CINIFLO.

•with several apophyses; one situated in front, towards the inner side, is slightly curved and 
somewhat pointed; another, on the outer side, is straight and rounded at the extremity; and 
between these two there is a short projection, having two processes, one obtuse and the 
other pointed; underneath, the extremity of the joint is bifid; the digital joint is somewhat 
oval, with a prominent lobe on the outer side, and a bold protuberance at the upper part, 
near its articulation with the radial joint; it is convex and hairy externally, concave within, 
comprising the palpal organs, which are highly developed, complicated in structure, with a 
strong, curved process and some delicate, white membrane at their extremity, and a large, pro¬ 
minent part, contiguous to which there is a small, curved process, situated near the middle; 
their colour is red-brown. 
Remarkable differences in structure, functions, and economy effectually serve to distin¬ 
guish the spiders belonging to the genus Ciniflo from those of the genera Clubiona and 
Amaurobius , with which they have been associated by arachnologists; all of them have an 
additional or fourth pair of spinners, and on the superior part of the metatarsus of each 
posterior leg there is a calamistrum, consisting of two parallel rows of moveable spines, which 
is employed in the fabrication of their extensive and curiously constructed webs ; they are 
also sedentary in their habits, most frequently occupying crevices in rocks, walls, or the bark 
of old trees, between which and their snares a communication is effected through the medium 
of one or more slight, silken tubes. Though the importance of these characters is admitted 
by M. Walckenaer, yet he still retains the species of Ciniflo among the Clubiona (‘ Hist. Nat. 
des Insect. Apt.,’ tom. iv, pp. 444, 445). 
The female of this common spider in the month of June deposits about seventy spherical 
eggs, of a pale-yellow colour, not agglutinated together, in a cocoon of white silk of a loose 
texture, measuring seven twenty-fourths of an inch in diameter ; it is nearly of a plano-convex 
figure, and is connected with the interior surface of an oval cell of white, curled silk, on the 
outside of which bits of soil and other extraneous materials are distributed. This cell is 
generally constructed in or near the spider’s retreat. 
On the 14th of September, 1842, an adult female of this species was captured, in which 
the left intermediate eye of the posterior row was entirely wanting. 
The dimensions of Clubiona ( Ciniflo ) atrox given by M. Hahn (‘Die Arachn.,’ Band i, 
p. 115) have, most probably, been taken from Ciniflo similis or from Ciniflo ferox. 
This species is of frequent occurrence in Scotland and Ireland.
