 the islands. He had never been on these particular islands

 ones, but according to his experience in Africa this was most 

 unlikely to be the case. 



Mr. G. A. K. Makshall and Dr. Jordan commented on

PouLTON exhibited a female Promachus, of a species unnamed

 descombesi, Boisd., 7.30 a.m., Aug. 18, 1914, at Takdah
