Speciebus prsecedentibus similis, sed fronte et supercilio, facie lateral!, gutture et corpore aubtus mediano albis, 



corporis lateribus vinaceo-brunneis, uigro vermiculatim irroratis, maculis ovatis albis, nigro basaliter

$ E. leyhindi $ similis, sed ubique pallidior et corpore subtus minus distincte nigro fasciato. Long, tota

Hah. Guatemala, San Geronimo, Vera Paz {0. S.^ *, Hague), highlands of Guatemala 



{Bichardson). 



According to Gould ^, the type of E. hypoleucus, procured from Verreaux, was 

 obtained at " Acajutla, Mexico," but probably the locality is erroneous *. So far as 

 we know, this species is confined to Guatemala. The specimen obtained by us at 

 San Geronimo was shot in a field of sugar-cane. 



Nothing has been recorded concerning its habits. 



OETYX. 



Ortyx, Steph. in Shaw's Gen. Zool. xi. p. 376 (1819) ; Grant, Cat. Birds Brit. Mus. xxii. p. 414 



(1893). 

 Colinus, Less. Man. d'Orn. ii. p. 190 (1828) ; Grant, Ibis, 1902, p. 239. 



In the Colins, or " Bob-Whites," the sexes difi'er in plumage, and have no distinct 

 crest. The first primary-quill is intermediate in length between the seventh and 

 eighth ; the tail is rather more than half the length of the wing and is composed of 

 twelve feathers. 



Thirteen species of Ortyx are recognized, of which no less than nine occur within our 

 limits. 0. virginianiis inhabits the Eastern United States, O.floridanus the peninsula 

 of Florida, and 0. cubanensis the Greater Antilles. 0. casfaneus, Gould, is only known 

 from the type in the British Museum ; the locality and other particulars are wanting. 

 It has been suggested that this form may be merely a strongly marked rufous variety 

 of 0. virginianus, and this may eventually prove to be the case. We prefer to retain 

 the name Ortyx for this genus, instead of that of Colinus, which has been recently 

 adopted by American ornithologists f.

• There is no place of this name to be found on the maps of Mexico. Acajutla, however, is a well-known 

 port on the coast of Salvador,
