M. E. broader in front tlian behind, the 

 P. S. E. nearly as large as the A. S. E. The 

 cephalothorax and abdomen with the usual 

 clavate and spatulate hairs. Legs short and 

 stout, the tibia I concave on outer margin 

 near base; all femora with one spine above, 

 femur I with one spine in front, tibia with 

 two pairs beneath, metatarsus witli three 

 pairs beneath and one on eacli side. The 

 epigynum consists of three cavities, or 

 rather a large cavity divided into three 

 portions by a broad plate; the two lateral 

 cavities are somewhat elliptical, broader 

 behind and contain in the posterior part an 

 almost black, blunt projection, beneath and 

 in front of which is a reddish similar one; 

 the anterior cavity is broadly triangular with 

 rounded angles, and contains, projecting 

 from beneath the posterior border, a broad, 

 rounded, dark body; behind are the two 

 small holes as usual. 



Tliree specimens, Itliacn, N. Y., 

 beneath dead leaves in qnite marshy 

 ground. This species, which I forinerly 

 regarded as O. georgiana (Cayuga 

 Lake Spiders), is quite distinct by its 

 peculiar epigynum, by its mottled legs, 

 and by the two white spots above on 

 the cephalothorax. 



Oxyptila pacijica nov. sp. — Length 4 mm. 

 Cephalothorax reddish yellow, paler above, 

 white behind; sides somewhat mottled with 

 brown, almost forming a superior stripe 

 which is terminated behind by a black spot, 

 brown and white markings around eyes; legs 

 pale yellow, femora spotted with brown, 

 patellae III and IV with a black spot in 

 front, a dark band at tip of femur and at base 

 of tibia IV; sternum and coxae pale, a brown 

 spot on each coxa and on each trochanter. 

 Abdomen pale, with some silvery spots 

 above and two black spots on front margin, 

 behind two or three irregular interrupted 

 brown bands; venter pale, with a few brown 



spots. Eyes about as usual, the M. E. equal, 

 S. E. nearly equal. Cephalothorax and 

 abdomen with two sizes of clavate hairs, the 

 larger size less numerous than the much 

 smaller ones. Legs short, femora with one 

 spine above, femur I with one in front, tibia 

 with two pairs below, metatarsus with three 

 pairs below and one in front. The epigynum 

 consists of a narrow transverse cavity 

 bounded behind by a deeply concave ridge, 

 the sides continued and enlarged posteriorly, 

 the anterior lobe some distance in front, two 

 transverse lines between it and the posterior 

 ridge; behind are the two small holes, less 

 than their diameter apart. 



One female and one young male from 

 Olympia. Washington, collected by 

 Mr. Trevor Kincaid. 



Oxypliln ne-'adensis Keys. — This appears 

 to be a very good species, differing from all 

 the others by having two spines on each side 

 of metatarsus I, in that the A. M. E. are a 

 little larger than the P. S. E., and in the 

 different epigynum. The legs are mottled 

 and femur I has three or four spines in front. 

 I have never seen it. 



Oxvptila fioridana nov. sp. — Length 

 4 mm. Cephalothorax reddish yellow, 

 almost wholly covered with black markings, 

 eyes surrounded by yellow, three oblong 

 yellowish spots above and two on each side 

 lower down, mandibles black with a yellow 

 spot in the middle, femora pale at base, with 

 black patches, black at tip, tibia and patella 

 almost wholly black, metatarsus black 

 beneath and in front, sternum nearly all 

 black, coxae blackish, abdomen black with 

 white dots, a large white spot on each ante- 

 rior side, spinnerets white; whole body with 

 a very fine scattered, glistening, silvery 

 pubescence. Eyes about as usual, cephalo- 

 thorax and abdomen with large and many 

 small clavate hairs; femora with one spine 

 above, femur I with one in front, two pairs 

 under tibia, three pairs under metatarsus,
