TRAP- DOOR SPIDERS. - »8 



tlie same point, but do not reach nearly, in fact not much more 

 than half way, to the eyes. The clypeus is of a clear brown-yellow 

 colour also, and on either side of it (extending from each fore 

 lateral eye), is an irregular patch of the same. The ocular region 

 and clypeus are furnished with a few strongish black bristles, and the 

 three yellow stripes above mentioned have a few more, those on 

 the central stripe being the longest and strongest, and disposed in 

 a single longitudinal row. 



The Eyes, eight in number, are seated on a transverse oval 

 eminence, and form a rectangular figure, whose transverse diameter 

 is double the length of its longitudinal diameter : their relative 

 position is similar to that of Cteniza, but in the present species 

 they are smaller than in C. fodiens : those of the hind central pair 

 are the smallest of the eight, and each is very nearly contiguous 

 to the hind lateral on its side ; the interval between those of each 

 lateral pair is small ; the space between the two central eyes of the 

 eight is equal to an eye's diameter, and each of these is separated 

 from the hind central and fore lateral nearest to it by a similar 

 interval. The Legs are strong, moderately long, their relative 

 length 4, 1, 3, 2 ?, but little diflEerence is observable between 1, 3, 

 and 2 ; they are furnished with hairs, bristles, and a few, not very 

 strong, spines ; each tarsus terminates with three curved claws, the 

 two superior ones much the longest and strongest, and have a few 

 small teeth near their base inside. 



The Palpi are strong and similar in colour and armature to the 

 legs ; each is terminated with a curved black claw. 



Falces strong, prominent, and rounded in the profile line ; they 

 are furnished with hairs, bristles, and strong tooth-like spines ; the 

 four strongest of these latter form a transverse row at the inner 

 extremity of each ; besides these there is a row of short tooth- 

 like spines on the inner margin of the furrow on the underside of 

 each falx, in which the fang lies concealed when at rest. The 

 Maxill(B are strong, with a small angular prominence at their inner 

 extremities (when looked at from beneath), and each has three to 

 four small dark-coloured teeth in a short, straight, obliquely trans- 

 verse row at the base on the inner side. Labium broad but short, 

 its breadth is double its height, and the upper corners are roimded 

 off. The Sternum is of a somewhat pentagonal form. 



Abdomen ritther elongate oval, tolerably, but not excessively, 

 convex above ; it is of a dull yellowish whitey-brown colour 

 marked and mottled above with dark chestnut brown ; the mark- 

 ings are rather irregular, but a general disposition in the form of
