APPENDIX TO CHECK LIST. 135 



varietally distinct from the European (see Ridgway, Am. Nat., viii, 

 1874, 109). 



401. ^GIALITIS CANTIANUS (LATH.), 

 var. NIVOSUS (Cass.) Ridgw. 

 Snowy IMover. 



No. 402*. As intimated in the text, the North American mountain 

 plover is perfectly distinct from the Asiatic. I have only lately seen it 

 in breeding dress : it has no black pectoral band, but a transverse 

 black coronal belt and black loral stripe. 



402. EUDROMIAS MONT ANUS (TOWNS.) HARTING. 

 Mountain Plover. 



No. 415a. It is not necessary to recognize this even by varietal 

 name; " H. scolopaceus" being merely longer-billed specimens of M. 

 griseus, such as may be shot out of almost any flock of the latter. 

 The range of variation in length of bill is no greater than that occur- 

 ring in Ereunetes pusillus, as noted in the Key, p. 254. 



No. 442bis. A well known Pacific curlew, before overlooked in the 

 Smithsonian collection, was taken at Fort Renai, Alaska, May 18, 1869, 

 by F. BischofT, and should be added to the last as a straggler. 



[442bis.] NUMENITJS FEMORALIS PEALE. 

 Bristle-bellied Curlew. 



No. 445. According to Mr. Ridgway (Am. Nat., viii, 1874, 110), the 

 ordinary North American glossy ibis is absolutely identical with that 

 of the Old World. He, however, finds two other species in western 

 United States, /. guarauna and I. thalassinus. According to this 

 determination our species would stand as follows : 



445. IBIS FALCINELLTJS AUCT. 

 Glossy Ibis. 



445bis. IBIS GUAKATTNA (LINN.) RIDG. 

 White-faced Ibis. 



445ter. IBIS THALASSINUS RIDG. 

 Green Ibis. 



No. 448bis. I am informed by Prof. Baird that the Jabiru, of Cen- 

 tral America, was taken some years since at Austin, Texas. It should 

 enter the list as a straggler. 



[448bis.] MYCTERIA AMERICANA L. 

 Jabiru.
