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 
ofa circular form. Itis ofa 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 Zyes 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 adm 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 tibie 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 down wards, 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 tarsi 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
