Very abimdaut iiutil nearly exterminated by disease in February. 

 The stomachs of several examined were full of small worms. A great 

 many died at Cape St. Lucas and San Jose. I was informed that this 

 mortality occurs every winter. I copy the following from my notes : "Feb- 

 ruary 24. $ P.fuHcm. Back of neck dark brown,* bare skin around eye, 

 brown; base and much of pouch deep red ; specimen in breeding plum- 

 age, and condition.''

* In the single specimen sent the back of the neck is a rich brownish black, quite 

 different from the seal brown or chestnut of all eastern specimens I have seen. Audu- 

 bon describes the color of the naked orbits as pink, the naked skin about base of the 

 bill as deep blue, and the pouch greenish black. Thus it would seem that the soft 

 parts are very differently colored. Should this difterence prove Constant, the west- 

 ern bird would have to be separated as a race. — R. R.
