1900.] INSISTS AND ARACHNIDS FROM SOMALIL AND. 59 



This form is evidently aliied to the typical P. 'pallidas ; but 

 until adults of the latter come to hand for comparison, it is im- 

 possible to say what the exact relationship between the two may 

 be. The original examples of P. phillipsi are a pair of females 

 obtained at Dooloob. Mr. Lprt Phillips subsequently procured an 

 adult male and a young female on the Goods Range of mountains. 

 The former has L7— 18 pectinal teeth, a longer tail and larger vesicle 

 than the female, and lobate movable finger on the chela. The 

 young one is as large as a co-type of P. pallidas, the carapace in the 

 two measuring 11 mm. Moreover the posterior tarsal lobe is tipped 

 above with bristles a^ in P.pallidus, not with a spine as in the adult 

 P. phUMpsi. But the shape of the hand in the young P. phillipsi 

 is different, this organ being very noticeably narrower, and the 

 tubercles on its upperside are much sharper and more strongly 

 de lined. 



The following actual measurements (in millim.) of the two 

 examples may be advantageously compared : —

As wdl be seen, there is practical identity of measurements ' 

 except where the width of the hand is concerned.

and kindly smt to the British Museum three additional examples, 



an adult male ami female and a yoUOg Specimen Considerably smaller 



than the type. The characters upon which the species was based 

 prove perfectly constant. The adull male and female are much
