Middle of the back (longitudmally), whole rmnp, and entire lower parts 

 jiale grajish buif, the abdomen and crissnui whitish, the jngulnm clearer 

 bnff, and the rumj) decidedly " opalescent." Chin and throat dull gray. 

 Xape crossed by a large crescentic patch of deep golden orange, alto- 

 gether different in color from the jugulum. 



The bill of this race is so very dilferent in form from that of typical 

 D. pulclierrima, and more especially from that of the other Dacni, as to 

 almost refer it to another genus. 



The type-si>ecimen is from Ecuador, and was received from Mr. Ber- 

 nardo Thiel, through my friend Mr. Jose 0. Zeledon, of Costa Eica. 



The differences between this species and its nearest relative, D. ijul- 

 cherrima, may be more precisely expressed as follows : 



a. PULCHERRIMA. — Nape bright straw-yeUow, not conspicuously different from the 

 color of the jugnlnm; throat deep black, abruptly contrasted Avith the buff of the 

 jugulum. Bill moderately elongated, measuring, from the nostril, .30-.37, along the 

 culmeu, .45-50, Wing, 2.60-2.75; tail, 1.65-1.80.— jffa&., New Granada to Eastern 

 Peru.* 



;9. AUREiNUCHA. — Nape deep golden orange, totally different in color from the jugu- 

 lum; throat dull grayish, not abruptly contrasted with the color of the jugulum. 

 Bill much elongated, measuring, from the nostril, .43, along the culmen, .70. Wing, 

 2.55; tail, 1.60. — Hal)., Ecuador. 



3.— PAEUS RUFESCENS, /?. NEGLECTUS. 



Parns riifcscens, (3. negJectus, Ridgw. MS. 



Ch. — Similar to typical mfesceiis, but sides grayish, only slightly 

 tinged with rusty, instead of wholly bright chestnut-rufous, or rust-red. 



Hab. — Coast of California. 



All of the many Californian specimens of this species which have 

 come under my notice agree in the above characters, by which they 

 may be readily distinguished from more northern exami^les. The 

 typical race extends at least as far south as the Columbia Eiver, 

 3Ir. Henshaw having the past summer obtained it along that stream in 

 Northern Oregon. The specimens which he secured show no approach 

 to the Californian form, being quite indistinguishable from Sitkan ex- 

 amples. So far as I have been able to discover, the difference, so far as 

 coloration is concerned, consists solely in that indicated above — the 

 entire sides in true rufesccns being bright rust-red, or chestnut-rufous, 

 quite as uniform and continuous as that of the back, but lighter. The 

 bill is also decidedly more slender. 



* Five sx^ecimens measured. The principal synonymy of the typical race is as follows :
