Phillips on Size Inhe^^itance.

 Philadelphia, xii. 1912, pp. 369-380. 



A Further Study of Size Inheritance in Ducks, with Ohservations on 

 the Sex Eatio of Hybrid Birds. Id. ibid. xvi. 1914, pp. 131-148.] 



These papers contain the results of a series of experiments 

 carried out by the author at the Laboratory of Genetics of 

 the Bussey Institution. 



The birds used were the large white Rouen variety and 

 the smaller domesticated Mallard, which are perfectly fertile 

 with each other, and the object was to find out whether, in 

 the F2 generation, any striking segregation of size occurred. 

 The results did not throw any very clear light on the ques- 

 tion of the Mendelian inheritance of the character of size, 

 and the author suggests that this may be due to " the high 

 coefficient of variability in both the parent races.^' Some 

 other interesting results are recorded. 



Phillips on Birds from the Sudan.

Accompanied by Dr G. M. Allen the writer made an ex- 

 cursion up the Blue Kile from Khartoum in December 1912 

 and January 1913. Their farthest point was Fazogli, a 

 place close to the Abyssinian frontier, -where Mr. Butler 

 found many birds in May, but Mr. Phillips was rather dis- 

 appointed with his booty thence. A list of the species 

 obtained is given, and in it are included two supposed new 

 forms described in the first paper quoted, viz. Caprimidgus 

 eleanoree from Fazogli and Passer domesticus chephreni from 

 Giza, near Cairo.
