punctured ; not geniculate beneath the aculeus. Chele with humerus granu- 
lar and granularly crested above, brachium smooth, with smooth crests ; 
hand smooth, scarcely crested ; digits short, the movable being twice the 
length of the hand-back, shorter than the carapace, furnished with eight rows 
of teeth. Movable and immovable digits of mandibles furnished with two 
inferior teeth. Cox of legs granular ; external surface of legs granular and 
carinate. Pectinal teeth, 17. 
Total length, 22 mm. 
Locality.—Sokotra (Mt. Raggit, 1000 feet) —a single specimen. 
Recognisable at once from the Arabian and Persian B. melanurus by the 
smoothness of the upper caudal crests, etc. 
Chilopoda (Centipedes). 
(5) Asanada socotrana. 
Closely related to Asanada brevicornis from North India and Burma, but 
recognisable by having the anal sternite transversely oblong instead of semi- 
circularly rounded, the antennz longer and much more attenuate, the apical 
segment being much longer than wide, instead of sub-spherical as in 
A. brevicornis. 
Length, including anal legs, up to about 50 mm. 
Locality. —Sokotra (Hadibu Plain ; Dahamis, 350-1000 feet; Jena- 
agahan, 1200-2500 feet ; Homhil, 1500-2500 feet). 
Diplopoda (Millipedes). 
(6) Odontopeltis grantii. 
Colour of mature specimens nearly blood-red with a blackish median 
dorsal line ; sterna, tips of keels, legs, and antenne yellow. Dorsal surface 
smooth, polished, or sparsely granular posteriorly and laterally, not trans- 
versely sulcate ; the anterior suture not beaded ; keels of medium size, with 
convex anterior shoulder, obtusely rounded or obtusely angled anterior angle, 
acutely produced, subspiniform posterior angle ; the anterior border of at

except the anterior three and the posterior two much more strongly dentate 
or tuberculate. 
Length (2) up to 30 mm. ; (d) 27 mm. 
Locality.—Sokotra (Mt. Raggit, 1000 feet ; Dahamis, 380-1000 feet ; 
Jena-agahan, 1200-2500 feet ; Homhil, 1500-2500 feet). 
(7) Odontopeltis forbesii. 
Larger and darker in colour than O. granti, dorsal surface a rich reddish 
brown tint, clouded with black and with narrow median black stripe ; sterna 
reddish. 
Further differing from 0. grantii in the structure of its organs of copula-
