116 MESSRS. HARTLAUB AND FINSCH ON THE [Feb. 13, 



with great pleasure I have this evening to offer a most striking 

 proof of the correctness of these views, one of the Kagus at the 

 Gardens having had the kindness to lay a very fine egg, which I now 

 place before you. (See Plate XII. fig. 3.) This egg was rendered 

 useless for hatching immediately after it was laid, by being pecked by 

 the bird that laid it, or by some other bird in the aviary. It is, how- 

 ever, a very fine and well-marked specimen, and in many particulars 

 closely resembles the egg oi Eurypyga (PI. XII. fig. 4), but perhaps 

 exhibits rather more of the form of tbe eggs of the Cranes (Grus) 

 than of the Rails and Plovers. Moreover the lively movements of the 

 bird as described by me in 1862 fully support its affinities with the 

 Cranes, and show, I think, that it has less affinity to the Ardeine 



group.

4. Additional Notes on the Ornithology of the Pelew Islands. 

 By Dr. G. Hartlaub and O. Finsch*. 



A new collection from the Pelew Islands has been submitted to our 

 examination. This collection was formed by the late Dr. Semper of 

 Altona, and is now deposited in the Museum of that town. It con- 

 sists of eighteen species, two of which are undescribed : — 



1. CoLLOCALIA VANICORENSIS, Q. & G. 



The only difference between this oceanic species and O. francica 

 from the Mascarene Islands consists in tbe colour of the under tail- 

 coverts, which are of a simple brown colour in C. vanicorensis, 

 of a much darker and bronze-glossed hue in C. francica. 



2. Halcyon sanctxjs, Vig. & H. 



Two younger birds, not different from Australian specimens. 



3. Myzomela rubratra. Less. 



4. PsAMATHiA ANN^, Hartl. P. Z. S. 1868, p. .5, t. ii. 



Av. jun. Supra magis brunnescens, subtus magis in fulvum ver- 

 gens ; subalaribus albo Jlavoque mixtis ; Jlexura alee Jiava. 



5. Artamus leucorhynchus, Gm. 



Lanius manillensis, Briss. ii. p. 180, t. 18. f. 2. (descr. opt.) ; Buff.
