| The present authors independently from one another studied oological material from Java. The results of their studies are combined in the present paper. Hellebrekers deals with three collections, held by the Rijksmuseum van Natuurlijke Historie at Leiden, brought together (a) by M. E. G. Bartels and his sons (4770 shells), (b) by J. G. Kooiman (280 shells), and (c) by H. J. V. Sody (175 shells). Of these collections those made by Bartels and Sody consist almost exclusively of eggs from West Java, while that made by Kooiman originates from East Java. Hoogerwerf gives details of 1020 shells of his own collection, almost all of which originate from West Java. These were obtained after the appearance in 1949 of a paper in which he published the colour... |

| In a previous paper (Hellebrekers, 1942) I stated my intention to give some more details on imperfectly known eggs, based on material of the collection of the Penard's. The description of these hitherto imperfectly known or incorrectly described eggs will be strongly aided by the coloured plate accompanying the present paper, this plate represents a number of eggs of four species of birds from Surinam, of each species such eggs are figured as to show the variation in shape and colour. Moreover I have the opportunity to give a number of corrections concerning some of the data given in my previous paper. When the latter appeared I sent a copy to Mr. M. Schönwetter, one of the foremost living authorities in oölogy, asking him for a critical comment on my... |

| In 1910 the Rijksmuseum van Natuurlijke Historie at Leiden obtained the important egg collection from Surinam, brought together by Messrs. F. P. and A. P. Penard. Owing to different circumstances this collection as a whole was not studied again, and, with the exception of some notes in papers by Schönwetter (1932, 1933) nothing has been published upon the material since it came into the Museum. In 1941 and 1942 I had the opportunity to rearrange the oölogical collections of the Leiden Museum, and during this work the Penard material was incorporated into the general collection. During my study of the material I became convinced that it is worth while to publish more detailed data than those contained in the works of the Penard's. This especially holds as... |
