surface, 4 May 1908, near Texel. 

 9, with black head, but having still the brown wingcoverts 



of the first plumage, 12 May 1908, near Texel. 

 cT, first plumage, 1 June 1908, near den Helder. 



165. Rissa tridactylus (L.). [Drieteenige meeuw]. 



We received only one specimen, a female, killed 3 De- 

 cember 1906 on the coast of Groningen. This gull is a 

 regular, though not common winter visitant. In the col- 

 lection van Wickevoort Crommelin is an old male, killed 

 in June 1840 at Zandvoort, Noord-Holland. 



166. Xema sahinii (Sabine). [Sabine's vorkstaartmeeuw]. 



We possess of this species a young specimen in first 

 plumage, that was presented to our collection in 1863 by the 

 late Professor van Lidth de Jeude of Utrecht. This specimen 

 is labelled by Schlegel »Mer du Nord" (Schlegel, Cat. Lari, 

 Larus sahinei, n*^. 2). It is an old, badly mounted example, 

 and as it is from the collection van Lidth de Jeude, in 

 which there were more rariora from the Netherlands, it is 

 very likely, that the specimen has been killed in our 

 country and that it is the very bird mentioned by Temminck 

 in 1840 as 5.un jeune sur les cotes de Hollande" (Man. 

 d^Orn. 2e ed. IV, 1840, p. 489). 



In the Museum of the Zoological Garden at 's Gravenhage 

 is a young male of this species, that has been shot on 

 the shore near Hoek van Holland, 11 October 1892. 



167. Hydroprogne tschegrava (Lepechin). [Reuzenstern]. 



Of this in our country very rare species we possess two 

 specimens: an adult one in winter plumage, not sexed, 

 shot long time ago in autumn on Texel, very probably by 

 Temminck, and an old female in summer plumage, shot 

 28 June 1847 on the Zijl, near Leiden, by H. Schlegel.
