Artibeus toltecus toltecus (Saussure, 1860)
_Specimens._--_Matagalpa_: Santa María de Ostuma, 1250 m, 5; 2 km N, 6 km E Esquipulas, 960 m, 1.
This bat has been reported from Nicaragua previously by Andersen (1908:300) and Davis (1969:28), based on a total of four specimens. We netted this species at Santa María de Ostuma in patches of cloud forest at a cafetal. The specimen from near Esquipulas was taken in a net placed across a trail in second growth forest. Two females collected on 11 April and one taken on 30 June were pregnant (embryos 21, 26, and 12 mm, respectively, in crown-rump length). Testes of a male netted on 14 March were 7 mm in length, whereas those of two obtained on 11 April measured 4 and 7 mm. Selected measurements of our six specimens are given in Table 2.
_Specimens._--_Chontales_: 1 km N, 1.5 km W Villa Somoza, 330 m, 3. _Nueva Segovia_: 7 km N, 4 km E Jalapa, 600 m, 1. _Zelaya_: Bonanza, 850 ft, 6; S side Río Mico, El Recreo, 25 m, 6; Cara de Mono, 50 m, 1.
Davis (1970a:393-394) recently reviewed the systematic status of this small fruit-eating bat and recorded specimens from southeastern Nicaragua; the species was first reported from the country by Andersen (1908:290), based on a specimen from the Escondido River. Our additional material reveals that _A. watsoni_ occurs throughout eastern Nicaragua, the specimen from Nueva Segovia extending the known range as mapped by Davis (_loc. cit._).
A female from Bonanza (23 February) carried an embryo 14 mm in crown-rump length, whereas one from El Recreo (26 February) was not reproductively active; one of two females netted near Villa Somoza in early August was pregnant (embryo 21 mm in crown-rump length). Seven adult males collected in late February and early March had an average testicular length of 5.9 (5-7) mm; testes of two adults taken in late June and one captured in early August all measured 5 mm. The testes of young males (grayish pelage, partially unfused phalangeal epiphyses) were 2 or 3 mm in length.
