220 The Wilson Bulletin— No. 69. 



7. Ereunetes pusillus. — Semipalmated Sandpiper. 



S. Pisobia ntiiiutilla. — Least Sandpiper. 



On August 31st a great number of these birds was seen and 

 a few were taken on this date at the Grand Reservoir. They 

 were very tame, allowing me to approach within three feet of 

 them while they were gleaning along the sandbanks. The 

 best diagnostic feature between Ereunetes pusillus and Piso- 

 bia minutilla to my observation is the color of the legs, these 

 being dark in pusillus, light in minutilla. 



9. Hydrochclidon nigra surinamensis. — Black Tern. 



A young male was shot by me on August 31st at the Grand 

 Reservoir, proving that this species is a regular, though rather 

 rare, migrant in Western Ohio. 



10. Calidris arenaria. — Sanderling. 



On September 24th, at the Grand Reservoir, about fifty 

 birds of this species were seen, six of which, four females and 

 two males, were secured. This, I believe, is the first time that 

 such a great number of this species has been observed so far 

 in the interior of Ohio. Records along the Lake Shore are 

 common, but inland mostly solitary birds were recorded in the 

 past, and even at Detroit the first appearance was noted Au- 

 gust, 1908, (Auk, October, 1909, page 427) by a member of 

 the Wilson Club. All such records should be placed in the 

 Wilson Bulletin as the best organ for ornithologists of the 

 Middle West. 



11. Charadrins dominicus. — Golden Plover. 



Shot a female September 24th at the Grand Reservoir from 

 a flock of nine. A male was killed October 16th at the Lora- 

 mie Reservoir and sent to me, proving again that this species 

 is a regular migrant across this section of the country. 



12. Afarera ainericana. — Baldpate. 



A flock of six was seen at the Grand Reservoir September 

 24th, 1909, my first fall record in the State.
