as small, relatively, as in Kiodotus ; inner lower incisors smaller, con- 
trasting with outer teeth almost as much as in Syconycteris , but sepa- 
rated in median line by a space equal to that occupied by each pair. 
Upper canines with broad, well-defined, longitudinal groove on 
anterior face, bounded on each side by a sharp ridge; cingulum ill 
defined; no trace of secondary cusps. Lower canine with barely 
indicated furrow on outer side. Anterior upper cheek tooth ( pm 2 ) 
scarcely larger than incisor, close to base of canine. Anterior lower 
premolar (pm, 2 ) considerably larger than corresponding maxillary 
tooth (its diameter about twice that of i 3 ), but similarly crowded 
against canine. Middle upper premolar (pm 3 ) conspicuously larger 
than the other cheek teeth, separated from pm 2 and pm 4 by spaces 
slightly greater than length of its alveolus. Other teeth essentially 
as in Kiodotus.
