The genus Garipynus belongs according to this to none of them. The 

 <wo, now known species of this genus bave the femora of the two aii- 

 terior pairs of legs provided with a basai trochantin, which will bring 

 the genus into the familj' Cheliferidae, but ali the tarsi are 2jointeQ 

 and there are 4 eyes, which two facts bring the genus into the family 

 Garypidae. The general appearance of the one species of Garypinus, 

 Unown to me, is decidedly that of the Garypidae. In fact, as also ob- 

 served by Daday, this genus combines the two families and is an inter- 

 mediate form between them. Yet, there is no reason for constitutinu' a 

 new family for this genus, as Daday did; in spite of the trochantins the 

 animals bave certainly their nearest relations among the Garypidae. 

 But then the family character must also be somewhat altered and may 

 he put up thus: 



2. Gai*ypidae. 



The femora of the two anterior pairs of legs divided into a longer 

 pars basalis and a shorter pars tibialis, or with a trochantin. 



AH tarsi 2-jointed. 



4 eyes. 



According to commun'cafions from Prof. Silvestri the localities are 

 Monte Buenos Aires near L-igo Argentino at the souices of Rio S. Cruz 

 and some other places near the same ri ver, in Southern Patagonia. 

 I bave to thank Prof. Silvestri for bis good-will in giving me an oppor- 

 tunity to study these interesting animals.

Body and palps rusty brown, the intersLitial parties and the under 

 side of abdomen lighter.
