217 — 222) afresli described. C^oncerniiig the type-specimens 

 for the other species Mr. Simon states them to be destroyed 

 and adds to this eommunication that the descriptions pu- 

 blished by Nicolet are too incomplete for recognizing the 

 species. Subsequently a new species — D. limhata — has been 

 described by Simon in Arachnides recueilUs a la Terre de Fen 

 par M. Carlos Bachhausen (2^™« Mém.) (in An. del Mus. Na- 

 cional de Buenos Aires T. V. 189(), p. 141 — 45) and in my 

 paper Coutrihution to the Jcnoidedge of the Spider Fauna of 

 the Magellan Tcrritories (in Svenska Expeditionen till Ma- 

 gellansländerna. Bd II, N:o 10) I described a species D. 

 hllineata thereto induced by the incomplete and short de- 

 scriptions \ve have of D. macrophthalma Nic. and limbata 

 Sim. and by the difficnlty to form an absolutely accurate idea 

 of the strnctnre of the exteriör genital organs only from a 

 short description withont lignres. In fact this species — 

 according to a eommunication by Mr. Simon — for the pre- 

 sent must be regarded as probably identical with D. limbata 

 Sim. In the collection of Mr. P. Dusen there are three species, 

 which no doubt are to be regarded as new to science, and two 

 of which are of a special interest b}^ being represented even 

 by males, hitherto not known of any species. By these finds 

 our knowledge of this species has been a little enlarged. 



The cephalothorax is oval, tapering towards the front, 

 which is comparatively high. The pars cephalica is high 

 convex, more or less distinctly separated from the much lower 

 pars thoracica. In the middle of this is a transverse, nearly 

 oval depression. The colour of the cephalothorax is more or 

 less påle yellow-brown and on the sides are blackish bands, 

 which sometimes are nearly effaced. The both rows of eyes 

 are recurved and the lateral eyes are separated by an interval 

 about twice as long as their diameter. The anterior middle- 

 eyes are always much smaller than the others and the inter- 

 vals, which are equal in length, are not broader than the 

 diameter of the anterior middle-eyes. The elypeus is narrow, 

 never higher than the diameter of the lateral anterior eyes. 

 The cheliceres are by the female short, about twice as long, 

 as broad but by the male much longer. The claw-furrow 

 has by both sexes at the outer margin three \evj strong teeth, 

 at the inner margin four. On the outside of the outer teeth 

 there is a row of about nine long stilf hairs. The maxilhe
