Diagnosis. Differs from the typical S. trinotatus of the N. Peninsula in having the ab- 
domen paler, white for its greater part, the vent and under tail-coverts pure white, 
the tliighs pure wliite or with a very faint rosy shade on their upper part only 
(Hartert 1). In the typical fonn these parts are whitish, washed with pink buff.

The differences between this form and the northern birds are slight and appa- 
rently not always pronounced. 
This little Celebesian Hawk, which Mr. Wallace speaks of as one of the 
most beautiful Hawks of the East, much resembles Aceipiter minullus of South 
Africa in the unusual markings of the tail, but differs from it and other species 
in so far that it must be placed in a genus or, better, subgenus for itself. 
In 1867 Kaup made the genus Erythrospiza for this species and A. hiogaster 
and griseigularis, but later the two latter species were very properly removed 
by Gurney and E. trinotatus made the sole representative of the genus, the 
name of which he amended to Erpthrospizias. Count Salvadori, almost simultane- 
ously, pointed out that Erythrospiza had been employed already by Bonaparte 
for a I.oxiine genus; and he advanced the name Spilospiza^) in its .stead (g 1). 
The original description of Erythrospiza as applying to S. trinotatus is imperfect 
and misleading; an analysis of the original description of the two genera Ery- 
throspiza and Teraspiza ( = Aceipiter) shows that the only tangible means men- 
tioned for distinguishing betweeir the two forms consists in the statement that 
in Teraspiza the inner vanes of the first four primaries are emarginated, whrle 
in Erythrospiza the emarginations extend to the fifth; but everr this does not 
hold good for E. trinotatvs in which the emarginations are usually only shghtly 
cut out on the second, third and fourth, and not at all on the fifth prrrnary. 
6'. trinotatus in realitv differs markedly from Teraspiza - takrng 1. rhodogaster 
for comparison - in the rounded point of the wing, there being little difference 
.) AYe prefer Spilospizias to Spilospizn, as Gurney did for other aocipitrine genera with names ending 
in spiza, bLanse Li^a means any small chirping bird, ^yhoreas is a falcon or sparrow-hawk.
