Loc. British Guiana [W. L. Sclater). 



[Kraepclin (MT. Mus. Hamb. xi. p. 178, 1894, and Das Tierr., Scorp. etc. p. 173, 1899) states that 

 B. Sclateri is identical with B. Schaumii of Karsch, and possibly with quinquedentatus of this latter author, 

 both of which were recorded, though no doubt erroneously, from India. But the presence of only 

 five pectinal teeth in tlie hatter forbids, to my mind, such an opinion. B. Schaumii, judging from 

 Kraepelin's description, is closely allied to B. Sclateri, but the fact that the third caudal segment is higher 

 than wide la Schaumii, and wider than high in the two known examples of Sclateri, makes the synonymy 

 doubtful.]

The following -well-marked new species were discovered by Messrs. McConnell and 

 Quelch : — 



Bkoteochactas grakosus, sp. n. 



Colour. Carapace, terga, and tail almost black ; legs, palpi, and vesicle of tail deep 

 reddisli brown, the legs with paler line and spots ; fingers black. Carapace and ferga 

 entirely covered with line close-set granulation ; ocular tubercle coarsely punctured ; 

 carapace a little longer than the first and second caudal segments, a little shorter than the 

 fifth. Coxce and sterna finely punctured, the last sternite weakly and closely granuhu" 

 laterally. Tail more than four times the length of the carapace, narrowed jjosteriorly, 

 the segments nearly parallel-sided : the first wider than long ; second slightly longer than 

 wide ; fourth not twice as long as wdde ; fifth a little more than twice as long as -wide ; 

 intercarinal spaces finely granular ; inferior and infero-lateral keels obsolete on segments 

 1 and 2, scarcely traceable on segment 3, represented on segment -l by iri-egularly 

 arranged larger granules ; stxperior and supero-lateral keels weak, weakly granular ; 

 inferior surface of fifth coarsely granular between the keels; vesicle granular, narrower 

 than third segment, -wider than high. 



Chelce finely granular; upperside of humerus and Ijrachium with coarser granules 

 between the keels ; upperside of hand covered -with a reticulation of fine granules; inner 

 surface similarly granular ; back of hand coriaceous ; fingers granular at base. Width of 

 liand equal to length of external keel of hand-back, less than length of movable digit ; 

 digits longish, movable as long as the carapace, immovable about twice as long as its 

 basal width. Femora and tibiae of ^^^* granular, the granules intermixed with punctures 

 on the tibia, following segments closely punctured ; tarsi short, not twice as long as 

 high, convex above, incrassate distally, armed with long sette arranged more or l(!ss 

 regularly in two rows. 



Measurements in millimetres. — Total length 46 ; length of carapace 6"5, of tail 29'.j ; 

 width of 1st segment 3-5, of 5th 2'8 ; width of hand ou ; length of hand-back .5, 

 of movable finger 8-5. 



Loc. Base of Mt. Roraima (3500 feet alt.).
