In Class. Quart. XV. 193 Dr. Mountford discussed a quotation from the Grammarian Caper in the Liber Glossarum (s.v. Lacteus), and referred it to an item culled from Vergil Scholia by the Abstrusa Glossary. Since Keil in his edition of this grammarian (Gram. Lat. VII.) did not know of this glossary evidence to Caper's text, it may be worth mention that another Caper quotation appears in Lib. Gloss., s.v. Kaluus (properly Kalua or Calua). It is taken from the first sentence of p. 100 of Keil's edition, and shows that the words caluaria singulare have dropped out of the three Caper MSS. used by Keil, after plurale est, though they have left a trace in a variant (caluaria for calua) in two of the trio. And it testifies (rightly or wrongly) to the name of the historian who used caluaria ‘a skull.’ Here is the gloss as it stands in the two chief MSS. of the Liber Glossarum:

Kaluus:

кραѵоѵ uocatur, licet Celio et Varro kaluariam dicant; nam caluariae plurale est, kaluaria singulare.
