 tarsus, L6.5 17 (average, L6.8)! Three females: Wing, L45 L5] 

 (average, L47.8) ; tail, ( .»l LOO (average, 96.8); exposed culmen, 7-2-

This excellent form differs Prom Ramphalcyon c. gurial about as 

 from R. c. burmanica, and additionally in lacking the whitish chin 

 and tin-oat, these parts being ochraceous buff, and not so much paler 

 than the remaining lower surface. It is of the. same size as Ram- 

 phalcyon capensis capensis, but is readily separable by its distinctly 

 brown-capped pileum, with but very little ochraceous tinge, duller, 

 much more greenish hack, wings, and tail, and more deeply colored. 

 more uniform lower surf ace. So far as known, Ramphalcyon capensis 

 simalurensis is confined to the island of Simalur. for the neighboring 

 islands and the mainland of Sumatra are inhabited by different forms, 

 as hereinafter described. It seems to be, however, certainly only a 

 subspecies, connected by individual variations with the mainland race 

 through the birds from Nias and the Batu Islands. The females of 

 Ramphalcyon capensis simalurensis differ considerably from the 

 males in larger size, duller \\ ings and tail, and decidedly duller, more 

 brownish back.
