84 REPORT ON ZOOLOGY, MDCCCXLIII. 



for Wagler's generic name, Malacorhynchus, that of Hyme- 

 nolcdmus. (Ann. Nat. Hist, xi, p. 369.) 



From Forster's Anas mulacorhynclius, from New Zealand, Wagler (Isis, 

 1832, p. 1235) had formed the geiras Malacorliynclms, and had also added to it 

 the soft-billed Duck of New Holland, which, a short tune previously, 

 Swaiusou had also raised into a distinct genus, and indeed under the same 

 name, of Malacorliynchus. Gray now shows that the two species do not 

 belong to the same genus, since in the New Holland one, the hinder toe is 

 without lobes, which, on the contrary, is lobed in the New Zealand species. 

 The name, J/#fe%w//Ks, Swains., being retained for the former, the latter 

 must receive a new one, for which he has selected that of Hymenolaimiis. 



New Peruvian species by Tschudi are, Anas leucogenys, and Anser mon- 

 tana. (Archiv, p. 390.) 



Nilsson (Isis, p. 218) has furnished some remarks upon a tame Duck 

 which had assumed the colour and appearance of the Mallard. 



It is to be recorded as a remarkable fact, that both Count v. d. Miihle and 

 Lindermayer mention the Cygnus musicus as a stationary bird in Greece, where 

 it breeds in the lakes and marshes ; according to the former, in considerable 

 numbers. 



STEGANOPODES. On the habitat and mode of breeding 

 of the PeHcanus crispus, Count v. d. Miihle has communi- 

 cated some interesting notices in his Beitrag. z. Ornithol. 

 Griechenl. p. 132. 



It is very plentiful in Greece throughout the year, and in many lakes and 

 marshes there are extensive breeding colonies of it. P. onocrotalm, on the 

 contrary, is extremely rare in Greece ; Count v. d. Miihle, indeed, hardly be- 

 lieves that it breeds there, but that in the winter only a few scattered indivi- 

 duals reach that country. Lindermayer mentions only P. onocrotalus, and says 

 that it is always found among other entire families on the Licari Lake. This 

 statement, however, arises from confounding the species with P. crisjms, 

 since, as Count v. d. Miihle remarks, the latter is the only one which inhabits 

 the above-mentioned lake. 



Pelecanus rufescens was met with in large flocks by the Niger Expedition, 

 near Egga, in the month of October. Fraser (Ann. Nat. Hist, xii, p. 133). 



Dysporus varieyatm was discovered by Tschudi, as a new species, on the 

 coasts and islands of the Pacific. (Archiv, p. 390.) Phalacrocorax kypo- 

 leucos, Brand, leucogaster, Gould, and melanoleiicos, Veill., have been figured 

 by Gould in the c Birds of Australia' (parts 11, 12). 



PYGOPOUES. (Ib. part 12) are figures of Podiceps gularis, Goiild, and 

 poliocephahts, Jard.
