£ . Colour entirely yellow throughout/with exception of the eyes 

 which are black. Carapace granular throughout except for the 

 ocular tubercle and a ridge on each side of the median frontal 

 depression, which are smooth : groove surrounding ocular tubercle 

 behind not so deep as in B. melanurus. Terga granular throughout, 

 with a single median keel, the last not smooth on the inner side of 

 the median keels as in B. melanurus. Sterna and coxa' smoother 

 than in B. melanurus, the former finely granular both externally 

 and on the inner side of the pulmonary area ; the last granular 

 throughout, the granular crests much less distinct than in 

 B. melanurus. Tail of much the same form as in B. melanurus ; 

 segments 1-3 carinate as in that species, 4th segment covered with 

 granules below and at the sides, not so conspicuously pitted as in 

 B. melanurus; the inferior lateral crests developed, and the inferior 

 medians also traceable ; 5th segment covered with granules below, 

 with a median granular keel ; lateral keel more irregularly dentate 

 posteriorlv than in B. melanurus, and more noticeably concave before 

 the anal lobe ; vesicle larger, aculeus thinner, and pits on vesicle 

 and 5th caudal segment fewer than in B. melanurus. Chela? with 

 upper surface of brachium more granular, and movable finger 

 shorter than in B. melanurus, the latter being distinctly shorter than 

 the carapace, furnished with 8 rows of teeth, the basal of which 

 is shorter than in B. melanurus ; the enlarged teeth represented by- 

 transverse rows of three each, the inner of these not in advance 

 of the enlarged posterior tooth of the median rows ; external to 

 the latter and behind it there is a second tooth, so that the external 

 series consists of two teeth, and not of one as in B. melanurus. 



cS . Differs from $ in having the median keels and adjacent 

 parts of the last abdominal sternum and of the 1st caudal segment 

 smooth, and the lower side of the 4th and 5th segments less 

 granular and scarcely mesially carinate. Pectinal teeth 16-17 

 in $ , 21-29 in 6 . 



Length up to 35 mm. 



Loc. Sincl ; Kashmor Bund and the Kelat Frontier (Kemball).

 1897 ; Kracp. Tier)'., Scorp. etc. p. 36, 1899. 



j. Colour as in B. pallidus, but the terga slightly infuscate. 

 Very closely allied to that species in all structural characters, but 

 with the tail less coarsely granular : for example the sides of the 

 2nd segment just external to the super o-lateral keel are furnished 

 with only a few small granules and a few pits, the corresponding 

 area of the 3rd and 4th is smooth and distinctly pitted, and the 

 lower side of the 4th is furnished with a very few granules. In 

 c? of />'. pallidus, on the contrary, the upper portion of the lateral 

 surface of (lie 2nd segment is covered with tubercles, of the 3rd 

 it is granular and rugose, and of the 4th distinctly though not
