ANOMIIDiE. 
E. S. Morse has observed that the very young shell of An&mia is 
rather regular and imperforate, and that the perforation begins 
at the lower margin of the right shell as a notch caused by the 
issue of the byssus, which, being afterwards encircled by the new 
growth of the shell, becomes finally a foramen, and is pushed by 
further grow th nearer the umbones. Am. Nat. v. Sept. 1871,
