 of the major teeth. Tibia of palp without papillae and without spines, studded ventrally with strong 

 cylindrical bristles ; patella uiispined, bearing above and below short and long bristles, and above also 

 some fork-shaped hairs ; femur bristly below. Protarsus of fourth leg with four or five pairs of spines, 

 on the inner side beneath no conspicuous long row of strong spiniform bristles.

 Datames striatus, Putnam, Proc. Davenport Acad. Sci. iii. p. 255 (1883) 3 . 



Colour of carapace and mandibles yellowish-red, the former lightly infuscate ; tergal plates of abdomen dark, 

 sternal plates yellow, lateral membrane violet-grey dorsally ; palpi uniformly yellowish-red in female, the 

 protarsus dark reddish-brown in male ; legs uniformly coloured, except the fourth pair in the male, which 



are darker in the middle of their length. 



(3 . Upper jaw of mandible straight, slightly expanded in the middle, its inner side grooved throughout its 

 length, in the basal third of its lower edge forked, hollowed out into a longitudinally elliptical area into 

 which the enlarged tooth of the lower jaw fits, the cheek armed with two larger and two or three smaller 

 teeth on each side ; lower jaw with one large proximal tooth and two smaller distal teeth, the proximal 

 of these two rising from the base of the larger tooth in front, on the inner side of the large tooth arises 

 a tooth-like tubercle. Tibia of the palp without papillae and true spines, but studded externally with 

 numerous cylindrical bristles, covered dorsally only with fine bristles ; patella armed below in the basal 

 half with about six spines arranged irregularly in two rows, and beset, in addition, with cylindrical and 

 other bristles ; bearing short and long bristles above ; femur with some spines at the distal end of the 

 lower surface. Protarsus of fourth leg with four or five pairs of spiniform setae beneath, and on the 

 inner border with some additional spiniform setae. 



5 . Upper fang of mandible normally toothed and normally shaped, with two or three small teeth rising from 

 the base of the principal teeth. Palpi as in the male, but the femur and patella armed beneath with 

 spiniform setae instead of with spines. Protarsus of the legs of fourth pair armed beneath with four or 

 five pairs of spines, without conspicuous longitudinal row of nine equally strong spiniform setae on the 



inner edge below.
