Cambridge. — On the Spiders of New Zealand. 201 



Cephalo-thorax broad oval, slightly squared (or truncate) at each end, 

 depressed above, with but slight hinder slope, and little lateral compression 

 forwards ; the normal furrows and indentations are strongly marked ; that 

 indicating the junction of the caput and thoracic segments is large, deep, and 

 of a circular form . It is of a clear and uniform yellow colour, with some marginal 

 rows of short, and not very strong, dark hairs ; a few of the same are also on 

 the hinder slope, and a single row runs from between the eyes of the hind 

 central pair to the thoracic junction. 



The Eyes are on a very slight eminence close to the fore margin of the 

 caput (the height of the clypeus being equal to the diameter of one of the four 

 central eyes), and are in a position common to numbers of the Theraphosides. 

 They are in two curved rows, or perhaps they may be better described as 

 follows : two round, dark-coloured ones occupy the middle of the fore part 

 of the slight eminence mentioned ; these are separated by an interval of rather 

 less than the diameter of one of them, and on either side is a group of three 

 other eyes of a pearl-white colour, in a triangular form ; but though rather 

 close to the round eye on its side, and to each other, they are none of them 

 contiguous with the other. Looking at the eyes as in two transverse rows, the 

 two hind centrals are wide apart, the interval being nearly equal to the 

 length of the line formed by those of the fore central pair ; the form of the 

 hind centrals is also somewhat quadrate ; that of the eyes of the lateral pairs 

 is oval. The fore laterals are largest, obliquely situated, and each is separated, 

 from the fore central nearest to it by an interval equal to that which divides 

 it from the hind lateral on its side, which is also oblique, and very near to, 

 but not contiguous with, the hind central nearest to it. 



The Legs are strong, and moderately long, but not greatly differing in 

 length — apparently their relative length is 4, 3, 1, 2. Those of the first pair 

 are much the strongest, and have the tibise and metatarsi inordinately 

 developed ; the former are of large size, and somewhat oval, tumid form, and 

 are armed with numerous not very long, but strong, bluntish-pointed black 

 spines beneath the fore extremity, and on the inner side. The metatarsi are 

 strongly bent downwards, and have a somewhat angular enlargement beneath 

 their fore extremity. The legs, generally, are armed with spines, and furnished 

 pretty thickly with hairs ; each tarsus ends with three claws, but there is no 

 scopula beneath them, which negative character appears to be the only good 

 distinction from the genus Diplura^ Koch. The colour of the foremost pair is 

 a deep, rich reddish, chestnut-brown ; the rest are of a greenish yellow-brown, 

 the different joints, except the tai'si and metatarsi, being longitudinally banded 

 with a darker hue. 



The Palpi are moderate in length and strength ; they are of a greenish 

 yellow-brown colour, and furnished with long hairs chiefly on the radial
