AVIFAUNA 



Procellariidae. 



9. Fulmarus glacialis (L.). [Noordsche stormvogel]. 



This is a rare visitor to Holland. Most of the specimens 

 are killed in the cold season after stormy weather. Last 

 year, however, a female was captured alive on the Vliehors 

 near Texel on the 23 rd July. The primaries of the right 

 wing had not attained their full length, so that the bird 

 was not able to fly. 



10. Procellaria pelagica L. [Stormvogeltje], 



This species has become in later time in Holland much 

 rarer than formerly, when it was commoner than the next 

 species. In 1863 Schlegel recorded in the Catalogue of the 

 Procellariae three specimens killed in Holland and no spe- 

 cimen of Oceanodroma leucorrhoa. In the collection van 

 Wickevoort Crommelin are 6 examples of pelagica and only 

 2 of leucorrhoa. The Museum has not received this species 

 during the last four years.
