Remarks. This species undoubtedly belongs in the genus 
Thaumasia, as defined by Simon and Cambridge but resembles 
Dolomedes in general appearance. The armature of the legs and 
lower margin of the furrow of the chelicera and the arrangement 
of the eyes and suture of the superior lorum of the pedicle is char- 
acteristic of the genus and quite sufficient for identification. This 
species is considerably larger than most of the described members 
of the genus and outside the normal range, other species being con- 
fined to subtropical or tropical regions.
