As will be seen from this table of measurements, the Orinoco specimens 

 marked "cJc?" are rather larger than an adnlt /mafe from Yquitos (Upper 

 Amazons). Perhaps the difference is only a se.xual one. Specimens from (Jayenne 

 should be compared.

This ? is much smaller than (Jherrie's bird No. 10314, marked ?, which nearly 

 agrees in size with the birds Nos. 10624, 10625, marked SS. This No. 10314 is 

 probably a <^, though there are veri/ seldom errors in sex on Mr. Cherrie's labels.

This specimen agrees with two others from British Guiana (H. Whitely coll.), 

 and one from Bahia (trade-skin) in Mns. Triug, except that the edges of all the 

 feathers of the upper surface are olivaceous grey instead of olive-brown. 



* Mr. Andr6, in his work on the Caura River, chapter iii., p. 16, says: "Near the mouth of the 

 Mate River, ou a large sandbank, 1 witnessed an extraordinary spectacle. For over a mile in the water 

 on each side of this stretch of sand, and sitting on it, were myriads of this Cormorant, called " cotua " by 

 tlie natives. 1 had seen immense docks at t'umaua, for it is plentiful ou the north coast of Venezuela, 

 but never before had 1 beheld such a mult tude of birds assembled in one spot."
