the limits of this family (compare, for example, Hadites tegenarioides and 
Tegenaria cinerea (cicurea)), that it does. not appear to me unjustifiable to 
refer to.it even genera, in which their 2" joint is so short, that it can only 
have spinning- -tubes quite at the extremity (Amaurobiine, Fe Agre- 
ca), or in which. it has been reduced to a mere flat lamina bearing the 
spinning-tubes, as appears to me to be the case in the genus Cybœus. 
That the inferior tarsal claw should sometimes be absent within a family, 
in which it is generally met with, is exemplified not only in the Dysderoide 
3 and Scytodoidæ (Loxosteles) but. „also in the Zresoide (Palpimanus), and I 
therefore consider that I ought. to aggregate Agræca to the Agalenoide and 
not to the Drassoide, although it has but two claws, for in its general ap- 
pearance it seems to. .me to approximate much more nearly to the former 
than to Be latter. 
in cannot a. be denied that the family Agalenoide, as I have 
- understood its compass, comprises tolerably heterogeneous en and I 
therefore break up the European forms belonging to it into 3 sub-families, 
Amaurobiineg Agalenine and Argyronetinæ. C. Kock also divided his "Age- 
lenides” (nearly answering to,the two last-mentioned sub-families) into 3 such 
groups: ”Eigentliche Trichter-spinnen”, "Wanderspinnen" and ” Wasserspin- 
»n 
nen". 'The middlemost of these is an unnatural section, containing species, 
* which ought to be distributed among the Agalenoidæ (: Philoica C. Kocm) 
; „and the Drassoide (: Anyphena). — We distinguish the sub-families and 
genera of the European fauna that belong to family Agalenoide according 
to the following scheme:
