and skeletons from this region. Some observations on the natives' hunting and 

 use of the species are given. 



1930. — Schouteden (p. 370) states that the manatee is found in the lower Congo 

 only and that it seems to be particularly localized in the region about Boma. 



The single specimen of a manatee collected by the Congo Expedition 

 was taken by Mr. Lang at Banana, in August, 1915. Photographs of 

 this animal are reproduced here as plate XXVII. 



Angola 



1746. — Barbot (pp. 517-518) describes the manatee from the lakes of "Angola, 

 Quihite, and Angolm in the province of Massingam," localities not appearing on any 

 maps that I have consulted. 



1920. — Possibly on information obtained from sources here quoted, Marquardsen 

 (p. 69) writes of the occurrence of manatees in Angola rivers. 



Loje River: 1875. — Monteiro (p. 17) had part of a specimen from near Ambriz 

 at the mouth of the Loje. 



Dande River: 1875. — Monteiro (p. 17) described the native method of trapping 

 the manatee near the mouth of the Dande. 



Bengo River: 1897. — Greve (p. 56) states that the manatee occurs in the Bengo, 

 but on whose authority this records rests, I do not know. 



Quanza River: 1875. — In this river, Monteiro (p. 17) saw a canoe with much of 

 the flesh of a manatee in it. As far as I have been able to ascertain, this is the southern- 

 most coastal record of the manatee's occurrence and is probably correctly founded. 



UNCERTAIN OR ERRONEOUS REPORTS OF T. senegalensis 

 The Lake Chad Basin 



1858. — Barth (III, p. 289) wrote that " there is also in the river Shari a very large 

 animal apparently identical with the ayu of the Benue and Niger — Manatus Vogeliir 



1881. — Nachtigal (p. 670), however, saw nothing of the manatee in the Shari 

 region, though he is said to have looked for it. 



1924. — Migeod (pp. 147-167) was unable to confirm the existence of manatees in 

 Lake Chad, even though he made inquiry at several different places. The published 

 records of the Boyd Alexander Expedition, the Mission Tilho, Foureau's Mission 

 Saharienne, and Chevalier's Mission Chari-Tchad do not mention the animal. 



1925, 1928. — The best evidence that the manatee does actually occur in Lake 

 Chad and the Shari appears to be found in certain references which I have not seen 

 personally, but which have been generously transmitted to me by letter from M. 

 Jacques Pellegrin of the Museum National d'Histoire Naturelle. In substance these 

 references (Monod, 1928 and Pecaud, 1925) state that in the Chad basin the manatee 

 is now rare, but as elsewhere, was formerly abundant, that Major General Pecaud has 

 himself seen the skin of a manatee in the region and that he was assured by his aides 

 that previously, perhaps about 1905, the animals were captured near Fort Lamy. 



1866. — In discussing the reputed occurrence of the manatees in the Chad district, 

 Murray (p. 420) states that in his opinion this distribution is quite possible because 

 "the watershed between the Lake and the Sea is not a lofty range of mountains from 

 one side of which the rivers run into Lake Tschad, and from the other into the Niger,
