Under this species Westring, though with an interrogation, 

 takes up Drassus ci.ne.reus Hahn ') and C. Koch 2 ): as however Koch 

 expressly states, that in D. cinereus the cephalothorax has no bl ck 

 border, I have not ventured to receive the specific name cinereus as 

 belonging to the spider now in question. See also D. gracilis Westr., 

 next following. 



(Pag 366.) 4. D. gracilis [= Drassus gracilis (Westr.) 1861 J. 



Westring's type-specimen (a dried and considerably injured ? 

 jun.) is the only one I have seen of this species. The eye-area is 

 not fully twice as broad as it is long. The distance between the 

 anterior central eyes is not at all, that between the posterior central 

 eyes scarcely perceptibly, greater than the eye's diameter; between 

 the anterior lateral and central eyes the distance is less than half 

 an eye's diameter. The cephalothorax is shorter than patella + tibia 

 of the 4 th pair of legs, but not shorter than these joints together of 

 the 1 st pair. 



May not this species be identical with Drassus cinereus Hahn 

 et C. Koch (see preceding species, D. pubesce?is Westr.), which, like 

 1). gracilis, is without black border to the cephalothorax?
