a pair nested up a donga on the north bank, because they 

 were there all the summer and used to swim about at the 

 mouth of it in the evening. The Black Duck may often 

 be seen flying about in the middle of the day.

 edge of the large dam on the 20th of May.

A flock of Red-billed Teal used to feed on a sandbank in 

 the river every night, leaving soon after dawn.

I occasionally saw one or two Ostriches on the north bank 

 of the river. All were probably escaped birds. 



XXI. — Remarks on the Type-specimens of certain Birds named 

 by the late Carl Peter Thunberg. By Dr. Einar Lonnberg, 

 C.M.Z.S. 



In the Zoological Museum of the lioyal University of Upsala 

 there still exist certain specimens of birds which were named 

 and described by Carl Peter Thunberg. I have recently 

 examined these types, which are the more important as 

 Thunberg's names have been almost entirely unknown to and 

 disregarded by later authors, even in such an important work 

 as the i Catalogue of Birds in the British Museum.' Thun- 

 berg was not an ornithologist ex professo, and in his various 

 papers he sometimes erred in naming, and describing as 

 new, birds which were already known and described, in certain 

 cases even by Linnaeus. In some instances, nevertheless, 

 Thunberg's names have priority, and must have their rights, 

 after the descriptions have been compared with the still 

 existing and labelled type-specimens, which have been 

 examined and determined.
