2 Till se measurements are not only those of United States and .Mexican exiunplcs, but also of 

 Middle .\muricau examples (" siirilidiilii.s," .SeLA'rKli, and "jileliciuti," C'aiianis), and of a scries 

 from Kcuador and New Granada {= " Inxjotoisis," .Sci.atei!). In eoinpariiig a ipiite largi' 

 niimbcr of smh Middle ,\meiican and Ivjuatorial s]ieciinens with the large series of Xortlicin 

 examples, we have been utterly unable to appreciate even the slightest dill'erelicc between thciii. 



The ('. /iiiiKjisis (Lawi;. Ann. N. Y. Lye. l.\, l.S(ill, '2:i7 ; Puna Island, (luayaipiil) is foiiiidccl 

 upon ail iiiimaturi! sjicciiiieii, so tlii^ characters of the species cannot be given with exactness. 

 The relatioMsliip apjicars very close to the ''. eiiribtrim, there being the same large, very depressed 

 bill, with the long bristles reaching nearly to its tip, and the tail about as long as the wing ; 

 while the npiicr i>liimage has the light faint transverse mottling seen in the young mrihtfitx, var. 

 /i(i/iii)nciinis, and the lining of the wing ochraccons. In colors, however, the two are very diller- 

 eiit, the young of y<i//«H.s/.s- being ashy-green, instead of pure ash, (Ui the back, the crown very 

 mmh darker, instead of not a|iprccial)ly so ; the wing-bands are white instead of ochraccous, 

 wbili^ the breast and sides are dull suliihnr-yellowish, instead of ashy, without any yellow tinge. 

 The measurements are as follows : Wing, 2.60 ; tail, 2.60 ; culr.icn, .72 ; tarsus, ..'i6. 



The a. ni'hrmrus, Sci.atkr k Sai.vix (V. Z. .S. 1860, 419 ; Saj.v. Ibis, 1870, 11.1), of Costa 

 Itica, we have not seen. From the description, however, it seems to bo scarcely dilfercnt fidin 

 V. liKiiihrin, and it is ])robably the same. The size (wing, 3.30) appears to be a little smaller, 

 and the belly more deeply yellowish.
