 (With Plate 2, fig. 31—33.) 



Length 1300, breadtii 900 ii. 



Tliis animal was caught by Mr. J. Jaspers Jr. in Amsterdam. 

 I believe, however, that it is a creature of warmer regions, being 

 accidentally brought to our country. It remembers us of tropical 

 forms. 



I have only one female, wich probably is not an adult one, 

 for it has an ^^^M*-like genital shield, and a hair behind the anus, 

 but which certainly is generans, and even a viviparoiis one, for 

 a larva was in it (Fig. 31). 



The dorsal side (Fig. 31) shows one dorsal shield, the circum- 

 ference of which is crenulated, bearing a curved stiff bristle in 

 each incision. The surface is smooth , but has some symmetrically 

 arranged, chitinous, slightly elevated markings, one in front, bowed 

 slightly forward, two little ones on the level of the shoulders, 

 bowed slightly backward and bearing a short thick bristle , two on 

 the sides, bent inward and backward, and two long, somewhat 

 undulated, longitudinal ones, looking sideward. These latter show 

 a little chitinous apparatus, within or beneath the dorsal shield, 

 which I think to be a tube and probably an outlet of a gland. 

 The dorsal shield bears four pair of curious hairs ; their proximal 

 half is broad, their distal one line, and the hair itself is nodded 

 suddenly sideways. The other five pair of bristles are of the usual 

 type. The margin of the body is indulated too and the posterior 

 margin bears numerous .short bristles curved inward and downward. 



The epistoma is nearly straight, but bears in the middle a flat 

 lanceolate projection, which I could only see very indistinctly. 



The palpi are slender and as usual.
