408 DR. O. FINSCH ON BIRDS FROM [May 1, 



number altogether 10 species. One of these, a Kingfisher, although 

 known already to Forster, proves to belong to an unnamed species. 

 A closer exploration of the group will probably bring to light fur- 

 ther species, peculiar to the different islands, such as, under similar 

 circumstance:^, the excellent researches of Mr. Layard have recently 

 made known to us in the Feejee group. 



1. COLLOCALIA CINEREA (Gm.). 



Herse Forsteri, Ilartl. 



C. vanicorensis, part., Finsch & Hartl. Orn. Central-Polyn. p. 47. 



One specimen, agreeing generally with the description communi- 

 cated to me by Dr. von Pelzeln from a Tahitian specimen in the 

 Vienna Museum {vide Journ. d. Museum Godeffroy, Heft xii. 1876, 

 p. 25) ; but the coloration is as dark as in O. vanicorensis; the rump 

 is not pale, as in C. spodiopyfjia, but uniform with the remaining 

 upper parts ; the single featliers show very narrow light lateral 

 margins ; but these are hidden. 



The specimen seems, therefore, to be identical with the Tahitian 

 species first mentioned from this locality by Forster, and agrees 

 exactly in its larger size, by which it may be distinguished from the 

 other species inhabiting the Pacific. 



2. Halcyon godeffroyi, sp. uov. 



Alcedo collaris, var. ii., Forst. Descr. Anim. 1844, p. 163. 



Todirhamj}hus, sp., Hartl. Journ. f. Orn. 1834, p. 170. 



Adult. Head, neck, mantle, and whole under surface, including 

 the under wing-coverts, white ; shoulders, lower back, quills, and 

 tail cobalt-blue ; inner webs of wings smoky black, margined with 

 white ; from the lores through the eye and temporal region a narrow 

 black band encircling the najie ; basal half of bill black, lower 

 mandible pale horn-colour ; feet black. 



There are three specimens which agree perfectly with the descrip- 

 tion above given. The white middle portion of the mantle is faintly 

 stained with rusty. 



Young. Frontal margin, extending as a narrow superciliura to 

 above the eye white; remainder of head obscure marine-blue (on 

 the crown appear three new f)ure white feathers) ; lores and a broad 

 band around the nape dull black, the same as the hind neck and 

 upper portion of the mantle ; on the hinder mantle some white 

 feathers, washed with pale rusty ; under surface white, with dark 

 edgings to the feathers of the sides of the crop ; smaller upper wing- 

 coverts with narrow whitish tips.

The Kingfisher of the Marquesas has not come under examina- 

 tion since the time of Forster, who described the bird correctly as a
