CRUSTACEA OF THE MERGUI ARCHIPELAGO. 13 
direction of the spines of the antero-lateral and posterior margins, 
by the upper surface of the carapace being scarcely tuberculate, 
by the minutely granulate hands, and, finally, by the much more 
elongated legs. 
I have much pleasure in dedicating this new Doclea to Pro- 
fessor Anderson. 
3. DoctEA, sp. 
The Collection contains two other much smaller male speci- 
mens of a Doclea, also collected in the Mergui Archipelago. 
These Doclee are somewhat allied to the former species, but 
may be distinguished by the following characters :—first, the 
three anterior teeth of the antero-lateral margins are rather 
obtuse, being, however, also equal in length, but the last spine 
is comparatively much longer; secondly, the two minute, scarcely 
prominent median tubercles with which the upper surface 
of the cephalothorax of D. Andersoni is provided are repre- 
sented in these specimens by two rather strong spines; and, 
thirdly, the second pair of legs are comparatively shorter 
than in that species. 
As regards the shape of the carapace and the relative length 
and shape of the joints of the ambulatory legs, these specimens 
closely resemble D. Andersont. The cephalothorax of the larger 
individual is 16 millim. long and 17 millim. broad; the three 
anterior teeth of the antero-lateral margins are scarcely 1 millim. 
long, but the acute posterior tooth, which is directed slightly 
forward and upward, measures 33 millim. The legs of the second 
pair, measuring 54 millim., are only a little longer than three 
times the length of the cephalothorax. 
The carapace of the younger specimen is only 83 millim. long 
and 9 millim. broad. In this individual the two median spines, 
on the middle of the upper surface of the cephalothorax, are 
comparatively still longer, and the last tooth of the antero- 
lateral margins is 8 millim. long, so that it measures about a 
third of the breadth of the carapace. The second pair of legs 
are 25 millim. long, and thus precisely three times as long as 
the length of the cepbalothorax. The median spine of the 
posterior margin is comparatively as long in these specimens as 
in D. Andersont. 
Finally I may add that in these specimens, as in the preceding 
species, the upper surface of the cephalothorax, especially of the
