Ameritella agilis (Stimpson, 1857), Northern Dwarft Previously Angulus agilis (Stimpson, 1857)
April 1, 2016 – Harry Lee notes that “most of the New World spp. previously assigned to Angulus Mühlfeld, 1811, are now considered an exclusively Indo-West Pacific group, … are now placed in Ameritella Huber, Langleit, and Kreipl in Huber, 2015*.” Among them is Angulus agilis. So, in books, papers and data bases you might peruse published or updated since 2015, you may find this species identified as Ameritella agilis. In the interest of continuity and ease of reference for those relying upon older references, and to minimize my workload, I am refraining from updating to this name until this change has been more widely utilized.

2/1/15: After viewing this presentation Ron G. Noseworthy reported:
"When I was living in Newfoundland and collecting there, I obtained several lots of Tellina agilis, both living and dead. So, the northernmost range of this species also extends to the south coast of Newfoundland."
