73. Salvadori on Trerolsema leclanclieri^ Bp. 
[Intorno alia Trerolcema leclancheriy Bp., Nota. Atti R. Ac. Sci. Tor. 
xiii. pp. 425-428.] 
Having examined the type of Trerolcema leclancherij Bp. 
(Mus. Paris), said to be from New Guinea, Salvadori pro¬ 
claims its identity with Leucotreron gironieri of the Philip¬ 
pines. Mr. Elhot (P. Z S. 1878, p. 568) has come to the 
same conclusion. 
74. Salvadori on a new Hermotimia. 
[Intorno agl’ individui del genere Hermotimia dell’ Isola del Duca di 
York. Atti R. Ac. Sci. Tor. xiii. p. 530.] 
Cinnyris aspasia (Less.) of Shelley and Sclater, from Duke- 
of-York Island, is separated as Hermotimia corinna. In our 
opinion Dr. Salvadori goes rather too far in making so many 
different species of this form of Sun-bird. 
75. Salvadori on new Species o/Calornis and Carpophaga. 
[Due nuove specie di uccelli dei generi Calornis e Carpophaga della sotto- 
regione Papuana. Atti R. Ac. Sci. Tor. xiii. p. 535.] 
Calornis, sp. inc., of Sclater (P. Z. S. 1877, p. 554), from 
the Admiralty Islands, is characterized as C. purpureiceps, 
and Carpophaga rufigula is described (being the representative 
in the Solomon Islands (San Cristoval) of C. ruhracera of 
New Ireland) from a specimen in the British Museum, ob¬ 
tained by MacGillivray. 
76. Wallace's ^ Tropical Nature.^ 
[Tropical Nature, and other Essays. By Alfred R. Wallace. 8vo, 
pp. 356. London: 1878. Macmillan & Co.] 
Mr. Wallace's essays on tropical nature, with which his 
twelve years^ experience of the eastern and western equatorial 
zones have rendered him so familiar, will be read with great 
interest by every naturalist. The opening chapter is worthy 
of special notice, as giving an explanation of the causes of 
the wonderful uniformity of the climate of the tropics in 
popular language, and in a manner we have not seen suc¬ 
cessfully accomplished elsewhere. Hardly of less importance 
are the second and third essays on the peculiarities of the
