4. Rheinardius ocellatus nigrescens lintlisdi. 



Rlieinardius ocellatus niyrescens Hotlisch., Hull. II. (I. ('. xii. (March I'.Miti), 

 ]i. r)5 (Ulii Pahang). 



(? ad. Similar to /'//. (in-lln/us orcllntuii, but ditlVrs in several details. The 

 mantle and wings arc conspiennusly darker, brownish lilae.k, with chestnnt-nil'uns 

 mottlings instead of dark brown : the six)ts on the ujiperside are mostly pure white 

 and (|nite round, instead of more or less dark bnlf, and of irregular or elongated 

 shape, as in typi'al T\li. oi-rllntu-f ; the markings on the rnmj) are less numerous, 

 but larger and with more white ; the white spots on the outer secondaries are 

 mostly perfectly round, instead of taking the form of irregular obliijuo lines ; the 

 u])])er crest-feathers are black, not dark brown, the white feathers of the crest 

 apparently more numerous ; the outer wel)s of the enormously elongated reetrices 

 are deejier in colour and more of a blackish brown, and at tlie same time more 

 uniform ; the wide superciliary stri])e is strongly mixed with rufous. The bill is 

 somewhat stouter ; the reetrices of the two males measure only about 66 cm., 

 instead of about 9t) cm. in /?. ocellatus ocellatus, otherwise the dimensions are 

 the same. 



? ad. Somewhat brighter and more rufous than the hens of R. ocellatus 

 ocellatus, but not appreciably dift'erent. The brighter colour may be due to 

 freshness of plumage and skin. 



Two males and one/nwdc were caught by Mr. Waterstradt's native hunters in 

 Ulu Pahang. 



The occurrence oi Rheinardius, hitherto only known from Tonkin, in the Malay 

 Peninsula is a most remarkable fact. 



5. Argusianus argus (L.). 



Pliasianus argus Linn., S'/st. Sat. ed. xii. (ITfUi), p. 2T'J (" Habitat in Tataria 

 (Jhinensi. Pet. C'ollinsou '" — Errore .' I accept Malacca as the tyjiical habitat. 

 Linnaeus' diagnosis is horrid). 



One fei/iiilc sent from the lowland near Mount Tahan, which agrees perfectly 

 with /('/««/('.< from Perak and Tenasserim. 



Argus jiheasants are said to be common at Ulu Pahang, where RlieinanHiis 

 ocellatus iiiyresceiis was obtained : but a box full of ..1 /•//;/.«'«/«/*' skins, all unlabelled, 

 that came with the Jllieinardius, are indistinguishable froiu the Bornean form 

 Aryusianus aryus yrai/i. Therefore they must all have come from Borneo. 



6. Pavo muticus li. 



Piivo muticus Linn., Syst. Nat. ed. xii. (1706) p. 268 (ex Aldrov., Jonst., Brisson. 

 " Habitat in Japonia." — Errore ! I substitute Java as the typical locality). 

 (Common in the lowland districts. 



T. Polyplectron malaccensis (Scoji.). 



P/aisia/ius malaccensis Scop., /'el. Flor. et Fmin. hi.tuhr. jit. ii. p. '.'3 (1786) (ex 

 Sonnerat : Malacca). 



Both se.\es from the Pahang lowlands. 



The name " Polyplectron bicalcaratum " is now usually used for the Malaccan 

 peacock-pheasant, but not correctly. Linnaeus created the name Paro hicalcaratus
