undescribed forms. The most interesting of these new birds are 

 Kakatoe parvulus abbotti, which marks a new western limit for the 

 genus; Perissolalage chalepa, a new genus and species of Campephag- 

 idae, related to Lalage Boie; a drongo, Dicruropsis pectoralis solom- 

 bensis; and an apparently distinct species of white-eye, Zoster ops 

 solombensis, allied to Zosterops flava of Java. 



Only three species were obtained on Arends Island, November 23 

 to 24, 1908, but one of these, Megapodius dupemjii gouldii, is worthy 

 of particular note as extending the western limit of the known range 

 of this species. 



On the island of Mata Siri Dr. Abbott collected from November 7 

 to 12, 1907, and from November 25 to December 1, 1908, gathering on 

 these occasions altogether 13 specimens of birds of eight species, five 

 of these representing new subspecies. The most important of the new 

 birds are a bulbul, Pycnonotus brunneus zaphaeus, apparently most 

 closely allied to Pycnotiotus brunneus brunneus from the Malay Penin-- 

 sula; Malacocinda abbotti sirensis, allied to Malacocincla abbotti olivacea 

 from the Malay Peninsula; and a drongo, Dicruropsis pectoralis sirensis, 

 apparently nearest Dicruropsis pectoralis solombensis Oberholser from 

 Solombo Besar Island. 



On Pulo Kalambau, which is one of the three largest islands of the 

 Laurot group. Dr. Abbott landed for a day on December 7, 1907. 

 Here he collected two birds, one of them a new subspecies of white-eye 

 (Zosterops solombensis zachlora). 



From these incomplete collections the faunal relations of Solombo 

 Besar Island seem to be with Java and Timor; and of Mata Siri with 

 Borneo. H. C. O. 



ORNITHOLOGY. — The shedding of the stomach lining by birds, par- 

 ticularly as exemplified by the Anatidae. W. L. McAtee. The 

 Auk 34: 415-421, pis. 16-17. 1917. 

 The shedding of the stomach lining and its disposal by regurgitation, 

 in hornbills and a number of other birds, is well known. It is now 

 shown that this operation takes place commonly in many species of 

 birds, but that the process is usually one of gradual disintegration and 

 mixing with the food contents of the stomach. In this way the dis- 

 carded lining is ground up with the other food by the rotary move- 

 ment of the gizzard contents, and passed out of the body through the 

 intestines. This process has been observed in 24 species of ducks and.
