The female of this species has hitherto remained undescribed. 
Female. First antenna, Ist joint widest and longest, 3rd not much 
larger than Ist flagellar joint, flagellum shorter than peduncle, 5- 
jointed, both peduncle and flagellum very sparsely spinose. 
Second antenna, ultimate peduncular joint not twice as long as 
penultimate, flagellum not as long as peduncle, 13-jointed, peduncle 
and flagellum very sparsely spinose. 
First gnathopod simple, although the inner apical angle of 6th joint 
is distinct, finger a little shorter than width of 6th, stout, unguis half 
length of finger. 
Second gnathopod, 2nd joint not strongly expanded on anterior 
margin, apical process of 6th rounded, but not at ail curved upwards. 
The following details apply to both sexes : 
First maxilla, inner plate with 2 plumose setae, outer plate with 9 
spines. Remaining mouth-parts as described below for T. quadri- 
spinosa. 
Second peraeopod, 7th joint oblong, with a sudden constriction near 
apex, Inner margin proximal to the constriction bisinuate and slightly 
concave, unguis 4 length of finger. 
Third and fourth peraeopods, hind margin of 2nd joint with shght 
setiferous indents. 
Fifth peraeopod, hind margin of 2nd joint slightly crenulate and 
bearing on distal portion long setae. 
First and second uropods, rami subequal, much shorter than 
peduncle in Ist, a little longer than peduncle in 2nd uropod. 
Third uropod, ramus and peduncle subequal. 
Telson rounded, with small apical incision, strongly spinose. 
In the male the finger of the 2nd gnathopod has a semicircular 
incision at base of inner margin for the reception of the tubercle on 
palm. 
In a specimen 15 mm. long the palm of 2nd gnathopod has only a 
very slight indication of the concavity characteristic of the adult ¢;
