to another Columbine hybrid, of which two specimens exist in the 

 Collection, the produce of JEctopistes migratorins ^ and Turtur ri- 

 aorius $ . They have neither the tail of Ectopistes nor the collar of 

 risorius, and to any one who was ignorant of their origin, would pre- 

 sent indubitable indications of at least specific distinction. 



And I may also notice in this place a hybrid of an entirely dif- 

 ferent kind, which was deposited during the earUer part of this year 

 in the Society's Menagerie, and has become the property of the Earl 

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

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

 maUa, 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 Tak sire, although I have been altogether unable 

 to trace its actual history.
