennal scale. Merus slender, with a very small, acute spine at the distal extremity of 

 the upper border and with the margins setiferous; the carpus appears in a lateral view one 

 and a half as long as thick and is unarmed; propodus of subchela half as long as the 

 carapace, rostrum included, slender, 4,6-times as long as wide in the middle, 

 "thumb" measuring '/j, the length of the propodus, slender, 3-times as long as broad at its 

 base and formed of a single acuminate spine. 



The second peraeopods extend to the far end of the merus of the i'*' ]>air and are clothed 

 with long .setae. Carpus 0,6 mm. long, 3-times as long as thick distally. Chela a little longer 

 than carpus, palm slightly broader than long, fingers 3-times as long as the palm, a little 

 gaping, immobile finger distinctly broader than the dactylus. Third legs very thin, as long as 

 the 1^' pair. Fourth (Fig. 65/) and 5"^ pair (Fig. 65_o-) stout, 4''' stouter than 5'''. The 4''' pair 

 reaches hardly beyond the antennal scale, the 5'"^ hardly beyond the 2"' joint of the antennal 

 peduncle. Carpus of 4"' pair 0,96 mm. long, 0,38 mm. broad, 2,5-times as long as broad. 

 Propodus 1,6 mm. long, about 1,7-times as long as the carpus, broadest at the [jroximal third, 

 the greatest breadth one-sixth the length. Dactylus slender, tapering, nearly straight, half as 

 long as the propodus. Excepting the dactylus this leg is fringed with long hairs especially along 

 the upper margin. The carpus of the 5"^ leg is 1,06 mm. long, a little longer than that of the 

 preceding pair, and 3,5-times as long as broad in the middle. Propodus 1,9 mm. long, longer than 

 that of the 4''' pair, 8-times as long as the greatest width at the proximal sixth and narrowing regularly
