on »Les unes sont grandes, les autres beaucoup plus 
petites.« Not considering the fissures which are collected 
in groups at the distal ends of the legs, being without 
exception overlooked by Gaubert, I have found but 
very short and, moreover, not very numerous fissures 
spread on the dorsal side of some of the joints, which 
do not agree with Gaubert’s statement. Such a diffe- 
rence between the species of the same genus strikes 
me as being very unlikely, and thence it becomes de- 
plorable that we do not know which species he has 
examined; most of the species are, moreover, so closely 
connected, that it is difficult to distinguish and describe 
them well, a fact sufficiently proved in the literature. 
— We have no right to assert that the long fissures, 
mentioned by Gaubert, do not exist in any species, but 
as an object of curiosity I shall still point out that he, 
in the above quoted lines, refers to Pl. IV, fig. 4, which 
is a figure of a leg of Th. caudatus, but on this figure 
the above mentioned fissures are marked not »sur les 
cinq premiers articles des pattes« but only on the 5d 
and 5th joint, and the relative length of the joints is 
exceedingly wrong. 
The following representation of the lyriform organs 
is founded on the study of an adult female of Th. 
indicus Stol. Of the same reason as by Phrynide |

transverse fissures. 
2d joint. On the upper side close to the posterior 
side at the apical margin behind the apophysis numerous 
longitudinal fissures of very unequal length, the under- 
most ones collected in a large irregular group (Tab. 
III, fig. 1), in which the proximal fissures are short, the
