Dr. Pellegrin has observed, on specimens from Lake Menzaleh, that the female 

 takes charge of the eggs and young in the same manner as T. nilotica. A specimen 

 195 millimetres long had the pharynx closely packed with about two hundred embryos 

 measuring 8 or 9 millimetres. Another specimen, 210 millim. long, carried about 

 one hundred to one hundred and fifty eggs. Dr. Pellegrin has also pointed out the 

 fact, which I have been able to verify in other species, that such nursing specimens 

 may have ripe eggs in the ovaries, so that the release of the young from parental care 

 is soon followed by another brood. 



Mr. Loat observes that, speaking generally, the fishermen of the Nile recognize only 

 one kind of Tilapia (" bolte "), but at the large lake or Birket Karun in the Fayum 

 they distinguish two, viz. T. galilcea as " bolte malowi" {^y* L5 ^) 9 and T. nilotica as 

 " bolte sultane " (^JlkU J^l). 



In one of the tombs of Deir el Gebrawi, this Tilapia is represented in perfectly 

 recognizable manner beside T. nilotica *.
