Tetrao obscurus ; I am almost inclined to believe it differs from that 

 species. 



(I must see males of this species before I can consider it different 

 from T. obscurus. — P. L. S.) 



3. Callipepla picta (Douglas). 



Found in flocks in the Sierra Nevada near Shasta. 



4. Dryocopus pileatus (Linn.). 



I have only seen this fine species of Woodpecker in the Pine 

 Forests of the Sierra Nevada, at an elevation of 4000 feet, and there 

 it is somewhat rare, and difficult to capture. The present specimens 

 were taken on Scott's Mountains, Trinity County, in October. 



5. Melanerpes torquatus (Wils.), ? juv. 



This bird I first saw in Scott's Valley, on the Pinus Benthamiana. 

 Like the Melanerpes formicivorus they live in small communities, as 

 I saw three pairs together in the above locality. In winter they mi- 

 grate towards the oak-groves at the base of the Sierra Nevada, seek- 

 ing a milder climate than the snow-covered pine regions. 



6. Melanerpes rubrigularis, Sclater, sp. nov. (PI. CXXXI.) 

 Supra nitenti-niger ; linea circumnuchali ab oculis incipiente, 



altera utrinque suboculari a rictu latiore, tectricibus alarum 

 superioribus, dorso postico ei caudce tectricibus superioribus, 

 necnon maculis secundariarum trium extimarum apicalibus et 

 in />offonio externa primariarum tertice, quartet et quintce albis: 

 subtus nitenti-niger, gula media ruberrima, abdomine medio 

 flavicante, lateribus et crisso albo nigroque variegatis ; tectri- 

 cibus alarum inferioribus et remigum pogonio interior e cineras- 

 centi-nigris, maculis quadraiis numerosis albis : caudce rectri- 

 cibus omnino nigris : rostro et pedibus nigris. 

 Long, tota 8'5, alse 5*4, caudee 3"5, rostri a fronte 1*0, tarsi 0'8. 

 (This Woodpecker, which is represented by Mr. Bridges as very 

 rare, appears to have escaped the researches of the American natu- 

 ralists ; at least I am acquainted with no record of its existence, 

 though it may have been described quite lately. It appears to be 

 well placed in the genus Melanerpes, of which no less than six species 

 are already known to inhabit California, namely M. erythrocephalus, 

 M. torquatus, M. thyroideus (Cassin, B. Cal. pi. 32 : Picus natalice, 

 Malherbe, Cab. Journ. f. Orn., 1854, p. 271), M. formicivorus 

 (Cassin, B. Cal. pi. 2), M. albolarvatus, and M. ruber. From all 

 these it is quite different in colouring, and may be recognized at 

 once by its black breast and bright scarlet throat-mark, whence I 

 have named it M. rubrigularis. — P. L. S.) 



A very rare bird, the only one of the species I have ever seen. 

 Shot in Trinity Valley, on the pines. Probably this may occur more 

 frequently in Oregon or the British possessions. Had it been com- 

 mon, I should have seen it in the southern part of the State of 

 California.
