Mallophaga from Californian Birds. 
By V. L. Ketioce and J. H. Patne, Stanford University, 
California. 
The following determinations of Mallophaga and records 
of hosts are based on specimens taken from various birds at 
Monterey, California, by Mr. Jos. Clemans, Chaplain of the 
15th Infantry Regiment, stationed at the Presidio. 
Docophorus pertusus Nitzsch, var. monachus n. var. 
One male from the Virginia rail, Rallus virginianus (Mon- 
terey, California). 
The type, D. pertusus, has been 
found on the following birds in Cali- 
fornia: Fulica americana, Erismatura 
rubida, and Colymbus nigricollis cali- 
fornicus. The sinuous posterior mar- 
gin of the first abdominal segment 
shown in the figure of the variety is 
~ oy also found in the type, though it has 
. not been referred to heretofore. 
The variety differs in the greater 
number of hairs found on the clypeus 
and on the abdomen. On the clypeus 
of the type there are two small hairs 
near the trabeculae while in the vari- 
ety there are about eight on each side 
extending from the trabeculae to the 
expansion of the pincer-like organs.
