Least shrew, Cryptotis parva
, in southwestern Kansas and southeastern Colorado.
The major species in the dry old field were Cryptotis parva
(16), Microtus ochrogaster (9), and Blarina brevicauda (7), Zapus hudsonius (3), and single individuals of Peromyscus leucopus, Synaptomys cooperi, and M.
Because of uncertainties regarding identifications in light of studies since the publications on the Sloth caves, specimens identified as Neotoma mexicana (Mexican woodrat), Cryptotis parva
(least shrew), and Sorex cinereus (masked shrew) from those caves were borrowed from the Vertebrate Paleontology Collection of Texas Tech University for restudy.
Four species are included as threatened by the Mexican Government (Choeronycteris mexicana, Leptonycteris yerbabuenae, Cryptotis parva
soricina y Romerolagus diazi).

nuttalli); seven species were known for the county by <3 specimens (Dasypus novemcinctus, Sylvilagus floridanus, Cryptotis parva
, Scalopus aquaticus, Sciurus niger, Microtus pinetorum, Peromyscus gossypinus); and four species had not been collected in the county in ca.
We captured less than five individuals of Baiomys taylori, Cryptotis parva
, Microtus ochrogaster, and Mus musculus (Table 1).

However, the number of crania of Cryptotis parva
extracted from the owl pellets (Table 1) is quite remarkable.
Reports of Cryptotis parva
extending its range into west-central Texas have increased considerably since Hall (1981) and Davis & Schmidly (1994) published their distributional maps of the least shrew.
Knowledge of the distribution of the least shrew, Cryptotis parva
, in Texas and New Mexico has increased markedly since the publication of Hall (1981).
In addition, remains of Cryptotis parva
were relatively common in the pellets; the least shrew has been considered previously as uncommon in this part of north-central Texas (Dalquest and Horner, 1984; Jones et al.
The following mammalian taxa were recovered: Cryptotis parva
(lower jaw); Perognathus sp.
Perhaps most notable are the two shrews, Cryptotis parva
and Notiosorex crawfordi.
