348 Dr. F. Briiggemann om Artamus monachus. 
Upperside dark brown. Anterior wing with twelve minute 
transparent spots: three at the middle of the costal margin, 
two of which are in the cell; six in a central oblique band, 
two of which are lunular; and three near the apex; a minute 
white spot on the fringe at the apex, and a lunular spot of the 
same colour near the analangle. Posterior wing with the outer 
half grey, bordered above with white, crossed near the outer 
margin by a band of dark brown. 
Underside. Anterior wing as above, except that there are 
two minute white spots above the lunular spot near the anal 
angle. Posterior wing with a band of white spots at the 
middle, a series of smaller white spots below these, and a large 
black spot at the anal angle bordered above and below with 
white. 
Exp. 155 inch. 
Hab. Amazons (Bates), 
Conognathus Platon of Felder is the typical representative 
of this genus; but as Mr. Kirby informs me that Conognathus 
is preoccupied, I have adopted Artewrotia of Butler and Druce. 
Thracides Aristoteles of Westwood also belongs to this genus, 
and bears very little resemblance to the species which Hiibner 
puts into his genus Thracides. 

XXX VIII.—WNote on Artamus monachus. 
By Dr. F. BRbGGEMANN. 
In 1850 Prince Bonaparte established a new species of Arta- 
mus from Celebes (A. monachus), with the following dia- 
gnosis :—‘ Capite, alis caudaque nigris” (Consp. Avium, i. 
. 843). ; 
; In 1877 Dr. Sclater established a new species of Artamus 
from New Ireland (A. ¢nsignis), with the following dia- 
gnosis :— Diversus ab A. monacho capite alis et cauda nigris” 
(Proc. Zool. Soc. 1877, p. 101). | 
Going further into the question, it may be mentioned in 
advance that A. monachus was first distinguished and named 
by Temminck; but as the Dutch ornithologist never gave a 
description of it, we have not at all to deal with an A. mona- 
chus of Temminck, as quoted by most authors. The next 
account of the species was given by the illustrious traveller 
Wallace, who described specimens from North Celebes and 
the Sula Islands (P. Z. S. 1862, p. 340), as having the head, 
wings, and tail ashy grey instead of black. Upon this, Lord 
Walden, in his elaborate memoir on the birds of Celebes 
(Trans. Zool. Soe. viii. p. 67), where also a good figure of the
