1863.] MR. A. R. WALLACE ON THE BIRDS OF BOURU. 25 



therefore, I think, but little doubt that T. sabrina is but an indivi- 

 dual or local variety of the true Alcedo dea. 



Alcedo moluccensis. 



Alcedo moluccensis, Blyth, Journ. As. Soc. Bengal, 1847. 



Hub. Bouru, Celebes, and Gilolo. 



Ceyx cajeli. (PI. V.) 



Nigra, subtus rufo-lutea ; capita et tectricibus alarum punctis 

 parvis cceruleis ornatis ; dorse et caudce tectricibus pallide 

 cceruleis ; gula late alba ; genis nigris aut tenuiter cceruleo 

 striatis ; flexura et margine alarum, colli et frontis maculis 

 lateralibus rufis ; rostro pedibusque dilute corallinis. 



Above black ; beneath rufous yellow ; each feather on the head 

 marked with a very small, subtriangular, light-blue spot ; on the back 

 and upper tail-coverts the outer half of each feather is whitish blue ; 

 chin and throat pure white ; a frontal spot over each nostril, a patch 

 behind the ears, and the bend and margin of the wing rufous ; ear- 

 coverts black, and the space below them either black or very finely 

 striated with blue ; bill and feet pale coral-red ; iris dark. 



Length 6 inches ; wing 2f inches ; bill, from front, If inch. 



Hab. Bouru. 



Remarks. — This species is very like C. lepida ; but differs in the 

 very small spots on the head and the stripe on the back being of 

 quite a different blue colour, and also in the scapulars being entirely 

 black, whereas in the other species they are tipped with rich blue. 

 I have named this species after the town or fort of CajeU in Bouru, 

 to which island this pretty bird is most probably strictly confined.

Remarks. — My specimen agrees exactly with Gould's figure and 

 description. I did not meet with the species in any other of the 

 islands.
