Mr. Salvin’s second paper is a careful examination of tlie new species 
of Petrels obtained by Dr. H. H. Giglioli during the voyage of the Italian 
corvette “ Magenta ” round the world, and described in the “ Ibis ” in 
1869. Mr. Salvin examined the type specimens, and accompanies his 
review with fine illustrations drawn by the w^ell-known bird-painter, 
Keulemans. These species, according to Mr. Salvin, should all stand as 
good and novel species. Their names are as follows : CEstrelata magentce, 
CE. armingoniana, (E. trinitatis, CE. dejilippiana, aiid Puffinus elegans. —

Catalogue of the Birds of the Islands of Malta and Gozo. — 
The Boston Public Library has recently received a copy of Mr. Grant’s 
catalogue of Birds found on the islands of Malta and Gozo. Naturally, 
a list of the birds occurring in these islands, situated midway between the 
northern coast of Africa and the southern shores of Europe, divides into 
three principal groups : migratory birds, properly European ; visitants, 
from Africa ; and resident species. Besides these, not always distinguish- 
able, are purely accidental or chance callers. Among the most noticeable 
of this small group it is interesting to note such purely American species 
as Tringoides macularius, Actiturus hartramius, and Lams atricilla. Tryn- 
gites rufescens, American, but not uncommon in Europe, has also been 
found there. We also notice the occurrence in these islands of birds that 
are somewhat cosmopolitan as well as North American, such as Eissa tri- 
dactyla, Lams marimis, Plectrophanes nivalis, Tringa canutus, T. maritima, 
T. subarquata, T maculata, Strepsilas interpres, Anous stolida, and several 
species of Ducks, common to both continents. — T. M. B. 
Eidgway’s “Studies of the American Ealconid^.” — During the 
last two years Mr. Eobert Eidgway has given ns, in a series of special 
papers, some of the results of his protracted investigation of the American 
Falconidce. In June, 1875, appeared his Outlines of a Natural Arrange- 
ment of the Falconidce,” based on an extended examination of the oste- 
ology of the leading types of raptorial birds. In this paper he indorses 
most fully the classification of the Birds of Prey proposed in 1867 by 
Professor Huxley, which unites the Old-World Yultnres {Vidturidce of 
most authors) with the Falconidce, separates the Secretary Bird as an inde- 
pendent iami\j {Serpentariidce), and makes the Vultures of the New World 
a family {Gartliartidce) distinct from the other Diurnal Birds of Prey. 
Mr. Eidgway recognizes among the Falconidce only two subfamilies,. — 
namely, Falconince and Buteonince, — thereby differing very widely from 
most previous writers, some of whose classifications he rather sharply 
criticises. ,The subfamily Falconince he arranges in four minor divisions 
or “ groups,” under the names Falcones, Polybori, Micrastures^ and Herpeto-
