These birds are nearly allied to St. panayensis Sharpe 
from the island of Panay, Philippines. I had no material 
of this species at hand for comparison, but Dr. Hartert, 
to whom [ sent the birds, very kindly compared them with 
his material of panayensis and informed me, that the birds 
from Ceram differ from panayensis by the smaller bill, 
lighter bluish upper surface and breast, more whitish under 
tailcoverts and much shorter wings. I have the honour to 
name this form after my esteemed colleague for his kind 
assistance.

sooty black; scanty feathers of the tarso-metatarsus blackish
