OF THE NETHERLANDS. 



163 



metatarsus 51, culmen 26 mm. For comparison I had six 

 specimens of barbarus in our collection (Schlegel, Cat. Fal- 

 cones, Falco barbarus, n os . 1 to 5, and a young specimen 

 from the Red Sea); apart from the markings on the under- 

 surface our specimen agrees tolerably well with n°. 4 of 

 the Catalogue, an old specimen, not sexed, from Sennaar. 

 Our specimen is the only one known to me from the Nether- 

 lauds, the specimen under the name of barbarus in the 

 collection of the Zoological Garden at Amsterdam, caught 

 2 October 1886 at Cromvoirt, Noord-Brabant, being in my 

 opinion a young peregrinus, a female of small size (wing 

 315, tail 170, tarso-metatarsus 50 mm.) with not very broadly 

 striped underparts. 



90. Falco subbuteo L. [Boomvalk], 



Three young specimens, killed in September at Zoeter- 

 woude, Wageningen and Groesbeek. 



91. Falco merillus (Gerini). [Smelleken]. 



We received 15, all young specimens, viz.: 2 males and 

 10 females from Harderwijk, Gelderland, October 1907, one 

 male 25 October 1907 from Egmond-Binnen, Noord-Holland, 

 and two females 11 January and 25 January 1908 from 

 Texel. 



92. Cerchneis tinnunculus (L.). [Torenvalk]. 

 8 specimens. 



93. Erythropus vespertinus (L.). [Roodpootvalk], 



We possess no specimen from our country. This species 

 only once has been killed in the province Limburg in May 

 1901 (Snouckaert, Tijdschr. Ned. Dierk.Ver.VII, 1902, p. 266). 



Pandionidae. 



94. Pandion haliaelus (L.). [Vischarend], 



An adult female was caught near the polder ,,het Noorden" 

 on the island of Texel on May 9 th 1907 and purchased
