Middle of the back (longitudinally), whole rumi), and entire lower parts 

 pale grayish buff, the abdomen and crissum whitish, the jugulum clearer 

 buff, and the rump decidedly " opalescent." Chin and throat dull gray. 

 E"ape crossed by a large crescentic patch of deep golden orange, alto- 

 gether different in color from the jugulum. 



The bill of this raee is so very different in form from that of typical 

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

 almost refer it to another genus. 



The type-specimen is from Ecuador, and was received from Mr. Ber- 

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



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

 cherrima, may be more precisely expressed as follows : 



a. PLTLCHEREiMA. — Nape biiglit straw-yellow, not conspicuously different from the 

 color of the jugulum; throat deep black, abruptly contrasted with the buff of the 

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

 eulmen. . l.VoO. Wing, 2.60-2.75; tail, 1.65-1.80.— jE/«5., New Granada to Eastern 

 Peru.* 



;?. AUREIXUCHA. — Xape deep golden orange, totally different in color from the jugu- 

 lum ; thi-oat dull grayish, not abruptly contrasted with the color of the jugulum. 

 BiU much elongated, measuiing, from the nostril, .43, along the eulmen, .70. Wing, 

 2.55: tail. i.C^.—Hah., Ecuador. 



3.— I'ARUS EUFESCENS, i3. NEGLECTUS. 



Tarns riifc'icrus, 3. ni'tjlechis. Iill>GW. MS. 



Ch. — Similar to typical riifesccns, 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 

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

 may be readily distinguished from more northern examples. The 

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

 Ml-. Henshaw having the past summer obtained it along that stream in 

 Northern Oregon, The specimens which he secured show no ajiproach 

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

 ami^les. 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 irufescens being bright rust-red, or chestnut-rufous, 

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

 bill is also decidedly more slender.
