CLUBIONA.

is smaller than that of the female, and of a yellowish-ochreous colour (whitish when viewed 
obliquely), but has rather a reddish tinge in the posterior region of the upper part; the 
longitudinal band in the middle of the anterior half has a brownish-rusty hue; and the 
branchial opercula are of a fine yellow colour. 
According to Dr. Leach, this spider has been taken once in England, near Cheltenham. 
See the Supplement to the fourth, fifth, and sixth editions of the c Encyclopaedia Britannica,’ 
article “Annulosa.” 
As the identity of the Clubiona nutrix of M. Hahn with the species whose name it bears 
is not clearly ascertained, it will suffice to remark that M. Walckenaer has assigned to it a 
place among the synonyma of Clubiona erratica, and that M. Koch entertains the opinion that 
Hahn’s description is referable to the former species, and his figure to the latter; his words 
are, “der Beschreibung nach hatte Hahn unbezweifelt Club. Nutrix, Walck. vor sich, 
dagegen deutet freilich dessen Abbildung auf Club, erratica.” (‘ Die Arachn.,’ Band vi, p. 15.)

Length of the female, ^ths of an inch; length of the cephalo-thorax, ^ths, breadth, Ath; 
breadth of the abdomen, 5 |ths; length of an anterior leg, fths; length of a leg of the third 
pair, T 3 5 ths. 
The legs are long, slender, provided with hairs, and of a light, yellowish-brown colour; 
the first pair is much the longest, the fourth pair surpasses the second, and the third pair 
is the shortest; each tarsus is terminated by two curved, pectinated claws, and below them 
there is a small scopula. The palpi resemble the legs in colour, with the exception of the 
extremity of the digital joint, which has a brown hue, and appears to be somewhat dilated. 
The cephalo-thorax is slightly compressed before, convex, glossy, thinly clothed with hairs, 
depressed and broadly truncated in front, and of a reddish-brown hue. The falces are 
powerful, conical, vertical, fringed with hairs on the inner surface, and of a red-brown colour, 
except at the extremity, which has a blackish tint. The maxillae are straight, enlarged and 
rounded at the extremity, and rather paler than the falces. The lip is curved on the sides, 
truncated at the apex, and of a reddish-brown hue. The sternum is heart-shaped, having 
small eminences on the sides, opposite to the legs; it has a yellowish-brown tint, with broad, 
brownish-black, lateral margins. The eyes are disposed in two transverse rows on the 
anterior part of the cephalo-thorax, those constituting the anterior row, which are situated 
immediately above the frontal margin, being rather the largest; the eyes of each lateral pair
