 series 38. 



JJuh. Jebel Fazogli, Blue Nile. Alt. 3500 feet. 



Type. Old male (Stage VIII.). Colkcted bj Mr. A. L. 

 Butier on the 4th May, 1911. 



The British Museum possesses a second specimen from 

 Gebel Ain on the Wiiite Nile. Tlie only other, geogra- 

 ])hically neighbouring, species with a black dorsal mark is 

 scioaiia, but that species is at once distinguishable from 

 hutleri by its greater size, long soft far, conspicuous dorsal 

 mark, and buff belly.

Genus Neobuthus, nov. 



Carapace without distinct keels (with the exception of the 

 ill-defined pair leading forwards from the ocular tubercle). 

 Posterior grooves of carapace very similar to tliose of the 

 genus But/ieolus, Sim. Genital operculum with its two 

 valves similar in shape to and almost as large as those of 

 Nanohuihus, Poc. Posterior tergites with three keels, the 

 lateral ones being weak. Immovable finger of chelicera with 

 u single tooth on the lower edge. Chela stout, especially the 

 brachium ; the rows of granules of the movable finger are 

 weak, and the basal row comes to an end at a short distance 

 from the point of articulation of the finger. 



J^eohuthus berberensls, sp. n. 



Carapace finely granular throughout, the granulation being 

 slightly coarser at the posterior margin on each side of the 

 groove. A pair of weak and indistinct keels runs forward 

 from the ocular tubercle. Median eyes widely sei»arate as in 

 JSanohuthus andersoni, Poc. Grooves of the middle of the 

 posterior margin deeper than in iV. ondersoni. 



Tergites with the granulation fairly strong at the sides, but 

 rather fine in the middle, and very fine (almost invisible)
