There may be still, no doubt, a few forms left iu the recesses 

 of Peru and Ecuador, but we suspect that the additions yet 

 to be made will not be very numerous. 



Two new genera are proposed by Count v. Berlopsch in 

 the present memoir — Chrysothlypis for Tachyphonus chry- 

 somelas, and Erythrothlypis for Dacnis salmoni. 



One new species is described, namely Chlorospingus 

 hondurasianus, and 17 new subspecies, or " conspecies,'' as 

 Count V. Berlepsch prefers to call them, namely : — 



1 . Euphonia aurea pileata. 



!?. riificeps exsul. 



3. violacea mayna. 



4. Calospiza larvata centralis. 



5. Iridosomis Jelskii holiviana. 



6. Poccilothraiipis lunulata inter- 



cedens. 



7. palpebrosa oli- 



9. Coinpsocoma sinnptitosa (viti- 

 orpdce. 



10. Lanio versicolor parvus. 



11. Hemithraupis Jfavicollis ttell- 



7nayri. 

 1'2. Xemosia pileata 7)ana. 

 13. Hemispingus atripileus chlori- 



ffasfer. 



vnceiceps. 14. Baarremoyi torquatus jthyyus, 



8. palpebrosa 



cariilescens. 



15. Psittospiza riefferi holiviana. 



16. Saltator similis ochraceiventris. 



17. grandis yucatanicus. 



After a preface, in which many difficult questions relating 

 to the Tanagers are discussed, our author proceeds to the 

 systematic arrangement. He places the curious form 

 Procnias at the head of the group, but ranks it as a separate 

 Family "' Procniatidce." If this bird really nests iu hollow 

 trees and lays white eggs, it can hardly be associated very 

 closely with the Tanagers. 



The systematic list of Tanagers begins with the Eu- 

 phoniiupe and ends with the thick-billed Pityliuae. j\[r. 

 Ridgway has proposed to transfer the latter group to the 

 Fringillidae, but Graf v. Berlepsch does not ayree to this 

 view. Xo descriptions are given, though the localities of every 

 species and subspecies are carefully worked out. In spite 

 of this omission, which is much to be deplored, we look 

 upon this essay as a most useful piece of work which the 

 authors of the proposed history of South American Birds 

 will do well to study carefully. It is based primarily on the 

 collection at Schloss Berlepsch which, as the owner informs
