144 Messrs. A. and E. Newton's Observations 



1 16. Prairie Warbler. Dendroeca discolor (Vicill.), Baird ; 

 Sylvia minuta, Wils. pi. 25. fig. 4. S. discolor, Aud. pi. 14. 



Leaves the island for a few months in summer, but is rather 

 common during the time it is resident. 



" I observed this bird last on March 27th, and saw it again 

 Sept. 10th.''— E. N. 



17. Cape-May Warbler. Dendroeca tigrina (Gm.), Baird ; 

 Sylvia maritima, Wils. pi. 54. fig. 3 ; Aud. pi. 414 ; d'Orb. Voy. 

 de I'ile de Cuba, Ois. pi. 10. Certhiola maritima, Gosse, 111. B. 

 Jam. pi. 17. 



Not at all common ; only a winter visitant, and leaving earlier 

 than any other of the migrants observed by us, having, it would 

 appear, a longer journey than most of them to perform. 



"lam compelled to difi"er from Mr. Gosse (B. Jam. p. 87) 

 in the decision he has arrived at about this bird being a Cer- 

 thiola. When I first arrived in St. Croix I had the opportunity 

 of observing its manners for several days ; and they were alto- 

 gether those of a Dendroeca. I further took particular care, not 

 only to examine while fresh, but also to preserve, the tongue 

 of a male which I shot on March 19th, 1857. This is now be- 

 fore me ; and 1 am able to compare it with the tongues of Cer- 

 thiola, Mniotilta, and Dendroeca cestiva. That of Certhiola is, 

 besides being penicillate, deeply bifid. Now there is nothing of 

 this conformation in any of the others. Of these, it is true that 

 D. tigrina has the most bushy pencil of hairs at the tip ; but 

 Mniotilta and Parula come very near it in this respect : and it 

 is also true that D. (estiva differs from these three in having a 

 horny point. If any deduction is to be drawn from the charac- 

 ters of the tongue, D. tigrina must be (and very likely should 

 be, on other grounds) removed from the genus Dendroeca, but 

 certainly not placed in Certhiola." — A. N. 



18. Redstart Flycatcher. Setophdga ruticilla, Bp. ; Mus- 

 cicapa ruticilla, Linn. ; Wils. pi. 6. fig. 6 ; Aud. pi. 40. " Red- 

 start." 



This beautiful species, having at first sight so much the ap- 

 pearance of the European Redstart [Ruticilla phoenicur a, Bp.), is 

 very common in the spring of the year, and especially seen about
