rapidly nearer the extremity, which is directed forwards and some- 

 what upwards, with the slender apex itself obliquely truncated and 

 finely notched or crenulated. The lamina is oviform , somewhat lon- 

 ger than the patellar and tibial joints together, quite as long as the 

 mandibles and at least as broad as these last. The bulbus is short, 

 almost truncated and broad at the extremity, where it has on the 

 under side a little, short, crooked hook; from the under side proceeds 

 in a forward and inward direction a long, fine, black spine, which 

 bends circularly before the bulbus, and the point of which, accom- 

 panied by a pale membranous appendage, is often seen to project 

 from the outer side of the apex of the bulbus. The female's vulva 

 is formed by a large, deep, semi- elliptic, black or brown fovea, open 

 behind. Westring's statement, that cf of this species has no such 

 "shield" on the back of the abdomen, as is seen in the males of 

 certain species of Drassus and Melanophora, e. g. D. scutulatus, M. 

 Petiverii (subterranea) etc., is not correct: the shield is present, but in 

 completely uninjured (living or dried) specimens it is entirely con- 

 cealed by hair; in specimens preserved in spirits, as also in such 

 specimens as have had the hair rubbed off in that part, it may im- 

 mediately be seen. 



I possess two female specimens of a Swedish Drassus, which 

 very closely resembles D. 4-punctatus, but is perhaps a separate spe- 

 cies, and to which, in order to draw attention to it, I give a separate 

 name: it may be called D. gotlandicus. It appears to differ from 

 D. 4-punctatus almost only in the appearance of the vulva, which 

 is quite different from that of D. 4-punctatus: in the posterior half 

 of a little oblong, light- brown spot, bounded behind by the rima 

 genitalis, there are two small, dark brown, oppositely [( )] curved, 

 c- or somewhat ^-formed costse, and a little in front of them a very 

 small ring or fovea, from which a fine costa or line seems to extend 

 backward between the two first- mentioned costae. The cephalothorax is 

 5 millim. , the 4 th pair of legs 14'/ 2 millim. long; the metatarsi of 

 this pair are but triflingly longer than the tibiae. In other respects 

 I). gotlandicus is so like D. 4-punctatus, that Westring's and L. 

 Koch's descriptions of the latter (even as regards the spine-arma- 

 ture) are word for word applicable to the former. It was found in 

 the summer of 1868 by my wife in a house at Wisby in Gotland. 

 I have since received specimens of the same from Miinster in West- 

 phalia from Mr P. Karsch.
