The species here described by Westring is different from that 

 which is entitled to the Kochian specific name lanio, at least if the 

 form described and figured by Kocn as the chief form of the male 

 is to be considered as the type of the species. Th. lanio Wests. 

 was however probably known to Koch and by him confounded with 

 "X lanio:'' Fig. 1010 in Die Arachn., which represents the female, 

 appears in fact to me more like Westring's species than the right 

 X lanio C. Koch. The right X. lanio we take to be the spider, the 

 male of which C. Koch has figured fig. 1009; the "variety" of d* 

 represented in fig. 1011 seems to me on the contrary to be a male 

 A", bifasciatns. As regards fig. 1012, which Koch considers as also 

 a variety of X lanio, vid. infr. under Thorn, calcaratus Westr. 



X. lanio C. Koch, which is identical with X viaticus Ohl. ad 

 part. (Die Aran. d. Prov. Preuss., p. 113), according to specimens 

 communicated by Ohlert, and certainly also with Thorn, lateralis 

 Hahn — of which more hereafter — , and which I have received from 

 L. Koch under the name of X lanio, is but slightly larger than 

 X cristatus. The female greatly resembles that species, but the 

 male is easily distinguished both by its colour and by the different 

 form of the palpi. The bulbus has nearer the base two processes, 

 the first of which forms a fine, pointed, almost oppressed spine, 

 slightly curved and directed forwards (which spine may easily be 

 overlooked); the other is longer and stronger, has also the form of 



forti, parum acuminato, ad '/ 4 longitudinis laminae circiter pertinent!; procursu 

 inferiore in latere exteriore a basi ad apicem excavate-, postice et in angulo po- 

 steriore rotundato, apice antice emarginato, angulo anteriore producto et late 

 truncate-: margine antico igitur concavato. Lamina bulbi tuberculum conicum, in 

 margine mox ante apicem procursus lateralis partis tibialis situm, ostendit. Bul- 

 bus subtus ad basin spinis duabus fortibus, aeque fere longis armatus, quarum 

 posterior fere recta est, apice paullo tantum introrsum curvata, versus apicem com- 

 pressum sub-dilatata , altera apice acuminata, ad basin lateris anterioris et interioris 

 dente forti armata, introrsum et retro, versus spinam priorem, curvata; spinae 

 igitur digitis cheles cancris sub-similes. Pedes l:mi pans c:a 11 millim. longi, 

 2:di pans iis vix visibiliter breviores; femora et patellae 4 anteriora nigro-fusca, 

 reliqua internodia fusco-testacea, tibiae metatarsique 4 posteriores apice fusci, et 

 fusco-sub-maculati ; aculei subtus in tibiis anterioribus 8— 10 esse videntur, in duas 

 series ordinati. Abdomen nigro-fuscum , dorso limbo angustiore albicanti circum- 

 dato, vitta media ordinaria parum expressa, plerumque maculis 3 angustis transver- 

 sis utrinque maculaque antica et postica, his forma, minus definita, reprsesentata.
