 (Smith); Blackhawk (Walters). 



104. (247). lircunctcs occidoita/is Lawrence. Western Senii- 



pahnated Sandpiper. 



This species closely resembles the preceding, Init differs in hav- 

 ing richer chestnut or rusty tints on back, and averaging slightl}^ 

 larger. Though called a western variet5^ it ranges to the Atlan- 

 tic coast, in company with piisi//us. Coues' Key gives the average 

 length of bill as .66-. 87 ior pusi/ius, and .85-1- 15 for occidcntalis. 

 Two specimens in the University museum, males, were taken at 

 Burlington by Paul Bartsch, October 15, 1895; No. 16363, bill .96 

 inch; No. 16364, bill .95 inch. 



The .species is probabl}' more common than the Iowa records 

 would indicate, but the bird must be taken to be identified and is 

 apt to be confu.sed with the preceding. Both species are too small 

 to be considered as "game birds," and are seldom shot. 



Genus Calidris Cuvier. 



105. (248). Calidris arcdaria (Linn.). Sanderling. 



The Sanderling, a typical beach bird, is instantly recognized by 

 its having no hind toe. The species is irregularly distributed in 

 Iowa, being reported by only a few observers. Keyes and Will- 

 iams stated that it was "not common. Occurs during migrations 

 about the lakes of northern Iowa" (Bds. of Iowa, 1889, 122). In 

 Nebraska it is "an irregular migrant, .sometimes numerous; re- 

 ported from Omaha by Trostler and Skow" (Rev. Bds. Neb., 41). 



County records: Des Moines — a female specimen, juv., taken 

 at Burlington October 15, 1895, by Paul Bart.sch; Mus. Nat. Hist. 

 No. 16339. Lee — "flocks are not rare about the middle of Sep- 

 tember. Earliest dates August 24; latest September 10. I have 

 no spring records; Keokuk district" (Praeger). Linn — "rare 

 migrant" (Berry). Mills-Potta\yattamie — "common migrant" 



(Trostler). 



Genus Limosa Brisson. 



106. (249). IJinosa fedoa (Linn.). Marbled Godwit. 



The Marbled Godwit, the largest of the Ba}' Birds excepting 

 the Long-billed Curlew, breeds chiefly in the interior of North 

 America. It was formerl}- a tolerably common migrant in Iowa
