much the more certain, as he has had the goodness to send me a 

 female specimen of his Micryphantes vittatus. Ohleet has also kindly 

 sent me several specimens of his Lin. terricola. — On L. terricola 

 C. Koch vid. supra, p. 57, L. tenebricola Weste. — Walckenaeb's 

 Argus guatemus cannot well be any other than Lin. dorsalis. — 

 That Micryph. laminatus C. Koch is a variety of this very variable 

 species appears probable to me, not only from the description of 

 the vulva, but also from the circumstance, that M. laminatus appears 

 to have spines on the legs, and thus to be a Linyphia: at least 

 Koch says of it: "die obereu Knie- und Schienbeinborsten dicker und 

 liinger als gewdhnlich." See also his figure, loc. cit. Micryph. lamina- 

 tus Ohl. (Aran. d. Prov. Preuss., p. 75) is a species unknown to 

 me. — In Germany I found L. dorsalis common at Travemunde.

According to Walckenaee (Ins. Apt., II, p. 265) the spider, 

 which he, in his Tabl. d. Aran., p. 76, has called Theridium alveo- 

 lus, is the same as L. longidens Reuss; as however the species is 

 there in no way described, the specific name alveolus can have no 

 right of priority in preference to that subsequently imposed by Reuss. 

 — Micryphantes tesselatus C. Koch (Die Arachn., Ill, p. 86, fig. 234), 

 which Walckenaee includes among the synonyms of this spider, does 

 not belong to the genus Tapinopa. — Prof. Canesteini has himself 

 kindly sent me a specimen of his LAnyphia lithobia.
