 belly and throat furrowed. Sometimes there are white spots on the 

 side. 



" The first Whales appear in the Abrolhos waters at about the end 

 of May, and they stay until October. The females often bring young 

 calves with them, and appear to seek the shelter of the reefs. The 

 headquarters of the Abrolhos fishery is at Caravellas, or, rather, at 

 the mouth of the river Caravellas, where are situated the armagoes 

 or trying-houses." — E. Hartt, Geology and Physical Geography of 

 Brazil, p. 182. 



" The fishery begins at Bahia, according to Castelnau (Expedition 

 dans I'Amerique du Sud, tome i. p. 750), about the 13th of June, 

 and lasts till the 21st September. At Caravellas I was assured that 

 the Whales always appeared later than at Bahia, and the fishery does 

 not always begin until the last week in June, continuing through 

 the mouth of September." — E. Hartt.
