Speciebus precedentibus similis, sed fronte et supercilio, facie laterali, gutture et corpore subtus mediano albis, 
corporis lateribus vinaceo-brunneis, nigro vermiculatim irroratis, maculis ovatis albis, nigro basaliter 
fasciatis, conspicue ocellatis distinguendus. Long. tota circa 7°5, ala 4°2, caude 2:2, culm. 0-5, tarsi 1:0. 
2 #. leylundi Q similis, sed ubique pallidior et corpore subtus minus distincte nigro fasciato. Long. tota 
circa 7-5, ale 4-0. (Descr. maris et femine ex San Gerénimo. Mus. nostr.) 
Hab. Guatemata, San Gerénimo, Vera Paz (0. 8.24, Hague), highlands of Guatemala 
(Richardson). 
According to Gould}, the type of ZH. 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 Gerdnimo was shot in a field of sugar-cane. 
Nothing has been recorded concerning its habits. 
ORTYX. 
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 differ 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. O. virginianus inhabits the Eastern United States, O. foridanus the peninsula 
of Florida, and O. cubanensis the Greater Antilles. 0. castaneus, 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 O. virgintanus, and this may eventually prove to be the case. We prefer to retain 
the name Ortyz 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.
