40 TULLGREN, SPIDERS COLLECTED IN SOUTH-CHILE BY P. DUSEN. 



Ihat to the apex of the joint a row of short spines. Con- 

 cerning the armature of the other side of these joints coin- 

 pare the descriptions of the different speeies. By the males 

 are no short spines together with long ones. Only by the 

 male of Gnolus cordiformis (Nic.) I have seen some few ones 

 on the inner side of metatarsus II. The legs are always 

 elothed with comparatively long and fine hairs. On the tarsi 

 near the claws the hairs are sometimes a little incised. That 

 is espeeially the case by Gnolus augulifrons Sim., which has 

 very broad and flattened, incised hairs arranged in rows on 

 the tarsi and metatarsi of the anterior legs. 



A comparison with the descriptions of the australian 

 genus Arcys and Archemorus of the group Arcj^ece shows 

 that the armature of these joints are nearly the same. As 

 for the genus Archemorus Mr Simon states them to have on 

 the inner side of the tarsus a row of short spines, forming 

 a continuation of the spines on the metatarsus. Such a case 

 I have mentioned above by Gnolus cordiformis (Nic). 



Concerning the claws of the tarsi we find in Hist. nat. 

 d. Araignées by Simon only that communication that their 

 structure is similar with that of Testudinaria. By the exa- 

 mined speeies I have observed some remarkable facts. By 

 Gnolus spiculator (Nic.) the superior claws of the first legs 

 are comparatively long and curved, along its whole length 

 there are a row of fine teeth. By the posterior pair of legs 

 the distal half of the claw is unarmed The tarsi have by 

 that as well as by all the other speeies some fine »ungnes 

 spurii». Nearh^ the same structure have all other speeies 

 exeept Gnolus cordiformis (Nic). By that speeies (see Pl. III, 

 fig. 6 b) the claws of the first pair of legs have a structure 

 very ditferent from that described above. The superior claws 

 are very short and stout. The base is very broad. The apex 

 is very little curved. In the concavity between the apex 

 and the broad basal part there are five very short teeth,^ 

 nearly vertically situated and of which the middle-ones are 

 the longest. The inferior claw has the apex very long and 

 fine, more forwards directed than by the other speeies. By 

 this structure of the claAvs this speeies shows a very near 

 affinity with the group Araje^e. As for that Mr Simon says 

 in Hist. nat. d. Araignées T. 1, fasc. 4, p. 900: >Les griffes 

 sent petites mais larges ä la base, tres fortement arquées.
