 Blackw. — I have lately received of Dr F. Sodkrlund a male spe- 

 cimen of a Dysdera from the island of Mallorca, which is very clo- 

 sely allied to D. maurmia n. and D. crocota C. Koch, especially the 

 latter, but which appears to he different from both. The colour of 

 this species, which I call D. baharica, is about the same as in D. 

 crocota, D. maurusia, D. Cambridgii and D. riibicunda (on these 

 species see above, pp. 466—468): cephalothorax and sternum are 

 rust-coloured, with a fine black lateral border, the oral apparatus 

 also rust-coloured, palpi and legs of a rusty yellow colour, abdomen 

 greyish yellow. Cephalothorax and sternum are finely rugulose, as 

 in the above-mentioned species. The anterior eyes are separated by 

 an interval about as great as the diameter of one of these eyes. 

 The body is about 10 millim. long, cephalothorax 4 millim. (= pa- 

 tella + tibia 2:di paris), its greatest breadth 3 millim. The clypeus 

 is 2 millim. broad; the mandibles, which are as long as the tibiae 

 of the 4:th pair, are little more than 2 millim. long, scarcely lon- 

 ger than the clypeus is broad; above they are provided with scarce 

 hairs and indistinctly transversely striated. The l:st pair of legs 

 are 13 millim., their tibia 2V 2 millim. long; the legs are destitute 

 of spines, with exception of the thighs of the 4:th pair, which have 

 a small spine at the base, above, and the tibiae and metatarsi of the 

 two posterior pairs, which are armed with several spines. The geni- 

 tal bulb is of the same general form as in D. crocota, strongly 

 tapering or depressed on the anterior side somewhat above the mid- 

 dle, where the basal part passes into the "shaft", and forms at this 

 point, on the inner side, a prominent, obtuse angle or coarse pro- 



1 millim. longae, tibias l:mi paris longitudine aequantes. Palpi et pedes ferrugi- 

 neo-flavi, pedes l:mi paris 5 millim. longi; tibiae et metatarsi pedum 3:tii et 4:ti 

 parts aculeis armati, femora omnia, ut pedes prsetera, inermia. Bulbns genitalis 

 magnus, valde longus, ex parte basali inaequali, inverse ovata fere, et scapo sat 

 longo constans: pars basalis in utroque latere versus medium incrassata est et 

 paullo infra, in latere exteriore, hamo forti, sursum curvato, acuto, obscuro ar- 

 mata, deinde in scapnm satis sequaliter transiens; scapus praeterea sat sequalis et 

 angustus, cum parte basali angulum valde obtusum formans, anteriora versus et 

 intus directus; in apice sub-dilatato scapus limbum tenuem ostendit, qui, ex an- 

 gulo apicis exteriore oriens et ad latus ejus exterius productus, hie in latus ante- 

 rius scapi oblique ascendit et ad latus ejus exterius desinit. Abdomen obscure 

 cinereo-testaceum , ventre pallidiore. 



Marem unicum, in insula Ophiusa (Formentera) a D:re F. Soderlund cap- 

 tum , possideo.
