an exterior eye upon an anterior ex- 

 tremity. At the extremity of tlie muz- 

 zle is the mouth, which is armed with- 

 in with numerous horny teeth in pairs, 

 elongate or hastate. The- shells in- 

 habit the seas of the warmer countries, 

 especially those lying between the 

 tropics, where they occupy sandy 

 coasts, with a depth of ten or twelve 

 fathoms of water. We have repre- 

 sented a number of fine species in this 

 number. Conns imperalis (Fig. 10) 

 is a fine species of white color with 

 bands of greenish yellow or tawny 

 color, ornamented with transverse, 

 cord-like articulated lines of white and 

 brown. Inhabits Philippines and Algoa 

 Bay. One of the largest species is 

 Conus geographus (Fig. n) which 

 sometimes attains the length of six or 

 seven inches. It is shaded with white 

 and brown and found in Ceylon. 

 Among the non-crowned species we 

 have Conns tcsscllatus, (Fig. i la) com- 

 mon in the Indian Ocean, Ceylon, etc., 

 its anterior part is violet in the interior. 

 The spots with which it is surrounded 

 are of a fine red or scarlet or a red 

 ejad color upon a white ground. 



We figure three varieties of Conns 



auuniralis (Figs. 12, 13, 14). They 

 are natives of seas that wash the 

 shores of the Molucces; are beautifully 

 marked varieties, of a brownish citron 

 color, marked with white spots nearly 

 triangular, with tawny bands painted 

 in a very fine tracery. This is a very 

 handsome species, and presents many 

 varieties not here figured. 



Among the species which seem al- 

 most ready to become cylindrical, may 

 be noticed Conus nobilis (Fig. 15) a 

 rare shell of yellowish color approach- 

 ing citron, ornamented with white 

 spots. The golden drop Conns textile 

 (Fig. 16) is yellow in color, ornament- 

 ed with waving longitudinal lines of 

 brown and white corded spots edged 

 with tawny color. The glory of the 

 sea, Conns gloria maris (Fig. 17) is 

 white in color, banded with orange, 

 and reticulated with numerous triang- 

 ular white spots edged with brown. 

 This is a native of the East Indies, 

 and one of the most beautiful shells of 

 the whole group. 



The genus Oliva is so named from 

 its resemblance in form to the olive. 

 Its nearly cylindrical shell is slightly 

 spiral, polished and brilliant as in the
