NOTHOCERCUS.—CRYPTURUS. 453 
Jun. precedenti similis, sed alis crebrius fasciis et maculis ochracescentibus notatis, et pectore fasciis fuscis 
indistinctis ornato, abdomine et tibiis magis distincte fusco fasciatis. (Descr. exempl. forsan junioris ex 
Costa Rica. Mus. nostr.) 
Hab. Costa Rica?48, Cervantes {Zeledon!, v. Frantzius?), Irazu (Rogers*), Faldas 
del Irazu (Zeledon"), Rio Navarro, foot of the Candelaria Mts. (Boucard®), 
Aseni, Achiote de Poas, Estrella de Cartago (Underwood, in litt.); Panama 
(mus. nostr.*), 
Von Frantzius’s Tinamou is allied to V. bonapartii of Venezuela and Colombia; but, 
according to Count Salvadori 4, it may be distinguished by the colour of the greater 
under wing-coverts. In NV. bonapartii these are greyish, barred with dull rufous, 
whereas in V. frantzii they are uniformly greyish-brown, without bars, and the inner 
webs of the primaries are not distinctly rufous, but are greyish, freckled with irregular: 
narrow bars of rufous ¢. 
NV. frantzii was originally described from specimens obtained at Cervantes in Costa 
Rica !, from which country we have received several examples. 
The only note published on the habits of this bird is one by M. Boucard :—* Like 
all the Tinamide, this species is found in the dense parts of the forest, where it feeds 
on insects and seeds. ‘The birds can be easily detected by the noise they make when 
scratching the ground in search of food. They go in pairs, repeatedly calling to one 
another. When fearing danger they run with much rapidity ” & 
Two eggs, attributed to V. frantzii by Mr. Oates 5, are of a darker blue than those 
of any species of Tinamus. 
CRYPTURUS. 
Crypturus, Illiger, Prodr. Mamm., et Av. p. 244 (1811); Salvad. Cat. Birds Brit. Mus. xxvii. 
p. 514 (1895). 
Crypturus agrees with the two preceding genera in its general characteristics, viz. the | 
possession of a hind toe, and ten tail-feathers all hidden by the tail-coverts; but is 
distinguished at once by the smooth hinder aspect of the tarsus. 
The species, as determined by Count Salvadori (J. c.), number twenty-two, of which 
the majority are found in South America. Seven are enumerated in the present work 
as Central American, but some of these are probably not really distinct.
