Nothing of the nature of Sorby^s lichnoxanthin was found 

 in any shell. 



All flesh-coloured, olive, leather-coloured eggs, and all which 

 are spotted with red, brown, black, or grey, contain oorhodein, 

 generally, however, with traces of oocyan. It is therefore 

 probably nearly universal, except among certain Crypturi. In 

 the shell, oorhodein is generally in the deeper, oocyan in the 

 more superficial layers. 



119. Kutter on Philippine Birds. 



[Beitrag zur Ornis der Philippinen. Von Dr. Kutter. Separatabdr. aus 

 Cab. J. f. Orn. 1883.] 



Dr. Kutter's contribution to Philippine ornithology is 

 based upon a collection made by Herr O. Koch and Dr. A. 

 Schulenberg in the vicinity of Sibulan, in South-eastern Min- 

 danao. Fifty species are represented in the series, whereof 

 one (previously described in Orn. Centralbl. 1882, p. 183, as 

 Graucalus kochii) is new to science and seven are hitherto un- 

 recorded in ]\Iindanao. Many interesting notices both by 

 collectors and the author are given.

[Descriptions of new Species of Birds of the Genera Chrysotis, Formici- 

 voi-a, and Spermophila. By George N. Lawrence. Annals N. Y. Acad. 

 Sc. vol. ii. p. 381.] 



The island of Aruba, West Indies, has yielded a new 

 species of Parrot {Chrysotis canifrons), the distinguishing 

 character of which is the ashy front and throat. Unfortunately 

 the skin of the example, which was brought home alive, has 

 not been preserved. Formicivora griseigula, from British 

 Guiana, is a second new species ; and the third is Spermophila 

 parva, from Tehuantepec, Mexico.
