Remarks.—This species keys out with T. wakensis Edmondson 
(1925) and T. picta Stimpson (1858). (See Stephenson and Hudson, 
1957, p. 316.) It is closest to T. wakensis, sharing with it possession 
of a distinctly granular basal antennal joint and a male pleopod with 
stout anteriorly directed bristles on the outer side near the tip. It 
differs from T. wakensis in: 
a. More rounded median and submedian frontal lobes; see 
Edmondson (1925, fig. 7a; 1954, fig. 36a) and Sakai (1939, fig. 13a). 
b. Longer and less arched inner orbital lobes lying farther behind 
the front. Only in the two smallest specimens are the lobes relatively 
arched. 
c. Reduction of spines to tubercles upon the wrist and arm; see 
Edmondson (1925, fig. 7c) and Sakai (1939, fig. 13c). 
d. The absence of a distinct cardiac ridge on the carapace. 
e. The different shape of the male pleopod. In the present 
material, there is no subterminal broadening of the appendage as 
shown in Edmondson (1954, fig. 36c), and the numbers and shapes 
of the terminal bristles differ conspicuously from those figured either 
by Edmondson (1954, fig. 36d) or Sakai (1939, fig. 13b). 
A male (25 mm., Sta. 5254, May 18, 1908, Alb.) has the ultimate 
segment of its male abdomen much shorter and more rounded than 
the remainder (see fig. 31e).
