The ears are usually smaller, however, and are never joined across forehead. The skull of Mormopterus minutus is shown in fig. 44. Species examined. â Mormopterus acetabulosus â (Demarest), M. alli- oenter ( D o b s o n ), M. jugularis (Peters), M. kalinowskii (Thomas), and M. minutus (Miller). Remarks.âThe constant absence of the small upper premolar and the generally smaller size of the ears as compared with those of Nyctinomus seem important enough characters to warrant the recognition of this genus. In the two known American species there are only 2-2 lower incisor Fig. 44.âMormopterus minutus. Adult male., Trinidad, Cuba. No. 4915. Amer. Mus. Nat. Hist, x 2}. Genus PLATYMOPS Thomas. 1900.
