Jalisco]. 
With apparently only eight specimens of Dactylortyx 
available for comparison Mr. Nelson gives us a revision of 
this genus. He distinguishes three species and one sub- 
species, as follows : — 
Dactylortyx thoracicus (Gambel) . Two females examined^ 
one being Gambel's type* 
Dactylortyx thoracicus lineolatus (Gould). One male 
examined. 
Dactylortyx chiapensis^ sp. n. Four specimens, males and 
females, examined. 
Dactylortyx devius, sp. n. One male examined* 
Along with Mr. Godman, I have again examined tlie 
series of 23 specimens in the British Museum, and, after 
carefully going over Mr. Nelson's work, we can see no reason 
for recognising more than one species. All Mr. Nelson^s 
'^ species " are to be found in the series from Guatemala 
alone. Specimens from Northern Yucatan are somewhat 
smaller and lighter in colour tlian those from other parts of 
Central America, but they do not appear sufficiently different 
to merit a distinct name, and in any case our series, a male 
and two females, is insufficient to decide the question. 
1. Odontophorus guianensis subsp. a. marmoratus (Cat* 
B. xxii. p. 433). 
Odontophorus castiyatus Bangs, Auk, xviii. p. 356 (1901) 
[Chiriqui]. 
Mr. Bangs, in pointing out the distinctive characters 
between his castigatus and 0. marmoratus (Gould), says 
tliat in the latter the top of the head is light chestnut ; but I 
have again examined Gould^s type from Bogota and can 
assure him that this is not the case. The top of the head is 
dark brown ; and our specimens from Chiriqui, though not 
perfectly adult, are undoubtedly of the same species as the 
birds from the United States of Colombia.
