(lomen ovate, arched, not overhangino- base of cephalothorax, finely pilose 

 pale yellow, almost white: no design (jh superior surface. Epigynum simple, 

 with two elliptical discs. 



'ilie species described aljove will, no doul)t, idtiniatclv have to !)e jilaced 

 in a new genus, as both sexes disjilay certain i)eculiarities. In the male, for 

 instance, the labium should be longer; its tarsal segment is not strictly in 

 accord with other species of the genus. Then in respect of the female the 

 sternum is rather narrow, and the armature of the legs too pronounced, the 

 spines being not only longer, but unusuall}- numerous. Type, I. 115,54. 



CHIRACANTHIUM GILVUM L. Koch (L.fl.I.) 

 Four immature examples of what is, in rill probabilitv, this species. 



DORYMETAECUS gen. nov. 



Cephalothorax obo\'ate, arched, broad, narrow in front. Pars cephalica 

 sloping forward, not hig-Jier than thoracic segment; segmental groo\'e faintly 

 distinct; clypeus narrow. Pars thoracica broad, radial grooves defined: median 

 stria short but well defined. Eyes in two rows of four each ; eves of rear row 

 larger, both rows close together. I^egs long, strong ; tibiae and meta-tarsi 

 i and ii armed with long and strong spines; legs i and ii stoutest; relative 

 lengths, 4, 1, 2, ,1. Pal])i short. Falces weak. Maxillae short, stout, some- 

 what constricted near base, apices inclined inwards. Labium short, broadest 

 at base, a]iex rounded. Sternum cordate, terminating obtusely between 

 fourth pair of coxae. Abdomen o\-ate. Spinnerets short biarticulate ; superior 

 pair slightly the longer, c}'lindrical, apical segment short ; inferior pair stout, 

 coniform, apical segment minute. 



This genus would appear to fall between groups Miturgeae and Zorae. 

 The meta-tarsi and tarsi are devoid of scopula, but the tibial and metatarsal 

 segments of legs i and ii are heavily and powerfully s]Mned. The cephalo- 

 thorax is broad, obovate and well arched, and the lateral margins reflexed : 

 the segmental and radial grooves are faintlv distinct, and the thoracic stria 

 short, but well defined. The e}-es in two rows of four each, those constituting 

 the ])osterior series being the larger. The maxillae are rather short, stout, and 

 inclined inwards, and the labium short, broad at the base and uniform. The 

 sternuiu is broad, arched, cordate, and terminates in a scjmewhat acute point 

 between the fourth coxae. The superior spinnerets are fine, short, c\-lindrical, 

 and biarticulate; the inferior ])air are also biarticulate, and are short, stout, 

 and coniform.
