 Meridian, 1886 : a perfect right valve of a small Tellinid which corres- 

 ponds remarkably well with Meek's figure of the above-named species. 

 In the sjDecimen collected by Mr. Tyrrell, however, only the outer sur- 

 face is exposed to_view, the whole of the interior being buried in the 

 matrix. No traces of any radiating strife can be discovered on its 

 test, with a lens, although the markings on its outer surface are beau- 

 tifully preserved, and its test does not appear to have been " very thin."
