306 CRUSTACEA, 
bearing females, with the exception of a single fullgrown 
male, that bears still the legs of the second pair. This 
male specimen is 52 millim. long, the rostrum included, 
and thus a little longer than the largest male in the col- 
lection of Max Weber, that had a length of 44 millim. 
The rostrum reaches to the distal end of the second joint 
of the antennal peduncle; six of the ten teeth of the upper 
margin stand on the cephalothorax, and the lower margin 
shows two teeth. Like as in the mentioned male, that 
was collected by Prof. Weber on the island of Saleyer, 
the larger leg of the second pair is found on the right 
hand and fully agrees with that of the other specimen. 
The meropodite is 15 millim. long and the carpopodite 
17 millim., whereas the latter is 5 millim. broad at the 
distal end; the chela has a length of 28 millim., the fin- 
gers are 12 millim. long. The palm which is 16 millim. 
long, is 6!/, millim. broad and 4'/, millim. thick, conse- 
quently compressed in the proportion of 3:2. The fin- 
gers are a little more slender than those of the male of 
Saleyer, but are for the rest quite similar. The meropodite 
of the shorter leg is 10 millim. long, the carpopodite 
12 millim., the palm 10 millim. and the fingers 9 millim.;: 
and this leg also agrees with that of the other specimen. 
The spinulation of these legs is also the same in both in- 
dividuals. 
The ten female specimens of Great-Bastaard are a little 
smaller than the described male, their length varying be- 
tween 38 and 42 millim.; they are all nearly of the same 
size. Only one single female, 38 millim. long, is still 
provided with both legs of the second pair: the fingers 
are scarcely or not shorter than the palm; this is also 
the case with three other examples, which bear still one 
leg of that pair. One of these specimens shows a singular 
monstruosity. Only the four first or proximal teeth, that 
stand on the cephalothorax, are developed, and the ro- 
strum is represented by a strongly arcuate hook, which 
is sharply acuminate, with the point directed downward,
