In 1885 a paper (14 pages) was published (Naturalista Si- 

 ciliano, Anno IV): »Intorno ad un nuovo Aracnide Arthrogastro 

 {Kocncnia mirabilis) che crediamo rappresentante d'un nuovo Or- 

 dine {Microtclip/uniida) per il Prof. B. Grassi (in collaborazione 

 coir Assistente S. Calandruccio).» The next year Grassi pub- 

 lished his well-known essay on the same subject (Bull, della Soc. 

 Entomol. Italiana, Anno XVIII, Firenze, 1886, p. 153 — 172, 

 Tav. IX — X). In 1888 Thorkll (Ann. Mus. Civ. di Stor. Nat. 

 di Genova, Ser. 2, Vol. VI, y>. 358) proposed the excellent 

 name Palpigradi for the order, suppressing — and I think with 

 good reason — that given by Grassi (and Calandruccio) as 

 being a misleading one. In one of the first months of 1898 

 appeared the fourth part of Entomol. Tidskrift, Arg. 18, 1897; 

 it contained an essay by H. J. Hansen & William Sorensf.n: 

 Tlie Order Palpigradi Thor. [Kociieuia viirabilis Grassi) and 

 its relationship to the other Arachnida (p. 223 — 40, Tall. IV). 

 We possessed only female specimens of the Italian species, which 

 was redescribed and illustrated by new figures. In the following 

 pages I have to made about three small corrections and some 

 additions to our text (and figures), but as to all other particulars 

 the reader is referred to our older paper. Only some few re-
