No specimens of these large and richly colored elephant-shi-ews 

 were obtained by the Smithsonian African Expedition. The single 

 specimen in the museum was collected in the coast region near 

 Mombasa by the Rainey Expedition in 1911. The animals are 

 evidently difficult to secure, or are much restricted m their dis- 

 tribution.
