Frenula jtffreysi^ described as new genus by Dali, Am. Nat. v. (1871), p. 55^ 
is very probably founded on a specimen the septum of which was broken 
away, and may belong to the section Ismenia, of the genus Megerlia : Dali, 
Am. J. Conch, vii. p. 66, pi. 11. figs. 7-10. 
riatidia davidsoni (Eudes-Deslongchamps), hitherto only known from the 
Mediterranean, has been found on the Atlantic coast of France, near Cape 
Breton, and is accurately described by P. Fischer, J. de Conch, xx. pp. 160- 
164, pi. 6. The perforation lies only in the dorsal valve, the ventral being 
provided with a rather projecting summit, with the deltidium behind the 
perforation, in opposition to the other articulated Brachiopods. The peduncle 
is very much shortened ; and the dorsal valve comes into immediate contact 
with the substance to which the animal is attached, resembling in this re- 
spect the perforated valve of Anomia.

Glottidia. The laminoe supporting the posterior retractor or adjustor 
muscle are the internal, not the postparietals. To this genus belongs lAn-

palmeri, sp. n.. Gulf of California. Dali, 1. c. pp. 77, 78, & 54.
