and a half times the diameter of an eye; innei- edges of 

 anterior lateral and posterior median practically in the same 

 line; distance between anterior and posterior laterals quite 

 one and a half times that between an anterior lateral and 

 anterior median. 



Pe dip alps. — Patella slightly longer than that of the fii'st 

 leg, shorter than the tibia of that leg or of the palp. Tibia 

 and tarsus together considerably shorter than the carapace. 



Legs. — All the tarsi scopulate below; no trace of a scopula 

 on the metatarsi. Tarsus I with a single spine on its anterior 

 side and four on the posterior side (II wanting in the speci- 

 men) ; III with numerous spines in a continuous band on both 

 anterior and posterior sides; IV with numerous spines on both 

 sides, especially anteriorly. Metatarsus I with strong spines 

 below, both over the median area and at the sides. Tibia I 

 considerably shorter than the metatarsus, with strong spines 

 below and at the sides ; III with a few short spines and 

 spinules on or near the distal edge on both anterior and 

 posterior sides superiorly. Patella I with two spines at the 

 apex inferiorly and one on the lower surface; III with an 

 anterior band of spines, but no distal patch of spinules above 

 apart from those belonging to that band ; IV with an anterior 

 patch of spinules extending about three-fifths of the length of 

 the anterior side. Paired claws of tarsus of fourth leg with a 

 basal comb of four large teeth, distal to which is a very small 

 tooth, and on the posterior claw one or two minute teeth occur 

 on the proximal side of the comb.

 of same 10 mm., length of tibia of palp measured from above

This species is distinct from S. nigellus Poc. (Ann. Mag.
