 monograph. 



Hierophasis dissimilis. A New Mutation Form of H. swinhoii Gould. By 

 A. Ghigi. — Contains much interesting information on the pedigree of these 

 pheasants bred in captivity through several generations. The advisability 

 of naming such forms as this is however decidedly open to question.

Kellogg, V. L. A Fourth Mallophagan Species from the Hoatzin. 

 (Science, March 5, 1915.) — The nearest- allies of three of these parasites 

 of the Hoatzin are found on shore birds and storks, while species congeneric 

 with the fourth occur on pheasants. The data do not throw much light 

 upon the relationship of the Hoatzin but suggest an affinity with water 

 birds rather than with the gallinaceous group. 



Swarth, H. S. Albinism in the English Sparrow (Science April 16, 

 1915). — To the notes on albinism in the English Sparrow, a well known 

 condition that seems to have been just discovered by certain contributors to 

 ' Science,' Mr. Swarth adds some really valuable data. He calls attention 

 to the adaptation of Brewer's Blackbird (Euphagus cyanocephalus) to 

 altered conditions brought about by increased settlement in southern 

 California, and to the prevalence of albinism in this species. The House 

 Finch (Carpodacus mexicanus frontalis) however, which is still more "do- 

 mesticated " does not exhibit such a tendency.

Dewar, J. M. The Sense of Direction. (Zoologist, February 15, 1915.) 

 — The two theories (1) knowledge of landmarks, (2) sensing position "in 

 terms of bodily displacements in space experienced on the outward jour- 

 ney " are outlined. A number of observations are given which show that 

 the latter is a more satisfactory hypothesis than the former.
