FIG. 18. Occlusal views of upper molars of Hypsiprymnodon moschatus (A, AMNH 160120 [right M1]), Caenolestes fuliginosus (B, BMNH 1954.295 [left M2, reversed]), and Acrobates pygmaeus (C, AMNH 37185 [right M2]). General features of upper molar crown morphology discussed in the text are illustrated, as are characters 132, 133, 136, 137, 140, 141, 143, 144, 145, and 146 (see main text for description of these characters and character states), as follows: Hypsiprymnodon moschatus 132(-), 133(0), 136(2), 137(1), 140(-), 141(0), 143(1), 144(1), 145(-), 146(-); Caenolestes 132(-), 133(1), 136(2), 137(-[but note that some Caenolestes specimens retain a paracone and can be scored as 1]), 140(-), 141(0), 143(1), 144(0), 145(-), 146(-); Acrobates 132(-), 133(1), 136(2), 137(-), 140(-), 141(0), 143(1), 144(0), 145(-), 146(-). Abbreviations: mec, metacone; nci, neomorphic cingulum; pac, paracone; stB, stylar cusp B; stD, stylar cusp D. Teeth are not shown to the same scale.
