Bd. II, 1892, p. 379, Pl. XXII, fig. 25), but difffers by 
the different form and shape of the rostrum. 
Like the above-mentioned species, which inhabits the river 
near Pare-Pare on Celebes, also Car. timorensis belongs to 
the species of a small size, as it measures only 17 or 
18 millim. and brings likewise forth a small number 
of large eggs, which are 1,2 millim. long and about 
half as broad. 
The rostrum which is short, presents about the same 
form as in some varieties of Car. Weberi de Man (l. c. Taf. 
XXII, fig. 23f), is horizontal or more or less directed 
downward and mostly reaches a little beyond the first joint 
of the antennal peduncle, sometimes to the middle of 
the second joint, sometimes, however, not farther than 
to the distal end of the first joint. The upper margin bears 
3—5 small teeth, placed usually on the anterior half of 
the rostrum, more or less distant from the apex, at equal 
or unequal distances from one another, and none of which 
are placed on the cephalothorax. In a few specimens the 
upper margin presented only one or two teeth, they wan- 
ted completely in four examples, the upper margin being 
entire — in one specimen, on the contrary, I observed 
six teeth. The lower margin is armed anteriorly also with 
3—5 contiguous, very small teeth. The antennal spine is 
distinct. The telson which is slightly tapering towards the 
distal end and which is a little shorter than the rami of 
the uropoda, bears four pairs of spinules on its upper sur- 
face; the distal end is armed with five pairs of spinules, 
of which those of the first, at the external angles, are 
very short and the shortest of all, being as long as the 
spinules of the upper surface, those of the second pair are 
four times longer and the longest of all, and the three 
remaining pairs are a little shorter than the second and 
nearly all of the same length. 
The eye-peduncles are as long as the basal spine of the 
upper antennae, which is a little shorter than the first 
joint of the pedunele. The second joint is slightly shorter
