Scatterplots of quantitative variables for Cryptotis nelsoni, C. mexicanus and C. parvus pueblensis and specimens collected in the most recent exploration in Los Tuxtlas, a new record for C. nelsoni (NR). Condylobasal length versus height of coronoid process (A) and length of molariform tooth row versus breadth of palate across second molars (B) corroborate the identification of the new records as C. nelsoni.
