From J. E. Gray [1845–75]
Bivalve have normally a series of 2 or 3 QQQQ teeth under the QQQQ and laminal lateral teeth
The lateral teeth are of sometime in arcadæ Nuculidæ divided across into numerous lobes looking like a series of transverse teeth interlocking into some others
I looked at series of Arcadæ, & a good series from teeth at QQQQ withQQQQ ligament to QQQQ row of QQQQ—
But this case not good to quote.
Lateral teeth in Arcadae.
