Two distinct species of this genus M^ere obtained, the first 

 being represented by two examples, of which one is adult and 

 the other immature, whilst the second species is represented 

 by three specimens, none of which have reached the adult 

 stage. Both species are of striking appearance, and each is 

 undescribed. The spiders of this genus are noted for their 

 ■flattened abdomen, which latter are always more or less
