Two specimens of what appear to be examples of this 

 genus are included in the collection — one, an immature female, 

 and which it is not possible to determine specifically with 

 safety ; and the other a mature male. Both examples are from 

 the same locality, and may possibly be one and the same 

 species. Only two forms of Echemus^ ( ?) have been described 

 from Australia, viz., E. (?) ( DrassusJ dilutus, L. Koch, from 

 Rockhampton, Northern Queensland, and E. (?) {D.J griseaiSj 

 L. Koch., "Neuholland." Both of these were females, and 

 the first-named was immature. In the absence of an adult 

 female, one cannot say with exactitude whether the mature 

 male in this collection is a new species or whether it may not 

 be the unknown male form of E. (D.) griseiis, but to that 

 species for the present I associate it, and hereunder give a 

 description.
