Diagnosis. Differs from the typical S. trinotatus of the N. Reninsula in having the ab- 
domen paler, white for its greater p^rt, the vent and under tail-coverts pure white, 
the thighs pure white or with a very faipt rosy shade On their upper part only 
(Hartert 1). In the tj^oical form 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 Accipiter 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 Erpthrospiza for this species and A. kiogaster 
and griseigularis ^ but later the two latter species were very properly removed 
by Gurney and H. trinotatus made the sole representative of the genus, the 
name of which he amended to Erythrospizias. Count Salvadori, almost simultane- 
ously, pointed out that Erythrospiza had been employed already by Bonaparte 
for a Loxiine genus; and he advanced the name Spilospiza^) in its stead (g 1). 
The original description of Erythrospiza as applying to 8. trinotatus is imperfect 
and misleading; an analysis of the original description of the two genera Ery- 
throspiza and Teraspiza ( = Accipiter) shows that the only tangible means men- 
tioned for distinguishing between the two forms consists in the statement that 
in Teraspiza the inner yanes of the first four primaries are emarginated, while 
in Erythrospiza the emarginations extend to the fifth; but even this does not 
hold good for E. trinotatus in which the emarginations are usually only slightly 
cut out on the second, third and fourth, and not at all on the fifth primary. 
>8. trinotatus in reality differs markedly from Teraspiza — taking T. rhodogaster 
for comparison — in the rounded point of the wing, there being little difference 
1) We prefer Spilospizias to Spilospizn, as Grurney did for other accipitrine genera with names ending- 
in spiza, because aniCa means any small chirping bird, whereas aniliias is a falcon or sparrow-hawk.
