$ . Colour uniformly black or blackish green, with hands and 

 vesicle tinged with red. Carapace covered with coarse granules or 

 tubercles, smoother above as a rule ; a little longer than ] st and 

 2nd caudal segments, shorter than 3rd and 4th. Terga also coarsely 

 granular or tubercular, with a larger central tubercle. Sterna 

 smooth, the last obsoletely crested. Tail more than three and a half 

 times as long as carapace, superior and lateral intercarinal spaces 

 coarsely granular, superior and in a less degree supero-lateral keels 

 denticulate ; inferior keels of 3rd segment scarcely denticulate ; keels 

 of 5th strongly dentate; vesicle coarsely granular at the sides as well 

 as below. Chelce with huinerus dentate above and in front : brachium 

 almost smooth, a few granules in front ; upper surface of hand very 

 smooth, finely reticulated, punctured, its inner edge denticulate, 

 nearly straight ; immovable finger scarcely keeled ; width of hand 

 exceeding length of underhand. Tarsal spines 4-5. Pectines small, 

 teeth 10-12. 



c? like female, but more closely granular and with chelae longer 

 (see measurements). Pectines quite small, not larger, and with 

 teeth not more numerous than in female. 



Measurements in mm. $ . Total length 130, carapace 19, tail 

 70, brachium 15, underhand 13, movable finger 20-5, width of 

 hand 16. 



c? . Total length 113, carapace 17, tail 63, brachium 15, under- 

 hand 12-5, movable finger 18, width of hand 13. 



Loc. S.W. India : the Malabar coast from Trevandrum (Ferguson) 

 northwards to Yelgit and Jedkal in Mangalore and the Mangalore 

 Ghats (Battie); also Dharwar ( Woodrow), and Coorg above the 

 Ghats.* 



Subspecies kanarensis, nov. 



Of the same size, colour, and sculpturing of hand as the typical 

 form, but much smoother : the median area of the carapace smooth 

 or weakly granular ; terga also furnished in the middle with only 

 a few granules or almost smooth, sometimes only the three trans- 

 versely set tubercles present ; intercarinal spaces of tail also more 

 sparselv granular and the keel less strongly denticulate. 



Loc. "Kanara (Bell). 



* In his original description of this species, which he erroneously identified 

 with the Scorpio afer of Linn., Simon says " appears to be common in Bengal." 

 This, however, is almost certainly an error, since the only species of the genus 

 Palnmrueus known to occur in Bengal are swammerdami and hengalensis, and 

 possibly the Burmese form oatesii.
