1 5th of that year. During the first half of the last

14. The stuffed skin and skeleton (14A) of the 

 quagga formerly living in the Berlin Zoological 

 Gardens, are now in the Natural History Museum 

 of that city : and Dr. Mobius kindly informs me 

 that the Berlin collection includes further speci- 

 mens, namely, (15) a quagga skeleton, received in 

 exchange from the Leyden Museum, and (16) a 

 skull obtained by Mr. Krebs, in the Orange River 

 Colony, or near the Liqua ( = Vaal) River. No, 17 

 is a skull also at Berlin, and probably obtained by 

 Krebs in or near the Orange River Colony. The 

 old name of " Liqua "River" being employed to 

 indicate the locality would seem to show that the 

 Berlin specimens were obtained previous to 1844, 

 by which date the term " Vaal River " had come 

 into general use.

 (i8a) at Munich, purchased by Ecklon about 1835.

20. The Senckenbergian Museum at Frankfort- 

 on-Main contains a stuffed quagga, and its cranium 

 (20A) collected in 1831 in South Africa — perhaps 

 by Dr. Smuts, whose dissertation on the Cape 

 mammalia was published a year later.
