from Nicaragua, although in many cases their presence there was to he in- 

 ferred from their known general range. Brief field notes are given by the 

 author, while critical remarks are here and there added by the editor, who is 

 also responsible for the identifications and nomenclature adopted. Mr. Ridg- 

 way's critical remarks include descriptions of four species supposed to be 

 new, as fellows : Oryzoborus nuttingi, Contopus deprcssirostris, Cymbi- 

 lanius lineatus fasctatus, and Porzanu /eueogas/ra, all from Los Sabalos. 

 Geothlypis bat'rdi, also from the same locality, is described as new by 

 Mr. Nutting.— J. A. A. 



Stejneger on the Genus Cepphus.* — This paper consists oi" four parts : 

 'I. Ceppluis motzfeldi (Benickcn)' pp. 210-216; 'IT. On the White-winged 

 Species of the Genus Cepphus (pp. 216-225) ; 'III. Has Ccpfhus carl>o 

 ever been obtained within the fauna) limits of North America?' (pp. 225- 

 227; ; ' IV. Synopsis of the Species of the Genus Cepphus (pp. 227-229). 

 The species recognized are 1. C. mandtii (Licht.) Newt.; 2. C. grylle 

 (Linn.) Flem. ; 3, C. columba Pall.; 4. C. carbo Pall.; 5. C. motzficldi 

 (Bcnick.) Stejn. The status of the last is not considered as satisfactorily 

 settled, but it is thought to be a black-winged Guillemot of the North At- 

 lantic which has been mostly overlooked or regarded as a melanotic phase 

 of the Common Guillemot. The distinguishing characters of C. matidti, 

 as compared with C. grylle, are dwelt upon at length, together with their 

 graphical distribution. The alleged occurrence of C. carbo in North 

 America is discredited. A pretty full citation of the synonymy and biblio- 

 graphical references of the species concludes the paper. — J. A. A. 



Ridgway on New Species of Birds from Cozumel Island, Yucatan. — In 



January, 1SS5. the I'. S. Fish Comniission Steamer 'Albatross' touched 

 at Cozumel Island, and the week spent there wis turned to good account 

 in behalf of ornithology, the opportunity afforded being improved by Mr. 

 }. E. Benedict, Dr. T. II. Bean, and Mr Thomas Lee in forming a large 

 collection of bird skins. Among these Mr. Ridgway has recognized 15 

 species and subspecies new to science. He has promptly published prelim- 

 inary descriptions of them. t and promises a fuller account later. Atabout 

 the same time a collection of Cozumel birds, numbering 27 species, was 

 received by Mr. Salvin. who has given an account of them in the Apri] 

 number of ' The Ibis' (pp. iS^-194, pi. v). It has therefore happened that 

 some of Mr. Ridgway's species were redescribed and renamed by Mr. Sal- 

 vin before Mr. Ridgway's paper reached him. Mr. Ridgway's species, with 

 the corresponding identifications of Mr. Salvin. are as follows: (1) 

 Harperhynckus guttatus (=H. mclauosfoma Salv. sp. n.) ; (2) Trog-
