have to be restricted to intra- and intergeneric allometries. Tliese, however, are quite 

 suitable to give evidence of structural morphologic pecuharities and systematic relations 

 in different genera. 



Regression (represented by the reduced major axis) was calculated with reference to the 

 measure SIZE for the following skuU measures: 



- Width over canini (CC) 



- Upper tooth row (OZR) 



- Length of palate (GL) 



- Mandible length (UKL) 



- Coronoid height (CH) 



The formulae are given in detail in Rempe (1962). 



The following tabular sunmiaries show arithmetic mean values of both parameters as 

 logarithms, the gradient (tan alpha) of the reduced major axis in a double logarithmic 

 system of coordinates, the correlation coefficient (r) and the distance of the log. mean 

 value to the reduced major axis of the outgroup ("Lot") for each genus examined (tab. II- 

 IS). In the graphs the reduced major axis for the outgroup {Carollia and Phyllostomus 

 calculated as a unified common sample) is drawn as a broken line. The coordinate 

 resulting from the mean values for both parameters is marked as a point. In case the 

 correlation can be secured by the size of the random sample, the reduced major axis of the 

 respective nectarivorous genus is represented as a straight line scoring the coordinates of 

 the mean value (fig.50-54). 



The generic names are placed aside to the mean value coordinates (An = Anoura, Bp = 

 Brachyphylla, Ca = Carollia, Cs = Choeronisciis, Ct = Choeronycteris, Ep = Erophylla, 

 Gp = Glossophaga, Hn = Hylonycteris, Lc = Lichonycteris, Le = Leptonycteris, Li = 

 Lionycteris, Ps === Phyllostomus, Pn = Phyllonycteris, Lp = Lonchophylla, Mp = 

 Monophyllus, Ms = Musonycteris (C. harrisoni), Pn = Phyllonycteris, Ps = Phyllostomus, 

 Pt = Platalina). 



A synopsis of the calculated distances to the outgroup is given in tab. 16. Diagrams with 

 individual values and - if available - distribution ellipses for each genus do exist and can 

 be ordered from the author.
