Mallophaga. 
Menoponidae. 
2. Menopon sp. 
A single female said to have been taken from Spheniscus magellanicus 
Forst. which is undoubtedly an error. It is definitely one of the larger Meno- 
ponidae and the correct host is probably either an Albatross or a Petrel. 
3. Colpocephalum sp. 
A single female from Cerchneis sparverius fernandensis Chap., Masatierra, 
25s Ol:

Several females and males from Pelecanus occidentalis thagus Molina, Chile, 
Coronel, 14. VII. 1917. 
The original description of this species was from Pelecanus sp. (Chile) but 
as FERRIS has suggested the type host may be taken to be Pelecanus occiden- 
talis thagus Molina. The specimens at hand agree very well with FERRIS’ 
redescription and figures.|

A few specimens of this interesting species were accompanied by quite 
incorrect host data in the collection. Owing to the distinctive character of the 
species I have no hesitation in stating that they were quite definitely obtained 
from Spheniscus magellanicus Forst., specimens of which were collected by the 
expedition at Santa Clara & Masatierra.
