PucrasiA NIPALENSIS. 
Forehead, cheeks, chin and lengthened portion of the crest deep 
shining green ; hinder part of the head and the shorter portion of the 
crest buff, with lighter shafts, the two colours blending on the occi- 
put; on each side of the neck an oval spot of white ; feathers of the 
sides and back of the neck and upper part of the back brownish- 
black, with a narrow mark of rich chestnut down the centre, and 
edged with rufous or whitish ; feathers of the lower part of the back 
brownish-black, with white shafts and edges ; wing-coverts brownish- 
black, with white shafts and margins; scapularies broadly margined 
with deep reddish-buff; primaries brown on the internal web, deep 
buff on the outer ; tertiaries pale chestnut, mottled with black along 
the shaft and towards the edge, which is sandy-buff; throat, centre 
of the breast and abdomen rich chestnut; flank-feathers brownish- 
black with white shafts, bordered on each side by a very fine line of 
chestnut, and narrowly edged with grey, the markings becoming 
larger and paler behind the thigh ; under tail-coverts lively chestnut, 
with an oval spot of white at the tip of each ; centre tail-feathers ru- 
fous, stained with black near the shaft, the remainder black on the 
inner web and at the tip, the outer webs chestnut, which colour curves 
round into and occupies a portion of the internal web near the tip ; 
all fringed with white at the tips; bill black; feet horny-brown. 
Total length, 203 inches; wing, 83; tail, 9; tarsi, 23. 
Hab. Nepaul and Bhotan. 
Remark.—In size this bird is the smallest of the three species of 
the genus, but it is by far the most highly coloured and beautifully 
marked; the mantle, the sides of the neck and the flank-feathers 
are conspicuously striated with black, chestnut and grey; the same 
parts in the other species being sombre in comparison. 
Specimens are contained in the collection at the British Museum, 
in that of the East India Company, and, Mr. Gould believes, in that 
of the Jardin des Plantes at Paris. 
2. On THE REPRODUCTION OF THE LOST PART OF AN OPpER- 
CULUM, AND ITS PROBABLE RESTORATION WHEN ENTIRELY 
DESTROYED. By Dr. J. E. Gray, F.R.S., V.P.Z.S. erc. 
It is to be expected that the operculum of a Gasteropodous Mollusk 
may be sometimes broken or injured, but I have never hitherto been 
able to find any very distinct example of the kind, so as to study how 
the repair of the lost part would be effected. That such an occurrence 
would most probably be rare, is easily explained from its situation, 
as the operculum is protected by the last whorl of the spire of the 
shell when the animal is expanded, and by the mouth when it is 
contracted into the cavity of the shell. 
I have lately met with a very distinct example in a specimen of 
Fusus in the British Museum collection. In this specimen the apical 
half of the opereulum has been broken off (see fig. 1), and the lost 
part has been renewed by an irregular roundish process, nearly of
