tion; but those of the front row are equidistant from each other (the two central eyes 
of this row being nearly as far apart as the centrals of the hinder row), and dark- 
coloured; the two rows are near together; the clypeus is less in height than that of 
N. oblonga, not exceeding the length of the space occupied by the fore central eyes; 
the legs are stouter, and destitute of spines, and the terminal tarsal claws are rather 
conspicuous; the abdomen is furnished, but not very thickly, with rather strong, pro- 
minent dark hairs, giving it a bristly appearance; the sexual organs are externally of a 
red-brown colour, the aperture small and of a transverse oval form. A single specimen 
only of this species has yet come before me; it was captured in a similar situation and 
at the same time of the year as N. oblonga, from which, however, it may easily be dis- 
tinguished by the characters above given. 
NERIENE HISPIDA, n. Sp. 
Female adult, length + of an inch. . 
This species, in general colour, resembles very closely Neriene livida ; it is, however, 
smaller and stouter in appearance, but may at once be distinguished by the rugulose 
appearance of the front of the falces, which are powerful, straight, and vertical. This 
rugulosity occupies nearly the whole front surface, excepting a patch at their base and 
another at their extremity, where there is no flattish excavation as in JN. livida. The 
abdomen also is blacker and rougher, with short, strong, prominent hairs, and has not 
the spots and markings (which are characteristic of that species) so visible in spirit of 
wine ; it also projects greatly over the base of the cephalothorax ; the two central eyes of 
the hind row are nearer together than each is to the lateral on its side; and the four 
central eyes form very nearly a square, its fore side a little the shortest, those of the fore 
central pair being wider apart than is usual in this genus. These last are rather the 
smallest and darkest of the eight. The height of the clypeus is equal to the length of 
the space occupied by the four central eyes. 
The genual joints of the legs are slightly prominent behind, and rather on their inner 
sides, in a somewhat angular form; and from each prominence proceeds a spine-like 
bristle; besides this, the legs have numerous hairs upon them, differing, however, in 
length, strength, and direction, but none approaching so nearly to a spine as that above 
mentioned. In this form of the genual joints it also resembles N. livida. Its cephalo- 
thorax has a few short bristles on the eaput, and is glossy, and of a dark yellowish-brown 
colour, deepest in front, where it resembles that of the falees, maxillze, and labium; and 
the sternum is still darker. The legs are strong, moderately long, and their relative 
length is 4, 1, 2, 3; in colour they are similar to the cephalothorax, the femora being 
rather paler. : 
Adult females of this species were captured by myself under stones at Portland, in 
Oetober 1860, and have been since then named and described in MS. ; but the publication 
has been delayed hitherto in hopes of first getting the male. 
Dr. L. Koch thinks it is the Erigone robusta of Westring. The description, however, 
of that species in M. Westring's work omits any mention of the rugulosity of the falces,
