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

 length, with copious synonymy, description, and criticism. Finsch recognizes CO. bahamensis, 

 Jlaveola, portoricensis, hartholemiea, luteola, clusiae (v. Wiirt., sp. n.), mexicana, chloropyga, do- 

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

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

 shows the geographical distribution of the species.
