352 Mr. R. B. Sharpe on the Genus Todus. 



one above described in the colouring of the undersurface, 

 which is white^ tinged with yellow on the middle of the ab- 

 domen and under tail-coverts ; the throat is pale carmine-pink, 

 very thickly clouded with white margins to the feathers ; and 

 the pink on the flanks is not nearly so much developed as in 

 the male. I should not have doubted the sexual determina- 

 tion of the female, had it not been for a third specimen, also 

 procured from Mr. Cuming at the same time as the others. 

 This bird is pure white underneath, excepting the under wing- 

 and tail-coverts, which are yellow, and the pink flanks and 

 throat-spot. It has a very narrow and slender bill, and is the 

 Todus angustirostris of the ' Hand-list.^ Beyond this cha- 

 racter and the white undersurface, the bird agrees with T. 

 subulatus ; and my idea is that T. angustirostris is the female, 

 and that the intermediate Cumingian specimen is the young 

 male. The bird is a connecting link between the two ex- 

 tremes, being intermediate in size of bill and length of wing. 

 Should my suggestion prove correct, the following measure- 

 ments may be compared : — 



S. Domingo {Cuming). Tot, length. 



a. d ad. [?] 4-4 



b. $ ad. [?J 3-7 



c. 6 juv. [?] 4-1 



Sexual difference may account for the length of bill in the 

 Jamaican T. viridis referred to above ; the variation of bill is 

 illustrated in the plate, which represents the two specimens 

 in the Museum, one of which (fig. 2) I consider to answer to 

 T. angustirostris of Lafresnaye.
