In a more recent communication Dr. Shircore states : — " I think it must be 

 different from G. jia.lpalis. I have seen so many specimens of G. palpalis and

of very rocky streams, whereas the large one occurs along streams of quite c

Genital armature of the male (fig. 13). Superior claspers {sc) united by a 

 membrane ; base of clasper four times broader at the base than at the distal 

 extremity, with the inner basal portion extended inwardly so that it comes very 

 near to the juxta ; outer basal portion broadly rounded and with a broad curved 

 and somewhat attenuated process, the tip of which rests upon the inner basal 

 process ; this portion of the clasper is clothed with fine pubescent hairs ; margins 

 gradually tapering distally ; apex suddenly truncate, the inner half bearing a 

 few short spines ; bristles on the inner lateral margin gradvially shortening 

 distally, those on the outer lateral margin few in number, some of which are
