14 . Descriptions of New Species of Helicidcc. 



Macroramphus scolopaceus (Say) Lawrence. Uncommon 

 — saw but few of them. Those seen were at a salt pond, called 

 Aqua Nueva, in South Western Texas, at least one hundred 

 miles from the coast. 



Plectrophanes McCownii Lawrence. Procured two spe- 

 cimens on the Texas prairies. I fired at a flock of Shore Larks, 

 and found this bird among the killed. The Shore Larks rose 

 several times, and settled again before I fired. 



Tyrannula cinerascens Lawrence, Ash-colored Fly- 

 catcher. The only specimen procured was killed between San 

 Antonio and the Rio Grande, near a small water course.
