Family Soricidae 



Cryptotis parva 

 Least Shrew, Musarana 



Least or small-eared shrews of the genus Cryptotis are widely distributed in 

 eastern North, Central, and northern South America. The most widely distributed 

 species, C. parx'a, is distributed in eastern North America from southern Canada 

 through Mexico and Central America to the Chiriqui highlands of western Panama. 

 Although there are only a few specimens of Cryptotis parva known from Heredia 

 Province, we suspect that it is a common and abundant species on the western slope 

 of Volcan Barva in the Meseta Central. A single subspecies of C. parva, C. p. 

 orophila was recognized by Choate (1970) as occurring in Costa Rica. 



The specimens from San Jose de la Montana were captured in a home during 

 the months of September through November. The specimens from San Miguel de 

 la Montana were taken by house cats in an area that included small fmcas and houses, 

 but little natural vegetation. 



Specimens examined (6)— San Jose de la Montana, ca. 1,800 m [1 male, 

 2 females, KU]; San Miguel de la Montana, 1,690-1,700 m [1 male, 2 females, 

 KU]. 



Cryptotis sp. 

 Least Shrew, Musarana 



A single, long-tailed Cryptotis was captured in a pasture above Alto del Roble 

 northeast of Heredia, at 2,080 m by E. T. Hooper on 28 July 1968. He captured 

 this adult male shrew in a snap-trap baited with peanut butter and set in a stump. 

 It was originally identified as C. gracilis, and was reported as that species by Choate 

 (1970) and Hall (1981). It clearly is related to that species; however, it may repre- 

 sent an undescribed taxon. This specimen currently is under study by N. Wood- 

 man and R. Timm. 



Specimen examined (1)— Alto del Roble, 11 km NNE of Heredia, 2,080 m 

 [1 male, UMMZ].

Centronycteris maximiliani 

 Thomas' Bat 



Thomas' bats are found from Veracruz, Mexico, south through Peru and Brazil 

 (Fig. 10). The genus is monotypic (Husson 1978). Although Thomas (1912) 

 described Centronycteris centralis as a distinct species, Sanborn (1937) concluded 

 that it represented only the Central American subspecies of C. maximiliani. One 

 subspecies, C m. centralis, is found both in the Caribbean and Pacific wet tropical 

 lowlands of Costa Rica, but there are few specimens on record. 



Centronycteris maximiliani is uncommon throughout its range, and informa- 

 tion on its natural history is almost nonexistent. The known distribution suggests
