that it is limited to lowland tropical rainforest. Both Goodwin (1946) and Albuja 

 (1983) reported Ecuadoran specimens taken from tree holes. Although no data have 

 been reported, C. maximiliani is almost surely insectivorous (Wilson 1973a). LaVal 

 (1977) found pregnant females in May and subadults in September at La Selva, 

 suggesting the monestrous pattern common to other emballonurids (Wilson 1973b). 



The first Costa Rican specimen of C maximiliani came from La Bijagua, on 

 the Caribbean slope of Volcan Miravalles in Alajuela Province (Allen and Bar- 

 bour 1923). Additional specimens were collected on the Osa Peninsula (Gardner 

 et al. 1970; Starrett and Casebeer 1968). LaVal (1977) captured four individuals 

 at La Selva in 1973. LaVal also observed a single individual roosting 12 m up 

 on a tree trunk at Carrara Biological Reserve, in tropical moist forest on the Pacific 

 slope. 



Specimen examined (1)— Finca La Selva, 3 km S of Puerto Viejo, 70 m
