The object of this paper is to exhibit the number of ‘species 
known and to indicate their geographical distribution ; but it is 
not so clearly arranged as most of the author^s writings, and we 
are not sure that we entirely understand his views. It would 
appear that thirteen species are discriminated by him, of which 
three seem to be described as new, while one, C. nidifica, is 
separable into seven varieties or local races. Mr. Gray abstains 
from employing the specific name esculenta” as he considers 
its typical representative to be still enveloped in much doubt. 
Collocalia hypoleuca^ C. spilura, and C. ncylectn are separated from the 
C. cscnlmta of Mr. Wallace (P. Z. 8. 1803, p. 384). The first was long ago 
described (P. Z. S. 1858, p. 170). The second is from Batchian, and has the 
spot on the first and fourth rectrices not so prominent ns on the second and 
third } it is sometimes hardly visible on the first. The third is from Timor j 
in its upper surface it is totally different from those of the other localities, 
and it is of a more pure white beneath. G. R. Gray, ut suprit, pp. 120, l21. 
Collocalia uropyyialis from Aneiteum is separated from C. leucopyyia of 
Wallace (/oc. a^.) from New Caledonia. It has the abdomen pure white, 
and shorter wings. — Collocalia hrevirostrisy C. gelatinosa, C. malaisia, C, phi^ 
lippina, and C, ualensis, as well as forms from Celebes,, the Moluccas, Papua, 
Timor, and Marianne Islands, are all referred to local races of C. nidifica,

TROCHILIDAi:.

An addition to the paper we noticed last year (Zool. Recojd, ii. p. 100), 
Some of the Trochilidce have a double moult j and this fact accounts for 
doubts hitherto existing as to the identification of Azara’s species.

The object of this work is to supply the want of an analytical 
arrangement of this family, and to assign characters to the dif- 
ferent groups composing it. Prof Mulsant starts by dividing 
the Trochilidai into two tribes, Trochiliens and Ornis- 
miens,'’^ distinguished by characters drawn from what he calls 
the mandibule — the maxilla of almost all other ornitho- 
logists, for he transposes this term and mandibula. Of the 
Trochiliens he makes two sections, left unnamod ; the first
