outer primaries; middle of crown, the back, jugulum, and lower part 
of thighs, with metallic violet or bronzy violet sheen; throat and chin 
with a dull greenish blue sheen; sides of crown, sides of occiput, all of 
lower back, rump, upper tail-coverts, breast, abdomen, and crissum, 
with metallic bottle green sheen; margins of all the superior wing- 
coverts, except the greater series, with glossy bluish, greenish or 
violet sheen; wing-quills and rectrices with slight bluish or greenish 
reflections, excepting the inner webs of the former, which are brown- 
ish, decidedly paler along the basal portion of the inner margin. 
This new race is most nearly allied to Gracula javana javana, with 
which it agrees in size of lappets and in having the supra-auricular 
bare space completely divided by a line of feathers. So far as known 
it is confined to the Anamba Islands. Birds of this species from 
Borneo and Sumatra seem to agree with those from Java. 
Doctor Abbott obtained seven specimens, four of which (Nos. 
171039, 174721, 170995, and 170905, U.S.N.M.) show slight evi- 
dences of molt. He found the species common on Pulo Piling, 
August 17, 1899; and about Telok Ayer Bini on Pulo Siantan, Sep- 
tember 5-6, 1899. The measurements of all the specimens collected 
are as follows:

The present species was first described in 1757 as Corvus javanensis 
by Osbeck,? in a pre-Linnaean book, which in 1771 was translated 
into English. This name has been in common use, dated from 1771, 
but according to present rules of nomenclature it is untenable, 
since the book in which it appeared was a mere translation of an
