. Bonner zoologische Monographien. Zoology. 46. 10 mm : Lionycteris spurelli, skull a: lateral view, b: basal view, c: dorsal view, d: frontal view Skiill descriptions of the single genera Lionycteris () L spurrelli: Skull: rostnmi relatively short, approximately limited to one third of total length; distally flat and tapering. In lateral view, tlie upper incisivi continue tlie outline straightly. In basal view the palate is pomtedly trapezoid, width over the last molars considerably exceeds the distance of the canmi to each other. Choanae situated quite anterior with the palate reachmg only half the basal length. Praesphenoid outlined but without ridge, basisphenoid witli strong convexities (basisphenoid pits). Pterygoids witli hamuli ending shortly and pointedly, no pterygoid wings. No zygomatic arches. Teeth: dental formula - 2 3 1 - - 3 4 5 6 7 12-1-234567 Incisivi present m the upper and lower jaw; the upper ones being orientated anteriorly, iimer incisivi considerably larger than outer ones, long and spatular, with smooth edge, the outer ones only one tliird the size, pointedly trapezoid ("tomahawk"), producing an oblique edge which complements with those of the hmer incisivi to an edge formed like a horseshoe. Canmi strong, with cingulimi. Premolars canmifomi, anterior premolar separated from canine tooth by distmct diastema. Molar teeth quite strong with broad crowns and dilambdodont ectoloph; anterior molar larger than the middle one, tlie posterior one being the smallest. Lower incisivi of same size, forming a closed row between the canini. Lonchophylla (figs. 26-28) Skull: similar to Lionycteris; in smaller forms the rostrum is distinctly less than half of the total skull length, in larger species ahnost half of it. Skull laterally stretched, only weak.
