Lucas (Rev. et Mag. Zool. 1869, pp. 160-164) discusses the nature of the 
additional joint which occurs in the palpi of ActinojmSf and occasionally in 
the tarsi of Ilersilia. 
Bueykr (Comptes Rendus Soc. Ent. Beige, 1867, pp. liii-lvi) discusses 
the means by which Spiders unite distant places by means of threads, and 
communicates a letter from Terby on the same subject {l.c. p. Ixii). 
Giebel (Zcitschr. gos. Naturw. xxxiii. pp. 248-253) notices a few species 
of Spiders from the State of Illinois. The known species referred to are Attus 
auridcm (Bose) and Epeira apoclisa (Walck.). 
SoRBELLi has published (Atti Soc. Ital. Sci. Nat. xi. pp. 469-476) a list 
of Lombardian Spiders, with a few preliminary remarks. 
A list of the Spiders collected on the Qotska Sandon is given by Thobell 
(Q 5fvers. Kongl. Vet.-Akad. Forh. xxv. p. 379). 
MYGALIDiE. 
Thorell (European Spiders, part I.), as already stated, in- 
cludes three families under his suborder Territelarioi ; but of 
these only one, his Theraphosoid(Sy representing the Mygalidae 
of most authors, is represented in Europe. He gives the follow- 
ing table of the European genera (/. c. p. 164) : — 
I. Maxillm versus basin dilatatm j palpi dilatation! lateris affix! ; cephalo- 
thorax anteriora versus dilatatus 1. Atypus (Latr.), 
II. Maxillae angustae, subeylindratae ] palpi apice earum inserti. 
A. Area oculorum 2|-3-plo latior quam longior ; cephalothorax antice 
alte elevatus pedes breves, robust!, 3‘'“ paris reliquis breviores.
