532 REV. O. P. CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 
Fifthly. The spur which extends backwards from the outer side of the base of the - 
digital joint is shorter, and has a stronger outward and downward direction; and the 
prominence towards the extremity on the outer side of the same joint is stronger and 
nearer to the extremity. 
Sixthly. The apophysis from the outer extremity of the radial joint is more strongly 
bifid or notched, and is a little enlarged at that point: the palpal organs also are not 
so large. From C. carnifex it may be distinguished by the greater length of the radial 
joint in proportion to that of the cubital, as well as by the greater length of the digital 
joint, and the smaller development of the prominence near the extremity on the outer 
side of the digital joint. 
An adult female of this species was found by myself at Southport, in Lancashire, in 
1859, and has hitherto been regarded as a variety of C. carnifex; but on comparison with 
the Swedish types of C. nutrix, Westr., kindly lent me by Dr. Thorell, it appears to me 
to be undoubtedly of that species. The female resembles the male in colours and 
markings, the former of which are remarkably plainer than those of C. carnifex. 
Dr. Leach records C. nutrix as a British spider; but it is impossible to say what spider 
is referred to in his record (Supplement to the 4th, 5th, and 6th editions of the * Ency- 
clopædia Britannica,’ article ** Annulosa "), as he gives neither description nor figure, and 
there are, as we find now, at least three species to which his notice may possibly refer. 
An adult female, with an immature male, has lately been received from Mr. J. W. H. 
Traill, the former found near Aberdeen, the latter in Kincardineshire. 
CHEIRACANTHIUM ERRONEUM, sp. nov. (Pl. XLVI. fig. 5.) 
Clubiona nutriz, Blackw. Spid. Gt. Brit. & Ir. pl. viii. fig. 85, p. 134, exclude description. 
In Mr. Blackwall's work (loc. sup. cit.), C. nutrix, Walck. et al., is included, on the 
authority of Dr. Leach, among the indigenous British spiders; but there being no 
British examples extant from, which a description and figures could be prepared, the’ 
former was abstracted from the description of C. nutrix in Koch, * Die Arachn. ; while the 
latter were drawn from an adult male example received from the continent of Europe, 
and supposed to be of the same species as that described by Dr. Koch. This example is 
decidedly distinct from C. nutrix, Westr., which Dr. Thorell believes to be the true 
C. nutrix, Walck.; and it is also distinct from the C. nutrix, Koch, which has lately, 
and with good reason, been deseribed by Canestrini and Pavesi (Aran. It. p. 114) as 
C. italicum, sp. n., and figured in Cat. Sist. degli Aran. Ital.; Archiv. p. la Zool. l’ Anat. e 
la Fisiol, ser. ii. vol. ii. (1870), tav. iv. fig. 3. Its distinctness also from C. carnifex is 
very evident; I have therefore here described it as a new species. 
It is rather smaller than C. nutriz, Westr.; the cephalothorax has a distinct dark 
longitudinal central band (narrow and emarginate towards its hinder extremity), running 
from the hind eentral eyes to behind the cephalie and thoracic junction. 
The abdomen is richer-coloured ; the normal macula on the fore part of the upperside is 
of a rich red-brown colour; and this is followed, towards the spinners, by several indistinct 
angular lines of the same colour; the apices of these are directed forwards, and developed 
into a strong blotch; the normal macula, as well as the angular bars or lines, are sur-
