measurements are specified below. A series of 20 measurements involv- 
ing various components of the spider were made for each specimen. 
The most diagnostic of these measurements are recorded for compari- 
son in Table i. 
The posterior median eyes (PME) and the posterior lateral eyes 
(PLE), which form two rows in the Lycosidae, are referred to in this

paper as the posterior ocular quadrangle (POQ). The measurement 
of the POQ is illustrated in Text Figure i. 
The distance A is the width of the anterior row of the POQ, the 
distance B is the length of the POQ, and the distance C is the width 
of the posterior row of the POQ. The length of the carapace was 
measured as the distance from the line tangent to the posterior-most 
part of the carapace to the line tangent to the anterior-most part of the 
AME. Total length was measured from the most anterior part of 
the AME to the tip of the anal tubercle, when this structure was 
visible, or to the posterior tip of the abdomen. When the specimen 
was stretched so that the lorum of the pedicle was visible (an abnormal 
attitude in the living spider), the abdomen was measured and the 
length of the carapace was added as the distance from the anterior
