GeograpJt'u' (HsfriJ>i(tio)}.—Mainland of tropical and subtropical America. Niimljer of forms.—About half a dozen species of this genus have been described, CJuiraeters.—Teeth as in Rliynehiscas^ except that pm simple terete spicule, and the outer anterior cingulum cusp of m^ is less developed. Skull (fig. 14) with broad flat rostrum considerably more than half as long as brain case, and so low posteriorly as J:o form a dis- tinct angle with forehead. Sides of rostrum very slightly inflated and median groove obsolete. Lower rim of orbit so expanded as to hide tooth row wdien viewed from above. Pre- maxillaries large, exjoanded poste- riorly, and terminating on dorsal surface of rostrum by an abruptly truncate margin. Postorbital proc- esses large, broad, and flat. Brain case with distinct sagittal crest. Basisphenoid pits large, well de- x2. fined, separated in middle by a distinct longitudinal j^late. Audital bulla not as large as area of the pits, slightly but distinctly emar- ginate antero-internally. Externally dit-tingnished by the presence of a glandular sac opening on upper surface of antebrachial mem- brane close to forearm near elbow. The sac is conspicuous in males, less developed in females. Sjyecies examined.—Sact'opteryx hilmeata (Temminck), S. lepUira (Schreber), 8. canescens Thomas, S. yyninura Thomas, S. centralis Fig. 14.—Saccoptekyx bilineata. Caura, Trini
