1879.] SPIDERS FROM NEW ZEALAND. 683 



palpal organs consist of a bulbous base, produced into an irregular, 

 tapering, somewhat twisted stem, ending in a rather obtuse point, 

 while in N. gilliesii the stem is much longer, curved, and drawn out 

 into a much finer point. 



A single example of this very interesting and distinct species was 

 received in 1879, from Capt. Hutton, by whom it was found at 

 Dunedin, New 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 distin- 

 guishing 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 indebted 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. 

 Migas distinctus, sp. n. (Plate LIT. fig. 2.) 



Length of an immature female 4^ lines. 



Cephalothorax short, oblong-oval, a little longer than broad ; an- 

 terior 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 in- 

 dentations 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 dia- 

 meter'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, fur- 

 nished 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
