 Collection, the produce of Ectopistes migratorius J* and Turtur ri-

 of Derby. The pencil of Mr. Wolf has again afforded me the means 

 of recording the characteristic features of this singular Bovine (Mam- 

 malia, PI. XV.) ; and it is only necessary for me to add to the in- 

 formation conveyed by his figure, that this animal was imported 

 from India some four years ago, and appears to be the produce of a 

 Zebu mother and a Yak sire, although I have been altogether unable 

 to trace its actual history.
