APPENDIX TO CHECK LIST. 135 
varietally distinct from the European (see Ridgway, Am. Nat., viil, 
1874, 109). 
401. AEGIALITIS CANTIANUS (Lartu.), 
var. NIVOSUS (Cass.) Ridgw. 
Snowy Plover. 
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. HUDROMIAS MONTANUS (Towns.) HarTING. 
Mountain Plover. 
No. 415a. It is not necessary to recognize this even by varietal 
name; ‘‘ YM. 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 Hreunetes pustllus, 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. Bischoff, and should be added to the last as a straggler. 
[442bis.] NUMENIUS FEMORALIS Pratt. 
Bristie-Dbellied 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 J. thalassinus. According to this 
determination our species would stand as follows :— 
445. IBIS FALCINELBUS Auvcr. 
Glossy Ibis. 
445bis. IBIS GUARAUNA (Linn.) Ripa. 
Wihite-faced Ibis. 
445ter. [IBIS THALASSINUS Ripe. 
Q 
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.
