Recently published Ornithological Works. 83 
Joass, and others, he has compiled a list of 84 species of 
birds, with some interesting details. The westward spread of 
the Tree-Sparrow (Passer montanus) is remarkable for its 
rapidity, unless, indeed, the species had previously been over¬ 
looked. It was only in 1882 that Mr. Dalgleish discovered 
its existence on the west coast to the north of the Clyde, and 
now we know that there is a colony on Eigg, while Mr. Dixon 
has obtained it on the remote St. Kilda (cf. Ibis, 1885, p. 82). 
When Mr. R. Gray wrote his f Birds of the West of Scotland/ 
neither the Bullfinch nor the Goldfinch appear to have been 
known as visitors to this or the other islands of the Inner He¬ 
brides. The characteristic bird of Eigg appears to be the 
Manx Shearwater. 
Mr. Evans's second paper is almost sufficiently explained 
by the title. An authentic nest of the Marsh-Tit has not 
been known in the valley of the Forth since 1838. 
10. W. A . Forbes’s Scientific Papers . 
[The Collected Scientific Papers of the late William Alexander Forbes, 
M.A., Fellow of St. John’s College, Cambridge; Lecturer on Comparative 
Anatomy at Charing Cross Hospital; Prosector to the Zoological Society 
of London. Edited by E. E. Beddard, M.A., Prosector to the Zoological 
Society of London. With a Preface by P. L. Sclater, M.A., Ph.D., F.R.S., 
Secretary to the Zoological Society of London.] 
Little introduction will be required by readers of * The 
Ibis' to the present volume, which contains all the published 
writings of our much-lamented associate, including his most 
important work, the Report on the Tubinares collected during 
the voyage of the f Challenger.' Not only the letterpress, but 
also the plates which illustrate his different papers have 
been reproduced, and together form a handsome volume of 
nearly 500 pages and 25 plates. Nearly all Forbes's work 
was done during his tenure of the office of Prosector to the 
Zoological Society of London, a period of only two and a half 
years. The enormous amount of work that he was able to 
accomplish during that short term (which was still further 
reduced by a trip to North America in the summer of 1880 
and by his last journey to Africa, commenced in July 1882)
