flattened, roughly rounded lobe with denticulate or small tuberculate 
margin. 
The posterior border of the propodus of the fifth or swimming leg 
is armed with spinules. As viewed from above there are four short, 
stout, acute spinules — one could well call them spines — on the right 
propodus this side of the close-set fringe of long hair that marks the 
anterior (upper) margin of the joint and a single one the other side, 
behind the fringe of hair, inserted proximal to the proximalmost of 
the four spinules dorsal to the fringe of hair ; on the left propodus 
there are eight spinules above or dorsal to the fringe of hair and three 
behind, these three are inserted distal to the second of the spinules of 
the upper side ; the first two spinules on the upper side of the fringe of 
hair on the left propodus are colorless, small, and relatively incon- 
spicuous for that reason ; the other spinules for the most part show 
more or less reddish color. In T. alcocki the hinder margin of the 
propodus of the fifth pair of legs is armed with 5 sharp spinules ; in 
T. gar diner i with 10. 
Color. — Of the alcoholically preserved type: Granulations showing 
through the pubescence of the carapace, and the crenulations of the 
keels or ridges ornamenting it are reddish. 
The movable finger of the chelae is white-tipped, followed by a 
brownish transverse l)and, then a white hand of about the same width. 
Neither band is as wide as the white ])ortion of the tip, and both 
together occupy about as much space as the reddish brown basal por- 
tion of the finger. The middle third of the fixed finger is lirownish, 
distal and proximal thirds white. 
The lateral spines of the carapace are red tipped and there is a fleck 
of the same color near the base on the outer margin of each of the 
lateral teeth except the fourth ; behind the corresponding fleck on the 
fifth lateral spine there is a second spot of color farther down or pos- 
terior to the first fleck, a little more removed from that fleck than it 
is from the colored tip of the spine ; the tubercles and granules of the 
chelipeds are also of a reddish color ; the spines arming the hands are 
color-marked like the lateral spines. The ambulatory legs are dull 
blackish brown barred : there are two transverse bars of this dark 
color on the dactyl, a very wide one around the middle of the propodus, 
a similar one around the carpus, and two narrow ones about the merus. 
Remarks . — From the species of 7 halanuta that fall within the pur- 
view of Alcock’s group II. A ( Journ. Asiatic Soc. Bengal, vol. 68, p. 
73, 1899) ours is at once distinguished from T . invesfigaions and rni- 
parimanus , and I believe also from T. tenmpes, by the fact that in 
these species the hinder margin of the propodus of the last pair, or
