Adult female, length 9 lines (19 mm.).

In general appearance, colours, and markings this spider bears great resemblance to N. cæmentaria. The eyes, however, appeared to be smaller, and the hind-centrals also smaller in proportion to the rest. The pale margins of the cephalothorax are in the present species generally confined to some rather indistinct pale patches.

The central orange band from the eyes to the thoracic fovea is, especially in immature examples, often only a simple tapering line; in others it is larger, and often composed of three converging narrow orange bands, which form, in some examples, a broad central tapering band, marked with two longitudinal dark lines. The thoracic fovea is curved, but not sharply.

The abdomen is broadish oval, of a dull clay colour, marked with dark brown lines, and markings on the sides and upper side. In some examples these form a longitudinal central series of curved or slightly angular lines; in others but little trace of regular chevrons can be seen.

In the present spider there is also a longitudinal pale yellowish patch on the inner upper margin of the falces near their base; they are furnished with hairs in longitudinal bands, and spines, like others of the genus.

The legs are moderately long, strong, and furnished with hairs and bristles, and, sparingly, with spines. The genual joints of the third pair have some spines on the outer side, varying from one to three in different examples. The tarsi and metatarsi of the first and second pairs, as well as the radial and digital
