HADOGENES GUNNINGI, n. sp. 



? . Carapace very shallowly and widely emarginate in front. 

 Last abdominal tergite very short, more or less rounded behind 

 and almost semicircular in outline, much broader than long. Tail 

 3f times as long as the carapace, which is as long as the first and three- 

 fourths of the second segment ; first segment higher behind than broad, 

 the upper crests smooth ; terminal tooth of superior crests enlarged 

 but not spiniform in segment 2, less enlarged in segment 3 ; vesicular 

 segment distinctly compressed, not turgid, only slightly wider than 

 the hind end of the fifth segment, its upper side slightly convex. 

 Upper surface of humerus of palp with no strong ridge just behind 

 the anterior border ; length of humerus along upper hind margin 

 2-J-- 2-f times the width of the upper surface. Pectines with 13-16 

 teeth. Colour dark brown mingled with olive-green, vesicle paler 

 brown. 



Loc. An ad. ? :;: from Pretoria (type, No. 4,041) collected by Dr. 

 J. W. B. Gunning, Director of the Staats Museum at Pretoria, in 

 which are several other specimens. I am much indebted to Dr. 

 Gunning for the type and for the loan of his other specimens. 



Measurements. Total length 106 ; length of carapace 13J ; length 

 of last abdominal tergite 8i, width 12 ; length of tail 50 ; length of 

 I. segment 6|, width behind 2f, height behind 3^; length of II. seg- 

 ment 8^, width of vesicle 2f , height 3 ; length of humerus 12f , 

 width of upper surface 4i, length of anterior surface (measured along 

 middle from the large tooth near base) 8|, width 3i ; length of hand 

 25, width 8, length of hand-back 14. 



Very near troglodytes (Pet.) from Ehodesia but smaller, with 

 relatively broader humerus and narrower vesicle. 



* The adults in the genus Hadogenes are readily distinguishable by the 

 presence of a large lobe at the base of the fingers of the palps. In immature 

 specimens this lobe is obsolete.
