 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 thoracicns (Gambel) . Two females examined, 

 one being Gambel's type* 



Dactylortyx thoracicns 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 the 

 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 than 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 castiyutus Bangs, Auk, xviii. p. 358 (1901) 

 [Chiriqui j . 



Mr. Bangs, in pointing out the distinctive characters 

 between his castigatus and 0. marmoratus (Gould), says 

 that in the latter the top of the head is light chestnut ; but I 

 have again examined GoukFs 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.
