a. Like ácer are declined the following stems in ri-: -

• 

• alacer, campester, celeber, equester, palúster, pedester, puter, salúber, silvester terrester, volucer. So also names of months in -ber: as, Octóber (cf § 66).

  

NOTE 1: This formation is comparatively late, and hence, in the poets and in early Latin, either the masculine or the feminine form of these adjectives was sometime used for both genders: as, coetus alacris (Enn.). In others, as faenebris, fúnebris, illús tris, lúgubris, mediocris, muliebris, there is no separate masculine form at all, and these are declined like levis (§ 116).

NOTE 2: Celer, celeris, celere, swift, has the genitive plural celerum, used only as noun, denoting a military rank. The proper name Celer has the ablative in -e.
