20. Ridgway on the Birds of North and Middle America. 



[The Birds of North and Middle America. By Robert Ridgway- 

 Bull.U.S.Nat. Mus. No.oO. Fart IV. Washington, 1907. 8vo. 973 pp.] 



The fourth volume of Mr. Ridgway's great work on the 

 hirds of North and Middle America was received in this 

 countrv in September last. It continues the history of the 

 Passerine Birds to the end of the Cotingidse, comprising the 

 ten families Turdidse, Zelodoniidse, Mimidse, Sturnidae, 

 Ploceidse, Alaudidse, Oxyrhynchidse, Tyrannidse, Pipridae, 

 and Cotingidse. Of these the Sturnidre and Ploceidse might 

 have been omitted, as they are both purely Palseogean 

 types, represented in America in one case only by the 

 Common Starling [Sturnus vulgaris), which is an occasional 

 straggler to Greenland, and in the other by two Weaver- 

 birds [Spermestes cucuUata and Estrilda melpoda), which 

 have been introduced into Porto Uico. There remain eight 

 families, six of which are purely Neogean, while two, the 

 Turdidai and Alaudidse, are also met with in the Old World. 



Of the family Turdidse 96 species and subspecies are 

 recognised, the only species left in the genus Turdus being 

 Tardus iliactis, which is an occasional visitor to Greenland : 

 all the remaining typical Thrushes are transferred to the 

 genus Planesticus. In spite of Sclater's protests (see ' Ibis,' 

 1903, p. 142), the na.me Txorevs of Bonaparte is still retained 

 for Turdus mevius, whereas Bonaparte states that the bird 

 to which he applied that term (sc. Taenioptera rufiventris) 

 '^n'est pas une Grive ni meme un Chanteur, mais un 

 Yolucre Tteniopterien." 



Next to the Thrushes come the Mocking-birds (Mimidae), 

 of which the Author recognises 61 species and subspecies. 

 Following Mr. Lucas he considers this group to be distinct 

 both from the Wrens (Troglodytidae) and the Thrushes 

 (Turdidse), with one or other of which they have been
