6 EXOTIC CONCHOLOGY. 



diversify them with masses of that same deep colour that characterises the inner 

 lip. The ap^ture is of slightly empurpled and brilliant white, with the position 

 of the varices distinguished by rosy horizontal markings. The M. Regius of 

 Chemnitz, vol. 13, is not this shell, but the M. Erythrostoma of the Zoological 

 Illustrations. 



Family— TURBINELLIDjE. 



Base of the shell produced into a long channel ; the spii-e generally short : the pillar 



often toothed, outer lip thin. 

 Si(b-Fam>!y—¥vsiNJE.. Shells generally fusiform and slender : the base elongated ; the 



spire lengthened and acute : piUar smooth, outer lip thin. 

 Genus — Ftjsus. Shell long, slender: both extremities much produced ; spire attenuated, 



turrited, and of nearly equal length with the aperture.

This Aru Trumpet at once attracts our attention by the extraordinary 

 appearance of the upper portion of its spire, which scarcely seems belonging to 

 the shell, and looks as though a Pupa had been inserted in the place of its natural 

 apex. The specimen we have figured is in an exceedingly young state, and certainly 

 differs much from the d escription we have given above ; its peculiar spire, how- 

 ever, at once betrays its parentage. It is of a much lighter colour, far less ventri- 

 cose, and its tail much longer in proportion than the adult shell, of which we will 

 now proceed to give a description. 



Shell fusiform, ventricose, transversely grooved, tawny red, with the whorls 

 angulated and flattened above : the angle crowned with nodulous tubercles : the 

 upper part of the spire cylindrical and roughened with tubercular plaits, and 

 proboscidiform : apex mammillary : lip smooth within. Habitat New Guinea. 



The specimens I have seen are usually about six inches in length, and not 

 very massive ; but if we may believe the older authors, they attain a far greater 

 size and thickness. From the description Linneus has left us of the S like form 

 of its pillars, I am inclined to think he had not seen the original shell, but had
