1867.] DR. G. HARTLAUB ON BIRDS FROM THE PACIFIC. 829 



the fine greenish-blue colour of the back ; a second has the forehead 

 and superciliaries white ; in another the crown of the head is white, 

 with some bluish feathers in the middle, the auricular region and a 

 very narrow interrupted nuchal collar being of the same colour ; in 

 a somewhat younger specimen there is only one dark spot on the 

 white cap, and the colour of the back is an obsolete dirty green. 



For the complete synonymy of this species, conf. Cab. Mus. Hein. 

 ii. p. 159. "Tanatick" inc. 



The only existing original figure is that of Gould's {Halcyon sau- 

 rophaga), in the ' Zoology of the Sulphur.' It shows the head all 

 white. 



H. alhicilla has been collected on the Marian Islands, New Ire- 

 land, New Guinea, Batjan, Morotay, and the Pelew group. 



4. Myzomela rubratra. Less. 



Two ad. spec, Pelew group and Carolines. "Sisebanjo" inc. 



The Pelew group has been already indicated by G. R. pray as a 

 locality for this species. Von Kittlitz observed it on the island of 

 Ualan, and gives interesting details about its manners, propagation, 

 &c. We consider the Myzomela major of Bonaparte to be a merely 

 nominal species (conf. Von Kit-tl. Reise, i. p. 381). 



5. Collocalia vanicorensis (Q. & G.). 



It is extremely difficult and uncertain to find out definite differen- 

 tial characters between some of these CollocallcB. A fine specimen 

 of the true C.fuciphaga from the island of Reunion, in the Bremen 

 collection, resembles in almost every respect our CollocalicB from the 

 Viti and Pelew group ! 



Inc. "Cobusock." Von Kittlitz mentions this bird under the 

 name of Cypselus inquietus. He describes it as observed on the 

 island of Ualan (Reise, ii. p. 26). 



6. Monarcha godeffroyi, n. sp. (PI. XXXVIII.) 



Ad. Alba ; capite toto cum mento et gutture, alls et Cauda nigris ; 

 subalaribus et subcaiidalibus nigris ; rectricibus nonmtllis late- 

 ralibus macula alba minuta vix conspicua apicali notatis ; rostro 

 plumbeo, tomiis et apice pallidioribus ; pedihus nigricantibus. 



Long, circa 7|", rostr. a fr. 7'", alse 3" 2'", caudse 3", tars. 10'". 



Jun. (fcem.?). Dorso nigro alboque vario; collo toto albo; capite, 

 alis, Cauda, pectore et ahdomine nigris. 



Juv. Supra sordide cinerascens, fulvo lavata ; tergo uropygioque 

 magis fulvescentibus ; remigibus et tectricibus fulvo marginatis ; 

 gastrceo ochroleuco. 



Perhaps confined to the island of Yap, where the three specimens 

 here described were shot. This fine new bird is nearly allied to 

 Monarcha rugensis, from the much more eastern Hogoleu group. 

 But the distribution of the black and white colour is altogether dif- 

 ferent.
