Anuing the niaierial in our cabinets, received from time to 

 time through the generosity of Dr. Thos. Bancroft, there is a 

 large female trap-door spider with ova-sac and young, and 

 apparently a hitherto undescribed form. The species in 

 question evidently belongs to the sub-family Ctenizinse, but at 

 the same time differs from all Australian Ctenizid genera 

 known to me chiefly by the form of the labium and disposition 

 of the sternal sigilla. In the Austi-alian genera of the sub- 

 family Ctenizinffi, the lip is somewhat square, being short and 

 broad, while in the specimen before me it is rather longer than 

 broad, and coniform. Simon, in defining this sub-family, says 

 of the labium : " piece labiale libre ou moins separee du 

 sternum par une strie suturale et rarement un peu plus longue 

 que large " ^o. In respect of the sternal sigilla — the form 

 under review — appears to come nearest to that of the genus 

 Genynii, Simon — group Genijsea; — but differs therefrom by its 

 eyes. This will be seen at a glance if the reader will compare 

 Simon's figures and description^! with those given hereiinder 

 (figs. 28 and 31). Taking the facts herein briefly noted, in 

 addition to others that will occur to the student as he peruses 

 the description I give below, it appears to me that I have no 

 other alternative than to erect not only a new genus for its 

 reception, but also a new group name ; I therefore propose 

 Euoplos for the former, and Euoplo^a for the latter. 



Genus Euoplos,22 ijev. nov. 



Ceplinlothorax. — Longer than broad. Pars cepludica raised 

 (somewhat as in MissuJena, though not quite so high), sides 

 deeply impressed at junction of cephalic and thoracic
