On the natural and artificial Fecundation of JE^iloips hy Triticum. 

 By M. GoDRON. 



The author referred to the researches of M. Fabre upon Mgilo'ps 

 triticoides^ from which it appears that this grass is produced from 

 seeds ofjEgilops ovata, and that by cultivation it gradually approaches 

 cultivated wheat. He does not, however, by any means admit the 

 conclusion deduced from this fact by M. Duval, namely that wheat 

 has originated from the ^. ovata, and is nothing but a metamor- 

 phosis of the latter plant. 



M. Godron, by examining the circumstances under which the ^. 

 triticoides is met with, has arrived at the conclusion that this plant 

 is only an accidental product ; it is never seen except on the edges 

 of wheat-fields or in their neighbourhood ; its habit resembles that 

 of the varieties of wheat near which it has grown ; it possesses beards 

 when growing in the neighbourhood of bearded wheat, but these are 

 rudimentary in places where beardless wheat is cultivated, and it is 

 less fertile than legitimate species. He considers that jE. triticoides 

 exhibits all the characters of a hybrid plant, and that it is the product 

 of the fecundation of JE. ovata by cultivated wheat. 



He has, moreover, confirmed this view by direct experiment ; the 

 artificial fecundation of jE. ovata by Triticum vulgare has given him 

 the two varieties of ^. triticoides which are met with in the South 

 of France. He has also obtained two new hybrid plants, — one by 

 the fecundation of JE. ovata by Triticum spelt a, the other by the 

 action of the pollen of T?'iticum durum upon ^gilops triaristata. —

 ' • THE OUNCES. 



The Ounces, or Tortoise-shell Tigers as they have been called, 

 should form a particular group of Cats, to which the name of Uncia 

 may be attached. They are easily characterized by the great length 

 and thickness of their cylindrical or rather clavate tail, and the 

 marbling of the colours on the fur. They are confined to Asia.

THE AFRICAN SEAL, HELIOPHOCA ATLANTICA. 



I have just received a well-preserved skin and the skeleton of this 

 Seal from Algeria, under the name of Phoca lejporina. It certainly 

 cannot be the Phoca leporina of Lepechin, in Act. Acad. Petrop.
