132 REPOKT OF NEW JERSEY STATE MUSEUM. 



246 Ereunetes pusillus (Linnaeus). 

 Semipalmated Sandpiper, Peep, Oxeye. 



PLATE 21. 



Adults in spring. Length, 5.25-6.50. Wing, 3.65-4. Upper parts, black, 

 feathers edged with buff and strongly streaked with rusty ; rump, plain dusky ; 

 under parts, dull white, breast and sides spotted or streaked with dusky. 



In autumn. Above, plain ashy-gray ; below, unspotted. 



Young in first autumn. Similar to spring adults, but duller, and breast 

 washed with buff and unstreaked. 



Abundant transient, occurring in May, and from July 10th to Oc- 

 tober 1st. 



Occurs on the Delaware occasionally and at suitable places inland. 



This species is probably our most abundant migrant Sandpiper, but 

 it associates so intimately with the Least Sandpiper and resembles it 

 so closely that it is practically impossible to distinguish them in life, 

 so that statements made about one apply equally to the other. 



247 Ereunetes mauri Cabanis. 

 Western Sandpiper. 



Closely related to the Semipalmated Sandpiper of which it is the western 

 representative, and from which it may be told by its much longer bill .85 to .95 

 instead of .68 to .75 and by the greater amount of rusty edgings to the 

 feathers of the upper parts. 



The Western variety of the preceding, with which it occurs, more 

 or less regularly, in autumn. 



A specimen was obtained by Dr. W. L. Abbott in Cape May county 

 September 14th, 1880, and another by Mr. I. N. DeHaven at Atlantic 

 City May 17th, 1892. Mr. W. L. Baily 1 found it quite as plentiful as 

 the Eastern form on Two Mile Beach September 1st to 15th, 1895, 

 and secured twenty specimens.
