rior end. Two circular eyes, separated from each other by their 

 diameter, are situated on a transversely oval field. This field is 

 quite flat and it is not probable that in life it had the shape of a 

 tubercle. The chelicera? are scarcely visible. The pedipalpi are

short. The legs are very long. Those of the second pair are 

 broken off and even in the left leg, which is more complete than 

 the corresponding right leg, it is not possible to determine how 

 much of the leg is missing. The right first leg is complete except 

 for the tibia, the right third leg complete except for a piece of 

 the metatarsus and the right fourth leg complete except for a 

 short piece on each side of the tarso-metatarsal joint. The legs of 

 the left side are complete except for the end of the second leg. 

 Measurements are difiicult owing to the curvature of the joints 

 and are therefore only approximate. First leg, femur — 4.7 mm., 

 tibia with i)atella — 4.6 mm., metatarsus with tarsus — 12.6 mm., 

 total — 21.9 mm. ; Second leg. femur 8.0 mm., tibia with metatarsus 

 and tarsus (incomplete) — 17.0 mm., total (incomplete) 25.0 mm.;
