Other specimens of S. l. occidentalis were taken under the following circumstances: 17 km. SE Talpa, Jalisco (night of November 3-4, 1962)—nine individuals netted over the Río Mascota in "pine-oak zone" along with representatives of S. l. parvidens, Artibeus toltecus, Chiroderma salvini, Eptesicus fuscus miradorensis, Lasiurus borealis teliotis, and Rhogeëssa gracilis; 20 km. WNW Purificación, Jalisco (night of November 20-21, 1962)—two specimens captured in a mist net stretched beneath branches of a fig tree at the edge of the Río Jicote in which Glossophaga commissarisi, S. l. parvidens, Artibeus turpis nanus, and Artibeus lituratus palmarum also were taken; 4 km. N Durazno, Jalisco (nights of November 21-22 and 22-23, 1961)—11 specimens, of which 10 were females, netted in company with G. s. leachii, S. l. parvidens, A. j. jamaicensis, A. toltecus, Centurio senex, and L. b. teliotis over a stream in a small canyon that supported "fairly dense stands of very tall deciduous trees." Five of the 10 females from 4 km. N Durazno were pregnant; each contained a single embryo. Crown-rump length of the embryos averaged 26.8 (24-30) mm. No gross reproductive activity was evident in other females of S. l. occidentalis collected.
