28 BOURNS AND WORCESTER: PRELIMINARY NOTES, 



pine representatives of the genus. R. albigulari s is a deep woods 

 form and is extremely rare in the localities visited by us.

 brighter on the rump. Tail dark chestnut, much brighter on outer

 when shot. 



Feeling an especial interest in the Zoo- geographical problems

 tribution within the group of the resident land birds we worked out 

 as carefully as possible the distribution of all the species of birds 

 and mammals met with. Following is a list of the species for which 

 new localities were determined. As has already been stated, Mr. A.

 island. Species found thereby him as well as ourselves are marked 

 with a star placed after the name of the island. We found Dr. Platen
