lamella, equally dilated on both sides; the edge of this lamella is 

 rounded, and denticulated anteriorly Avith about six small teeth, of 

 which the three anterior are larger than the others, which are very 

 small. Somewhat below and in front of this process are two other 

 lamellar processes with obtuse apices, close to each other, of which 

 the superior is very broad at its base, narrowing towards the apex ; 

 the inferior, which appears to be longer, is almost straight and linear. 

 In front, above and at the outer side, issues a strong, forward di- 

 rected, arched, brown lamellar process, tapering towards the obtuse 

 apex. The legs are yellowish brown ; the thighs more or less dis- 

 tinctly darker at the apex, the patella? also somewhat darker at the 

 apex; the tibise and metatarsi have each three dark rings; the tarsi 

 are blackish at the apex. The tibiae of the second pair of legs are 

 very slightly curved outwards, evidently thickened on the inner side, 

 towards the apex, and here armed with some spines, which are 

 stronger than the other spines of the tibia: two of these spines are 

 placed on very low tubercles. The coxa? of the first pair are, on the 

 under side, armed with a slightly curved obtuse spine. Abdomen 

 ovate, olive brown, with long whitish hairs; it has along the back a 

 whitish marking, which consists of two short slightly diverging lines 

 near the anterior margin, forming almost a narrow /\, two such lines, 

 more strongly diverging, forming a broader /\ immediately behind 

 them, and followed by a narrower whitish, geminated band tapering 

 towards the anus, and composed of two or three pairs of small, almost 

 parallel, whitish lines. The belly has a large, oblong, yellowish spot 

 in the middle, and probably also smaller yellowish spots towards the 

 sides, especially behind. 



Length of the body, 5 millim.; length of cephalothorax, 2.5 millim., 

 its breadth, 2 millim.; length of legs: first pair, 10.5 millim.; second, 

 8.5 millim.; third, 5.5 milhm.; fourth, 8 millim.; length of patella 

 and tibia of the fourth pair, 2.5 millim. ; of tibia, 1.75 milhm. 



A single adult male specimen of this spider was captured on 

 Square Island, Labrador, in July. The specimen is in a very bad 

 state of preservation, and its color could not therefore be so accu- 

 rately described as I should have wished. It may, however, readily be 

 distinguished from the very closely allied European species Epeira 

 ceropegia Walck. and E. Victoria Thor., not only by its smaller size, 

 but also by some differences in the organs of copulation. The process 

 on the outer side of the bulbus genitalis, for instance, has the denticu- 

 lated apex emarginate in E. ceropegia 6 . truncate in E. Victoria d",
