ZOOLOGICAL LITERATURE. 
PICARIiE. 
On the respective Affinities and Classification of the Non-passerine Inses-- 
sores. E. Blyth, Ibis, 1864, pp. 411, 412, 
PiCIDiE. 
Celeus fraseri appears undistinguishable from C. mentalis, P. L. Sclater 
and 0. Salvin, P. Z. S. 1864, p. 367. 
Qecims tancola and Ficus insularis are figured. J. Gould, B. As. part xvi. 
TROGONIDiE. 
Trogon cmdnnus of Mr. Lawrence (Ann. Lyc. N. York, vii. p. 463), the 
type of which is evidently taken from a young bird, is attributed to T. caligatus, 
P. L. Sclater and O. Salvin, P. Z. S. 1864, p. 364. 
BuCCONIDiE. 
Megalcema michalis is figured. J. Gould, B. As. part xvi. 
Bucco leucocrissus, from Ecuador, is hardly separable from B. dgsoni, from 
Guatemala. P. S. Sclater and 0. Salvin, P. Z. S. 1864, p. 363. 
Malacoptila panamensis and M. inornata may probably be sexual forms of 
the same bird. P. L. Sclater and O. Salvin, P. Z. S. 1864, p. 363. 
MoMOTIDiE. 
All the so-called species allied to Momotus lessoni, especially M. psaluirus, 
M. microstephanus, and M. suhrufescens, require a careful examination, which 
will probably lead to the union of several obscure forms which are barely 
recognizable. P. L. Sclater and 0. Salvin, P. Z. S. 1864, p. 362. 
Momotus martii is referred to M. semirufus. P. L. Sclater and O. Salvin, 
P. Z. S. 1864, p. 363. 
Alcedinid^. 
Alcedo ispida is figured. J. Gould, B. Grt. Br. part vi. 
CaPITONIDtE. 
The error of uniting the Capitouidce with the Bucconidce is again combated 
by E. Blyth, Ibis, 1864, p. 411. 
Tetragonops frantzii is a new species from Costa Bica, smaller and quite 
differently coloured from T. rhamphastinus. P. L. Sclater, Ibis, 1864, pp. 371, 
372, pi. X. 
Monasa Jlavirostris of Strickland (Contr. Orn. 1850, p. 47) had been already 
described from the same specimen by Lafresnaye (R. Z. 1860, p. 216) as M. 
axillaris. J. Cassin, Proc. Acad. Philad. 1864, p. 288. 
Capita versicolor (Muller). A specimen of this species, which is little known 
to modern ornithologists, but identical yffiih. ' Bucco pictus of Boddaert, B. ele- 
gans of Gmelin, and B. maynanensis of Brisson, and figured by Buffbn, PI. Enl. 
330, is in the Museum at Philadelphia. J. Cassin, Proc. Acad. Philad. 1864, 
p. 288. ■ .
