ANATOMY OF ARACHNIDS 3 



ir. PEDIPALPS 



Pocock has divided the Pedipalps into two distinct orders, 

 the Uropygi and the Amblypygi. The former group consists 

 of the Thelyphonides and Tartarides, and the latter of the 

 PhrjTiides. This separation seems to be justified on exam- 

 ination of the coxal glands, which differ very widely in these 

 two groups. 



Amblypygi 



The description of the coxal glands of the Phrynides given in 

 the pre\ious article was based upon two species of Tarantula 

 from Central and South America. Since then I have had an 

 opportunity of examining several species of Phrynicus and of 

 the Charontini family from India and the Malay Peninsula. 



Phrynini PhrjTiicus ceylonicus, Ceylon. 



Phrynicus nigromanus (Gravely), India. - 

 Charontini Charon grayi (Simon), Manila.^ 



Stygophi-jTius, caves in Malay Peninsula. 



Sarax, caves in Malay Peninsula. 



Phrynicho-Sarax singapurae (Gravely), Lang- 

 kawi Island, Kedah. 



Charinides bengalensis (Gravely), Bengal. - 



The coxal glands of Phrynicus are precisely similar to those 

 of Tarantula as previously described; i.e., there is a saccule on 

 segment III from which a very extensive coiled labyrinth tube 

 leads backwards to segment VI, where the tube loops forward 

 and runs anteriorly as a long straight tubule to the outlet on 

 segment III, just below the saccule and posterior to appendage 

 III (diagram 1, fig, 1), The labyrinth is peculiar in that the 

 central portion is lined with a basophil epithelium which ap- 

 pears to be secretory, and it was suggested that the secretion 

 might be used for salivary purposes as there is no distinct sali-

 alcohol for twenty years, but were in fairly good condition.
