442 Mr. R. I. Pocock on Arachnida from the 



Genus SPARASSUS, Walck. 



Sparassus croceiceps, sp. n. (PI. XIII. fig. 5.) 



Colour. Carapace and legs a bright ochre-yellow, covered 

 with yellow hairs ; scopulse dark grey ; mandible ferruginous ; 

 abdomen testaceous, its upperside studded with ill-defined 

 fuscous patches of hair, some of which form a distinct double 

 series in the middle line. 



Carapace high, strongly convex, longer than broad, its 

 length equal to protarsus of second, patella and tibia of third 

 leg and to palpus, its width equal to protarsus of first leg. 

 Eyes of anterior line slightly recurved, subequal, subequally 

 spaced, the medians a little nearer each other than either 

 is to its lateral, about a diameter apart ; eyes of posterior 

 line about straight, the laterals a little larger and a little 

 further from the medians than the latter are from each other j 

 ocular quadrangle narrowed in front, a little longer than wide. 

 Clypeus a little less than the diameter of anterior median eye. 



Mandibles robust, scantily hairy, armed with four posterior 

 and two anterior teeth. 



Legs 2, 1, 4,3; when extended, second surpassing first 

 by its tarsus and third by tarsus and three fourths of pro- 

 tarsus ; fourth exceeding third by nearly its tarsus ; femora 

 armed with 3, 2, 3 spines above (fourth with 3, 2, 1) ; 

 patella? unspined; tibia} with 2, 2 spines below (the apical 

 pair absent), 2 in front, 2 behind; protarsi armed like the 

 tibite, that of the fourth with 2 extra apical spines in front ; 

 protarsus of first and second scopulate to base, of third and 

 fourth less scopulate basally. 



Ahdomen about one fourth longer than wide. 



Vulva consisting of a pair of horny black plates meeting in 

 a suture and circumscribing in front a deep narrowly oval or 

 lanceolate pit. 



Measurements in millimetres. — Total length 18; length of 

 carapace 7, width 6 ; length of first leg 23, of second 25, 

 of third 18-5, of fourth 21. 



hoc. Zomba, 3000-9000 feet (II. II. Johnston). 



This species may be allied to S. abnormis, Blackwall, from 

 the Shire" (Ann. & Mag. Nat. Hist. (3) xviii. p. 457), and to 

 S. (Hetcropoda) africanus, Karsch (Mon. Ak. Wiss. Berlin, 

 1S78, p. 325, pi. ii. fig. 6), from Querimba, both of which 

 are based upon immature female examples. Karsch, however, 

 gives the length of the second leg in africanus as 26 and of 

 the fourth 18 millim. ; the difference between the two is 

 therefore very much greater than in S. croceiceps. Apart 

 from other characters, S. abnormis differs from the form here 

 described in having the carapace as wide as long.
