494 bulletin: museum of comparative zoology. 



In the adults, irrespective of sex, the wing ranges from, 220-237 

 (226.63); the tarsus from 102-120 (112.4); the culmen from 60-62 

 (61.1). There is Httle doubt that females are smaller than males in 

 this as in most, if not all the species and subspecies of Stilts. Some 

 of the specimens unfortunately are almost certainly incorrectly 

 labeled as to sex. 



22. Numenius arquatus madagascaeiensis (Linne). 



Two adult females, Morondava, July 22, and Ambola, August 7. 



Van Oort (Notes from the Leyden museum, 1910, 32, p. 116), 

 has already pointed out that the Siberian Curlew winters in Mada- 

 gascar, and must bear the above name. Our two specimens are 

 distinctly referable to this form. Whether the differences are suffi- 

 ciently great or sufficiently constant to warrant subspecific recogni- 

 tion must be decided when sufficient material is available. 



23. Numenius phaeopus phaeopus (Linne). 



Two adults, one female, Tulear, August, one unsexed, without date. 



One of these, a very bleached out specimen, is referable to the west- 

 ern Whimbrel, the other is apparently an intermediate and might be 

 referred to either N. phaeopus phaeopus or N . phaeopus variegatu^ 

 (Scopoli) with equal chance of accuracy. 



24. Calidris leucophaea (Pallas). 



Two females, in winter plumage, on an island at Nosy Asatra, 

 southwestern coast, August 5, and Morondava, July 23. 



25. Erolia ferruginea (Briinnieh). 



Forty-eight specimens, Tulear, August 18. 



This series includes young of the year and adult birds with mottled 

 rufous and white under parts, in about equal numbers.
