1901.] SPIJDEBS PROM JAMAICA. 11 



Saitis defloccattjs, n. sp. (Plate III. figs. 5, 5 a.) 



2 • Length 4*5 inrn. Legs 4 3 12, all slender. The first is 

 almost as long as the third and fourth, but the second is distinctly- 

 shorter, the first exceeding it by the length of the tarsus. 



The cephalothorax is high at the dorsal eyes, from which point 

 it is strongly inclined in both directions. The upper surface is 

 rounded. The sides are widest at the dorsal eyes, narrowing 

 before and behind, and widening again at the front end. The 

 anterior eyes are close together, the middle being nearly twice as 

 large as the lateral, and form a row which is a little curved down- 

 ward. The clypeus is narrow. The quadrangle of the eyes is 

 wider in front than behind, is one-fourth wider than long, and 

 occupies nearly one-half of the cephalothorax. 



Under alcohol the spider appears as in Mr. Emerton's drawing, 

 but when dry the cephalothorax is seen to be covered with light, 

 golden, iridescent scales, excepting a central white band on the 

 thoracic part. The abdomen has a white band around the front 

 end, but is otherwise covered with silvery iridescent scales, there 

 being some wavy black lines and spots on the posterior part of the 

 dorsum. The legs and palpi are pale brown, ringed with darker 

 brown. The falces are small and brown. 



"We have one female from Kingston. 



Pellexes traxslatus, n. sp. (Plate III. figs. 6-6 c.) 



cJ . Length 4*5 mm. Legs 3 4 12. The first and second are 

 considerably shorter than the third and fourth, and the third is 

 longer than the fourth by the length of the tarsus ; first stoutest. 

 The cephalothorax is moderately high. The cephalic plate 

 slants forward ; the upper surface and sides are normal for the 

 genus. The anterior legs are close together in a straight row ; 

 the middle are not twice as large as the lateral. The quad- 

 rangle is a little wider behind, and nearly one-fourth wider than 

 long. The second row is halfway between the outer two, and 

 the third row is as wide as the cephalothorax at that place. One 

 specimen is a good deal rubbed, and under alcohol it appears as in 

 Mr. Emerton's drawing ; but when dry, the upper surface of the 

 cephalic part is covered with fawn-coloured hairs, and on each 

 side of the head and thorax there is a wide band of white hairs. 

 These bands are on the lower edge, and unite behind with a wide 

 white band that runs back, on each side, from just behind the 

 dorsal eye, down the posterior slope of the thorax. The space 

 between the two white bands on the posterior slope of the thorax 

 is dark-coloured. The lower white bands, as they pass forward, 

 do not unite in front on the clypeus, but turn down and end in a 

 narrow point on the front face of each falx. The space thus left, 

 under the middle eyes of the first row, is dark-coloured. There 

 are a very few red hairs around the first row of eyes. The abdo- 

 men is dark above, nearly surrounded by a wide white hand which 

 passes very far down on the sides and stops at the spinnerets. 

 There is a central longitudinal white hand from base to apev of
