Palpal organ resembling closely that of P. murtnus, the

Palpal organ of Pteruwchilus Hindei. 



Measurements in mm. Length of cephalothorax 13*5, of 

 patella, tibia, and tarsus of palp 14*75, of iirst leg 49, of second 

 [^^ 44"5, of third leg 41, of fourth leg 50, of patella and tibia 

 of first leg IQ'b, of patella and tibia of fourth leg 15'25 ; total 

 length 27. 



Jrlab. A single male specimen was collected by Mr. S. L. 

 Hinde at Fort Hall (4400 feet), British East Africa. 



Remarks. The male of P. Hindei differs from that of 

 P. murinus, to which it is closely allied, in the much smaller 

 size and in that the ceplialothorax equals the patella, tibia, 

 and tarsus of the maxillipalp, whilst in murinus the cephalo- 

 thorax considerably exceeds the patella, tibia, and tarsus of 

 the palp in length.

(J . — Cephalotliora.x longer than patella, tibia, and tarsus of 

 maxillipalp, and shorter than patella and tibia of fourth leg. 



Legs. Metatarsus of first leg sinuate and dilated distal ly, 

 tibia of first leg more slender than femur. Patella and tibia 

 of first leg exceeding patella and tibia of fourth in length. 



Size. This species is much larger than P. Ilindei.
