Cones J Volutes, Mitres, and Olives. 67 



specific name, episcopalis, comes from tlieLatin^ and 

 means of, or like a bishop. The Tanned Mitre (M. 

 adiista). from tlie Latin adustus — burned or parched, 

 is what is called fusiform and turreted ; that is, 

 shaped like a spindle, and having a spire or turret- 

 like termination. The streaks of colour are trans- 

 verse, that is, running the length of the shell ; or 

 in other words, they are longitudinal. This, too, 

 comes from the South Sea Islands. Fig. 2 is the 

 \Yrinkled Mitre (IT. corrugata), from the Latin 

 cornigo — to wrinkle. It is very different, both in 

 shape and markings, from the last species ; the 

 whorls, it will be seen, are angulated or pointed 

 above, and the lower part of the shell is much 

 larger than the spiral or upper portion. It is a 

 true mitre nevertheless, although not just such a 

 one as a bishop would like to wear. It inhabits the 

 Indian Ocean, the coast of New Guinea, etc. 



Olives. These, for richness of colour and bril- 

 liancy of effect, wiU bear comparison with any 

 genus of shells. Naturalists speak of them col- 

 lectively as Olivince, They belong to the Volute 

 family, and are said to number about eighty species. 

 Most of those which have reached this country 

 have come from the Mauritius, where they catch 

 them with lines baited with portions of Cuttle-
