REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 405 
Abdomen oval, about equal in length to the cephalothorax, depressed, roundly truncate 
in front, where it projects considerably over the base of the cephalothorax; itis sparingly 
furnished with short bristly hairs; the upperside is of a deep rich red chocolate-brown 
colour approaching maroon ; it is bordered all round with a clear well-defined stripe of 
eream-white, and a broad longitudinal band of the same colour occupies the central line ; 
this band is strongly dentated from the middle to the spinners; the two principal of the 
hinder dentations, however, may more correctly be described as transverse slightly curved 
stripes of cream-white; these stripes generally terminate just short of the white border 
above mentioned, and are more or less perfectly connected with the central band; the 
five normal depressions are difficult to be seen readily; the cream-white central band 
has a double longitudinal row of dark red-brown spots, and is more or less suffused with 
yellow-brown. The sides (including the cream-white border of the upperside) are longi- 
tudinally wrinkled, and the wrinkles are spotted with dark spots or depressed points ; the 
underside is pale, freckled with light chocolate-brown and white. 
An adult male of this fine and distinctly marked spider was captured by myself in 
Bagley Wood, near Oxford, in May, 1866 *. and two examples of it have been met with 
near Bradford, Yorkshire, by R. H. Meade, Esq., who kindly submitted them to my 
inspection. I have since received specimens of it from Dr. Koch, of Nuremberg, under 
the name of Thomisus (Xysticus) audax, from which, however, it is remarkably distinct. 
I have given it the specific name of Westwoodii, to testify my appreciation of the great 
courtesy and assistance I have received from Professor Westwood in the prosecution of 
my arachnological studies at various times in the “ Hope” Department of the University 
Museum at Oxford +. 
THOMISUS SANCTUARIUS, n. sp. (Pl. 54. no. 8.) 
Male adult, length 1 to 14 lines. 
This species is allied both to T. trux (Bl.) and T. versutus (Bl.), but may at once be 
distinguished by its much smaller size and more sombre hue; more nearly allied to 7. 
claveatus (Walck.), it is also smaller than that species, but differs from it in colour, and 
from it and all other species known to me in the structure of the palpi, though nearly 
resembling those above mentioned in general structure and form. Its cephalothorax is 
of a brownish-black colour, obscurely mottled with yellowish, and narrowly margined 
with white. A broadish longitudinal yellow band occupies the median line, commencing 
behind the eyes, where it is somewhat bifid or notched, o and running backwards to the 
hind slope, which is of the same colour; this band is bisected longitudinally by a dark 
brown-black line, and has a darkish marking at its fore extremity corresponding with 
I have received an immature male of this species from Mr. W. Farren, of Cam- | 
the female from Mr. R. H. Meade, by whom they were captured at 
on the cephalothorax and abdomen, these are strikingly like 
being very considerably broader than the fore extremity,

bridge, found in Wicken Fen; also examples of 
Newport Purcell, near Bicester (Oxfordshire). In pattern, 
the male; and by the hinder extremity of the abdomen 
be easily distinguish ed from Thomisus cristatus. 
=> I have also am lately received this species from Sweden, from Dr. T. Thorell (of Upsala), who labelled them as 
the Thomisus (Xysticus) ulmi of Hahn, of which, however, the female only has been described by that author.
