 individual. The beak is relatively longer. I regard it identical with 

 8. t'icuxi, and have included it in the table of measurements under that

 entirely satisfactory. This skull also agrees well in proportions and 

 details of structure with that tigured by Van Beneden and Gervais 

 under the name of ;S^. pallida (Osteographie, pi. xlt, fig. G).
