classify the forms according to their natural affinities. It is rarely that monographers 

 and artists take such laudable pains to supply the wants of students. In the monograph

 single species, except the " British G. Turtoni " and its " Philippine analogue, G. macro- 

 $cki.<tma i Desh." This is the more remarkable, as most of the species were described by 

 Desh., with localities, in P. Z. S. 1855, pp. 167-181.
