chelipedes are provided with four teeth, though the left 
chela is a little larger, and in a third example the right 
leg ot which is again the larger one, the right carpopo- 
dite presents a very small fifth teeth between the third 
and the fourth, the left, however, four teeth; in the re- 
maining smaller specimens the carpopodites are armed 
respectively with four and three teeth. 
Heller says: margine posteriore (carpi) non spinuloso. 
This is not quite exact. The posterior margin terminates 
at the distal end into a bispinose tooth, that is preceded 
by one or two smaller ones; the latter, however, are placed 
on the upper surface of the wrist, sothat they 
are not visible on the posterior margin itself. 
Heller therefore did perhaps not observe them or perhaps 
they are quite absent in the Vienna specimen, as Koelbel 
makes no mention of them in his letter. The arm bears a 
sharp tooth at the extremity of the anterior margin, and 
the exterior border that articulates with the carpopodite, 
presents two minute sharp teeth on the upper side and a 
similar spinule at the under surface. As regards the sculp- 
ture of the upper surface of the anterior legs, the Flores 
species fully agrees with the type specimen of Heller. I 
may observe concerning the following legs that in the 
Flores specimens the posterior margin of the meropodites 
of the fourth or penultimate pair presents only one single 
small tooth near the distal end, in the Vienna type spe- 
cimen, however, two small teeth, like as the posterior 
margin of the second and third pair, a slight difference 
considered by Koelbel as individual. As well in our speci- 
mens of Endeh, as in the type example of Heller, the 
carpopodites of the second legs i. e. of the first pair of 
ambulatory legs, are armed at the distal end of their anterior 
border with a sharp spinule, that has not been des- 
cribed by the author of the »Crustaceen der Novara-Reise”’. 
The anterior margin of the meropodites of the three pairs 
of ambulatory legs is armed on its whole length with sharp 
spinules. As regards the shape of the cephalothorax, and
