The exact status of the forms most nearly related to H. palliates 
are, with the scant material available, exceedingly puzzling. It is 
not at all certain that H. galapagensis and H. frazari should be 
referred to that species, as geographic forms, but I have done so for 
the reason that the individual variation in H. frazari is very great, 
tending, on the one hand, to great exaggeration of the originally 
ascribed characters and on the other toward H. palliatus. Whether 
the specimens from Isabella Island and San Mateo, western Mexico, 
should be referred to H. frazari or to H. palhatus, or to either, I can 
not decide; they are so much like the latter in coloration that were 
it not for the question of locality there would be little hesitation in 
referring them to that form. The same applies to the specimens 
from Chile, which, however, certainly are not either H. frazari or 
H. galapagensis. The material examined convinces me of the desira- 
bility of careful investigation of the subject with the aid of more 
abundant material, and also of the probability that several addi- 
tional subspecies of H. pailiatus require recognition.
