eyes being much greater than that between each of these and that of the upper pair on its 
"side; the space between these last is very nearly equal to that between the fore lateral 
eye and that of the lower pair on its side. | 
Legs moderately long and strong; relative length 4, 1, 2, 3; colour red-brown, femora 
darkest. They are furnished with hairs, among which are some longish, very slender, 
erect ones, on the uppersides of the genual, tibial, and metatarsal joints. 
Palpi not long, nor strong, paler-coloured than the legs, except the digital joints, which 
are dark brown. Cubitals curved, strongest at extremities, radials shorter, but much 
stronger; they are much and broadly produced on the uppersides in front, extending half- 
way over the length of the digital joints; the outer edge of the part produced is slightly 
hollowed ; the inner extremity of the production narrows into a long spiny point, curving 
sharply outwards and round the extremity of the produced part. Digital joints oval, not 
very large, and, as well as the radials, furnished with hairs. Palpal organs well developed, 
but not very complicated, consisting of corneous lobes and processes, with a small pointed 
black spine issuing from their extremities. 
Falces moderately long, strong, straight, inclined towards the sternum, and similar in 
colour to the cephalothorax. 
Maxille similar in colour to the falces, strong, greatly enlarged laterally at the inser- 
tion of the palpi, obliquely truncate at the extremity on the outer side, and inclined 
towards the /abiwm, which is very short and semicircular, and of the same colour as the 
sternum. 
Sternum large, broad, heart-shaped, convex, and granulous (or roughened), with im- 
pressed punctures, and furnished with short erect hairs; colour very dark rich black- 
brown. 
Abdomen short-oval, very convex above, and projecting considerably over the base of 
the cephalothorax; colour sooty-black, shining, thinly clothed with short hairs; spinners 
and spiracular plates dull yellowish brown. 
An adult male of this minute spider was captured among moss and dead leaves at 
Bloxworth, in May 1863*. It is allied to W. latifrons, W. hiemalis, and W. aggeris, 
but differs not only in size, but specially in the form of the cephalothorax, position of - 
the eyes, and structure of the palpi and palpal organs. 
WALCKENAÉRA CIRRIFRONS, n. sp. (Pl. 57. no. 43.) 
Male adult, length 5}; of an inch, or 2 of a line. 
Cephalothorax oval, rounded, and slightly narrower at the fore extremity than behind ; 
glossy and of a rich dark brown colour, except the upper part of the caput which is 
much paler (but query whether this is constant); under a lens it is thickly covered 
with minute punctures, except the upper part and the front of the caput. 
Caput massive and elevated, but not greatly; the elevation is rounded at the top —— 
slopes a little more behind than before, and its height shown by a deep longitudinal — 
indentation, which runs back immediately from behind each lateral pair of eyes, and
