ON EUROPEAN SPIDERS. 199 
dentes remoti. Oculi 4 anteriores inter se proximi: medii (antici) eorum re- 
liquis omnibus multo majores. Tarsi unguibus tantum binis et fasciculo ungui- 
culari instructi. (Palpus feminæ ungui caret). . . . . . . . IL Attoide. 
Fam. I. ERESOIDA. 
Syn.: 1850. Eresides C. Kocm, Uebers. d. Arachn.-Syst., 5, p. 70. 
The two sub-families, into which we divide this family, certainly 
agree in the structure of the cephalothorax, the position of the eyes, and 
in their whole general appearance very closely with each other, but present 
the remarkable difference, that whereas the Æresinæ are provided with infra- 
mammillary organ and calamistrum, the Palpimanine are without these organs. 
The two genera Æresus and Palpimanus ( Chersis) had already by WALCKENAER!) 
and Durour ?) been placed in the closest connexion with each other and 
with Attus; SUNDEVALL ?) and C. Koch *) received them into the family At- 
tides, and when the latter afterwards detached them from that family, he 
united them with the new-formed family Æresides, which received a place 
immediately after the Attides >). — CANESTRINI and Pavesi 9) who unite 
Eresus with the Attoidæ, have formed a separate family, Cherside, for Pal- 
pimanus, a view which I cannot approve. How Simon 7) could refer Æresus 
to the Epeiroide and Palpimanus to the Myrmecioide is to me inexplicable. — 
We characterize the two sub-families and thereto belonging European genera 
as follows: 
I. Organum infra-mamillare et calamistrum adsunt. . . . . . I. ERESINX. 
1. Oeuli seriei terti: longe pone reliquos siti; laterales seriei 1"* ab inter- 
mediis ejusdem seriei longissime remoti. Tarsi omnes unguibus trinis in- 
structi. (Palpus feminz ungui armatus) Mamille breves. . 1. Eresus. 
IL Organum infra-mamillare et calamistrum desunt. . . . . IL PALPIMANINX. 
1. Oeuli seriei 3* paullo tantum pone oculos 2% seriei siti, cum iis seriem 
reeurvam formantes. Tarsi pedum 6 posteriorum unguibus tantum binis 
armati. (Palpus feminz ungui caret). . . . . . . . 2. Palpimanus.
