TIIE KERN REDWING 
13 
the area selected for his objective being that lying along the southern side of 
the South Fork of the Kern River, Kern County, California, and also what is 
known as Walker Basin, between the town of Caliente and the above named 
river. 
Although the expedition was delayed in arriving at the main collecting 
ground, and consequently the number and stage of plumage of the individuals 
collected were not up to the desired mark, both are sufficient to make a fail- 
comparison with the nearest forms, the series being composed of twenty adult 
males and eleven females. Three males were kindly loaned me by Dr. Grinnell, 
of the California Museum of Vertebrate Zoology, bringing the number of adult 
males examined to twenty-three. All these specimens tvere taken too late in 
the spring to be in very good plumage, and the wings and tails were sadly 
abraded, while the edging of the feathers was fast being worn away; but the 
measurements of the more permanent parts being the greatest factors in mak- 
ing comparisons in this instance, the condition of the plumage is of minor 
importance. 
Agelaius phoeniceus aciculatus, new subspecies 
Kern Re diving 
Type . — Male adult; no. 7593, collection of J. & J. W. Mailliard; Isabella, Kern 
County, California; May 30, 1914; collected by A. van Rossem. 
Subspecific characters . — Similar to Agelaius phoeniceus neutralis, but of larger 
size, feet averaging somewhat larger; but chiefly characterized by a longer, and com- 
paratively more slender bill 
than any 
other form of 
this genus 
in the United States. 
Cotype . — Female adult; 
no. 7594, 
collection 
of J. 
& J. W. Mailliard; 
Isabella, 
Kern 
County, California; June 1,

Range . — So far this form has only been found in east-central Kern County, Cali- 
fornia, in the Walker Basin, just north of the town of Caliente, and on the South Fork 
of Kern River, between Isabella and Onyx, thus probably being restricted to a very 
small range. 
Remarks . — The length of a skin is not of much value unless specimens are 
so prepared as to approximate fairly closely the original flesh length, or unless 
this measurement is used only in comparing a number of skins put up by the 
same person. In this particular instance 31 skins of male A. p. neutralis were 
compared with 20 skins of A. p. aciculatus. and the result showed an average 
length of 211 mm. for the former and 221 mm. for aciculatus, with a similarly 
proportionate difference among a number of females compared under like con- 
ditions. These measurements approximate those of A. p. fortis , which is sup- 
posed to be the largest form of Agelaius.
