conforms in general character with its predecessors. The families and 

 genera, as well as the species, comprise in a number of instances several 

 groups that are usually accorded, respectively, independent rank. All 

 the true thrushes, for example, are referred to Turdus, and all the true 

 wrens to Troglodytes. 



In respect to matters of nomenclature, the name Prunella properly 

 displaces Accentor, and the name of the family becomes Prunelhdse. 

 Chelidon Forster replaces (and we fear with good reason) Hirundo for the 

 H. rustica group, and Hirundo is again assigned to the House-Swallow or 

 the urbica group. Among the new subspecies we note an Irish race of the 

 Dipper {Cinclus cinclus hibernicus), based on specimens from County 

 Cork, Ireland. The British Islands now have two insular races of the 

 Cinclus cinclus group, the other being C. c. britannicus Tschusi. — J. A. A. 



Ogilvie-Grant's 'A List of British Birds.' — This list is in tabular form 

 and is admirably arranged to show concisely and at a glance the status 

 of each species as a bird of Great Britain: as to whether it is (1) resident 

 and breeds, (2) a regular summer \'isitor that breeds, (3) a regular autumn, 

 winter or spring visitor that does not breed, (4) an occasional \'isitor that 

 formerly bred, or (5) an occasional visitor never known to breed. "When 

 species have not occurred more than six times references are given to the 

 works in which they have been recorded." Species of doubtful record and 

 species artificially introduced are entered in the list in brackets and are 

 not numbered. The species known as British birds number 442. The 

 list is printed with one side of the leaf blank, so that it can be cut up for 

 labelling. The nomenclature is binomial, even in the case of local sub- 

 species; in each such instance, however, the name is followed by the 

 statement, in a separate line, "A sub-species of" (whatever the species may 

 be), or by formula? like this: "Parus ater, Linn." followed by, in a separate 

 line, "The Continental form," and "Parus britannicu.s, Sharpe and 

 Dresser," followed by, in a separate line: "British sub-species of P. ater." 

 This may be soothing to the feelings of those who dislike trinomials; but 

 the general disregard of all modern codes of nomenclature, incidentally, 

 throughout the list will not be soothing to those who have regard for 

 correct nomenclature. The desirability thus recognized of explaining the 

 relative status of forms here designated by binomials is an admission 

 of the utility in such cases of the trinomial method. — J. A. A.
