A single example of this very interesting and distinct species was received in 1879, from Capt. Hutton, by whom it was found at Dunedin, N e w Zealand. Although the male cannot be mistaken for that of N. gilliesii, if the above differences be carefully noted, it is probable that considerable difficulty may be experienced in distinguishing the females, excepting by the size, if, indeed, this character should prove a constant one. It is more than probable, however, that the trap-door nest, which will certainly be found to belong to it, will prove distinct in some portion or detail of its structure. It is with great pleasure that I confer the name of Capt. Hutton upon this Spider, being iudebted to him for a large amount of materials for a Monograph on New-Zealand Spiders, and of which materials I hope to make full use before the expiration of any great length of time. Genus MIGAS, L. Koch. M I G A S DISTINCTUS, sp. n. (Plate LII. fig. 2.) Length of an immature female 4 | lines. Cephalothorax short, oblong-oval, a little longer than broad; anterior extremity broad and truncated, lateral marginal constrictions at the caput very slight; profile of caput rounded, and running off in a straight line from the thoracic fovea or indentation to the hinder extremity of the thorax ; the fovea curved, but not very long, the convexity of the curve being directed forwards. The other indentations are strong; on the upper part of the caput and on the ocular area and clypeus are a few strong bristly hairs of different lengths. The height of the clypeus is about equal to the length of the line formed by the fore-central pair of eyes. The eyes form a rather narrow area, whose transverse diameter is more than three times the length of the longitudinal diameter. All are small, the fore-laterals distinctly the largest, and each is separated from the fore-central on its side by an interval a little exceeding its diameter ; the fore-centrals are separated from each other by a diameter's interval, and are placed on a largish oval, black, slightly tuberculate spot. Each hind-lateral eye is separated from the fore-lateral on its side by an interval exceeding the diameter of the former; and each hind-central eye is flattened, of a shining pearly lustre, subtriangular, and contiguous to the lateral eye next to it. Taken in two transverse lines, the eyes form two curved rows, of which the anterior has its curve directed backwards and the posterior forwards. The legs are short, strong, paler than the cephalothorax, furnished with hairs, bristles, and spines ; the most noteworthy of the latter form a double row beneath each side of the tibiae and metatarsi of the first and second pairs ; the superior terminal claws |
