joint of the ambulatory limbs and on the basal joint of 
the mandibles, but he has in those places found almost 
all that exist. He denies their occurrence on the palpi, 
remarking »ce qui distingue les Phalangides des Ara- 
néides«. Now I shall describe what I have found in the 
female of the same species, which ought rather to be 
called Phal. cornutum L. For the rest it is difficult to 
examine this animal owing to the nature of the inte- 
gument; of the same reason I have not tried to go into 
details in describing the organs of the body; but I have 
minutely described the organs in Memastoma lugubre 
O. F. Muller, belonging to a small family, Nemasto- 
moidce, standing between the Phalangioide and Trogu- 
loidæ (see W. Sorensen op. cit. p. 577—78), it being 
much easier to observe them with certainty in this 
form. Trogulus has also been examined by Gaubert, 
who has found organs on the mandibles and ambulatory 
limbs, yet the position of the fissures on the ambulatory 
limbs has not been further described. 
1) Phalangium cornutum fem. 
istepaum or legs: 
ist joint. At the basis c. 3 closely placed oblique 
fissures. At the apex of the apophysis of the posterior 
side a tolerably long transverse fissure. 
2d joint. On the anterior side close to the lower 
side a group of 6 shorter oblique fissures. Far down 
on the posterior side close to the apical margin about 
9 parallel, slightly oblique, closely lodged longitudinal 
fissures. 
3d joint. On the anterior side near the basis an 
irregular group of c. 10 short transverse fissures, most 
of which are strongly curved; on the posterior side a 
similar group. Besides some long transverse fissures 
spread over the joint quite to the apex.
