This is a very complete aud workmanlike monograph, in which, after general considerations 

 and an account of the genus, the ten species recognized by the author are treated at full 

 length, with copious synonj-my, description, and criticism. Finsch recognizes CG. bahamensis, 

 flaveola, portoricensis, bartholemica, luteola, clusiae (v. Wurt.. sp. n.), mexicana, chloropyga, do- 

 minicana, martinicana, as valid, with 0. minor Bp., Muscicapa melanoxantha Sparnn., and 

 Certhia trochlea Sj)arnn., as dubious, and adds a note on Certhiola caboti Bd. MS. A map 

 shows the geographical distribution of the species.
