in front 1, and behind 1 spine, not 1, 1 both before and behind, 

 as is stated by Koch. They are easily distinguished from equally 

 large specimens of D. cognatus by the anterior central eyes being 

 rather smaller than the lateral eyes, and by the anterior row of eyes 

 being more curved forward. 



Of the still smaller D. umbratilis L. Koch ')> the cephalothorax 

 of which is only 2 — 3 millim. long, and the 4 th pair of legs 5—7'/, 

 millim., I have found two adult female specimens in Sweden, one 

 in the neighbourhood of Stockholm and one in Bohuslan. The 

 vulva in this species has the form of a tolerably large fovea, open 

 in front , bounded by a large, horseshoe -formed, or half- oval costa; 

 this fovea is divided into two by one longitudinal costa. There are 

 no spines under the tibiae of the 1 st pair in my specimens (which 

 have been identified by L. Koch himself). — This species is now for 

 the first time recorded as Swedish J ).

2) The following species of Drassus appear to be new to science: 

 Drassus occidentalis N. Cinereo-testaceus totus, abdornine tantum cinera- 



scenti-nigro , maculis parvis testaceis, per paria dispositis, in dorso; cephalotho- 

 rax longior quam patella + tibia pedum 4:ti paris , antice non multo angustatus ; 

 oculi seriei anticse sub-recta? aequales; pedes 4:ti paris cephalothorace c:a 2'/ 2 l° n - 

 giores, fernoribus posticis supra aculeis 1, 1, tibiis posticis supra non aculeatis. — 

 $ ad. Long. c:a 8y 2 millim. 



Cephalothorax 3 3 / 4 millim. longus, c:a 2 3 / 4 latus, antice non multo angu- 

 status, in dorso leviter convexus, parcius pubescens et pilosus, cum mandibulis, 

 palpis, pedibusque cinereo-testaceus. Oculi medii antici rotundi, vix minores quam 

 laterales antici, a margine clypei spatio minore distantes, quam quo a mediis po- 

 sticis distant, a lateralibus vero spatio paullo majore (vix diametnim oculi 

 aequanti) quam inter se. Oculi medii postici valde deplanati, ita ut limites eorum 

 ffigre distingui possint; certo situ saltern spatium inter eos non minus esse vide- 

 tur, quam inter medios anticos; oculi laterales postici a mediis posticis plus duplo 

 longius distant quam hi inter se, et fere duplo longius quam laterales inter se, 

 qui spatio diametrum oculi aequanti disjuncti sunt. Mandibular sat fortes, aeque 

 longae atque patella l:mi paris et ea, paullo crassiores, longitudine metatarsi + di- 

 midii tarsi pedum l:mi paris, sub-cylindratae , in dorso versus basin fortius con- 

 vexae. Palporum pars tibialis non dimidio longior quam latior, longitudine partis 

 tarsalis. Pedes breves et crassi, l:mi paris c:a 8y 2 , 2:di 7 millim. longi; 4:ti 

 paris 9y 2 millim. (patella cum tibia 3y 4 millim.), metatarso non longiore quam 

 tibia. l:mi et 2:di paris femora supra aculeos 1, 1, antice 1, postice 1 habent, 

 tibiae nullos aculeos; femora 3:tii et 4:ti paris supra 1, 1, antice 1 habent; tibiae 

 horum pedum supra non aculeati. Vulva satis insignis: prope rimam genitalem 

 adsunt costa? duse fortes, fuscae, fere C-formes, quae apicibus postice inter se ap- 

 propinquant, antice vero divaricant, ita ut aream fere semi-ovalem includant:
