Hab. Islands of Batchian and Halmahera. 
Ad. splendide ultramarinus, corpore suprh, saturatiore et capita nigro-ultramarino; gul4 vix pallidiore et cyaneo 
striata : remigibus primariis in pogonio interno nigyo marginatis et plaga pallide ceerulea ad basin notatis : rostro 
et pedibus rubris : iride fusc^. 
Adult male (Batchian).—Rich deep cobalt or ultramarine-blue, upper parts darker, and the head 
blackish blue ; throat rather paler and striped with very pale blue; quills rich ultramarine-blue, the 
primaries slightly margined with black on the inner webs ; a light blue patch on the basal part of the 
primaries: bill and legs pale vermilion-red, with a slight orange tinge; iris brown. Total length 
about 11'5 inches, gape 1’65, wing 7*9, tail 4’5, tarsus 0’72. 
The present species, one of the richest coloured of the Rollers, is only known as an inhabitant of 
the Moluccas, where it has been obtained on the islands of Halmahera and Batchian. First discovered 
by Mr. A. R. Wallace on Batchian, it has since but seldom been obtained, and is consequently still 
a very rare bird in collections. Schlegel states (1. c.) that in the Leyden Museum there are specimens 
obtained by Bernstein in Batchian and at Bessa on the north-east coast of Halmahera, and 
Dr. Guillemard, who obtained one near the village of Batchian in the month of December, remarks 
that it was regarded by the natives as very rare. 
So little is known respecting this bird that there is absolutely nothing on record regarding its 
habits or nidification, but it probably does not differ in these from the rest of the Eurystomi. 
The specimen figured is in my own collection.
