INTRODUCTION. 
While examining the recent oe in the rich collec- 
tions of the Zoological Survey in order to compare them with 
the-fossil species in the collections of = Geological Survey 
a specimen labelled 
**Luponia Broderipii ” It ha sas been possible to 
trace the history of this specimen, the locality of which is 
given as “ Mauritius.’ Cyprea Broderipwi, a species known 
only from Madagascar, is a shell of the greatest easily and 
value. In 1888, when Melvill published his monograph on the 
genus Cypre a (M emoirs and Proceedings of the Manchester 
Literary and “Philosophical Society, 4th series, Vol. I. pp. 184— 
252), only six specimens were known in the world’s collections, 
| no further addition to that number appears to have been 
ecorded since that date. It is unfortunately tale that the 
Calentta specimen has been misinterprete e dorsal aspect 
of the specimen under prtaiesene clearly cart the buff 
available illustrations of Cyprea nivosa, while Cyprea Broder- 
ipit is distinguis y a relatively wider aperture and more 
elongate denticulations. Moreover, as already mentioned, the 
specimen under consideration is said to be “from Mauritius, 
hitherto the only recorded habitat of Cyprea nivosa, while 
roderipii is only known from Madagascar. 
We may take it therefore as settled beyond dispute that 
the specimen in question belongs to the species Cyprea nivosa, 
oo this identification has been the means of ascertaining, by 
rect comparison, that this interesting species also lives within 
i limits of the Indian Empire 
Amongst the collections of the Indian Museum, are two 
specimens from the Mergui oe collected by Dr. G. 
Anderson, and identified by Dr. von Martens as Cyprea vitellus
