Prof. Blasius published his first paper on Grabowsky's 

 Boruean bird-collections in the ' Verhandlungen der zoolo- 

 gisch-botanischen Gesellschaft ■" of Vienna (1883, pp. 1-90). 

 Grabowsky has since then shifted his quarters, and sent home 

 altogether 85 more bird-skins, which have been already partly 

 reported on at a sitting of the ' Verein f iir Naturwissenschaft ' 

 of Brunswick. Prof. Blasius now describes the new district 

 visited by Grabowsky at some length. It lies up the Negara, 

 a confluent of the Bareto, in Eastern Borneo, and is shown 

 in Carl Bock's map. A list of about fifty species, to which 

 the birds represented in Grabowsky's last collection are 

 referable, follows, and special remarks upon some twenty-five 

 of these. Near Mindai, Grabowsky found Mach(srhamphus 

 alcinus breeding, and shot one of the pair off" the nest, which 

 was placed on a lofty tree, but was unfortunately empty. 



54. W. Blasius on the Breast-bone of Birds. 

 [Ueber Vogel-Brustbeine. Idem. Tom. cit. p. 228.] 



This is an abstract of a paper read before the German 

 Ornithological Society at their Meeting in Oldenburg. Dr. 

 Blasius, who had long made the sterna of birds a special 

 object of study, found in the series of the bones accumulated by 

 Dr. Finsch during his recent travels in the Pacific many forms 

 of great interest, and makes special remarks on the sterna 

 of Scythrops, Nestor, Ptilorhis, Esacus, and Dendrochelidon.

This third recent contribution (c/. ' Ibis,' 1884, pp. 205 &

 mens which have changed hands.
