Show 1893.] SPIDERS F R O M ST. YINCENT, W E S T INDIES. 693 Legs, 3 and $, 4, 3, 1, 2. The femur of the fourth leg is enlarged, especially in the male. The cephalothorax is narrow and long-twice as long as wide. The sides are nearly parallel until the posterior quarter of the thoracic part, where the cephalothorax grows abruptly narrower. The cephalic part is on a higher plane than the thoracic and has its sides inclined inwards. The thoracic part is rounded in its anterior three-fourths, the posterior end, where it joins the abdomen, being flattened. There is a constriction at a little distance behind the dorsal eyes. The quadrangle of the eyes is nearly equally wide and long, is wider behind than in front, and occupies about one-third of the cephalothorax. The first row of eyes is strongly bent; the eyes are close together, the middle being twice and a half as large as the lateral. The second row is nearer the first than the third row. The dorsal eyes are larger than the lateral and form a row which is as wide as the cephalothorax at that place. The clypeus is narrow. The labium is wider than long. The sternum is long and narrow. The abdomen is very long and has a constriction in the middle; it is narrowest in front, tapering gradually toward the anterior end. The integument of the anterior part is slightly hardened above, on the sides, and below. The falces are moderately stout and long and are vertical. The cephalic plate and the anterior thoracic part are yellow, with the e\ es on black spots; there are some white hairs on the anterior part; between the dorsal eyes are two fine dark fines; the rest of the upper surface is brown, darkening toward the posterior end, with a thin covering of white hairs, and having white bands around the two constrictions. The spinnerets are light-coloured. The legs are w-hite or light brown, excepting the femoral joints of the third and fourth pairs, which are rufous. The falces are reddish. The palpi, mouth-parts, and coxae are white. The sternum and venter are yellowish, the venter being blotched with white. KEYSERLINGELLA MINUTA, sp. nov. 2 • Length 3. Length of cephalothorax 1-3; width of cephalothorax f8. Legs 4,3,1,2, all slender. The cephalothorax is rather short, with a slight constriction just behind the dorsal eyes. The cephalic part is flat, and is on a higher plane than the thoracic which is rounded, and falls quite steeply from the ridge behind the constriction. The sides are parallel. The abdomen is rounded, and is widest behind the middle and narrow at both ends. The clypeus is narrow. _ The quadrangle of the eyes is one-fourth wider than long, is wider behind than in front, and occupies about one-half of the cephalothorax. The first row is curved; the eyes are close together, the middle twice as large as the lateral. The second row is halfway between the first and the third. The dorsal eyes are larger than the lateral and are on the sides of the head. The sternum is wide and is truncated |
