abdomen the white bars are broader and the brown ones narrower, and the barring 
on the lower breast is better defined than in the other sex; under tail- coverts white 
'in one specimen slightly barred towards the tip). The females of Sula have the 
under tail- coverts barred and in regard to the barring of the under surface would 
appear to resemble the males of Celebes, but there are only one or two males 
with the sex satisfactorily ascertained in the Leyden Museum for comparison. 
The female of Celebes is more spotted below.

9 As will be found more fully explained under the heading : Haliastur indus, a long connecting hyphen 
[e. g. S. rufipectus — sulaensis) is used in this work to indicate the connecting forms between subspecies; or, 
where it may be safely said that such individuals have stronger leanings to one subspecies than to the other, 
the sign >> or <[, respectively [S. rufipectus >> sulaensis) indicating that the affinities are more with the typical 
form, or (-S', rufipectus ■< sulaensis) with the latter form.
