Small-eared shrews of the New World genus Cryptotis (Eulipotyphla, Soricidae) comprise at least 42 species that traditionally have been partitioned among four or more species groups based on morphological characters. The Cryptotis mexicana species group is of particular interest, because its member species inhibit a subtly graded series of forelimb adaptations that appear to correspond to locom...

•The name Cryptotis peregrina (Merriam, 1895) previously encompassed two separate populations of a small-eared shrew of the Cryptotis mexicana-group inhabiting the Sierra de Cuatro Venados and the Sierra de Miahuatlan in Oaxaca, Mexico. Analysis of museum specimens from these two populations, including the type series of C. peregrina, indicates that they are neither conspecific nor even sister ...

•Populations of small-eared shrews inhabiting the northern Cordillera Oriental of Colombia and adjoining Venezuelan highlands in the vicinity of Páramo de Tama have been referred alternatively to Cryptotis thomasi or Cryptotis meridensis. Morphological and morphometiical study of this population indicates that it belongs to neither taxon, but represents a distinct, previously unrecognized speci...
متن کاملSurvival of the less-fit: a least shrew (Mammalia, Soricidae, Cryptotis parvus) survives a separated leg fracture in the wild.
X-rays of the deformed femur of a least shrew (Cryptotis parvus) revealed an ossified callus enclosing a greatly displaced, spiral fracture. Based on models of fracture healing, this shrew lived for at least 28 days postfracture. Survival of major fractures in the wild may not be uncommon.
