The pondkrous Siliquaria. Shell brownish grey, 

 very thick, lar<?o ; whorls large, broadly con- 

 voluted and approximate near the apex and 

 below ; wavil}' dentated above the fissure, rather 

 smooth inside, thickened outside, roughly con- 

 centrically tissured ; last loose; s|)iral fissure 

 closed in the upper whorls, then drnticuliitcd or 

 articulated, aftei-wards simple.

We admit this species on account of the apparent 



distinctness of form, which may nevertheless be only 



analogous to the turbinated variety of Siliqicaria 



anguina.

 The pully Siliquaria. Shell whitish, rugose, closely 

 convoluted near the apex and towards the 

 middle ; tube moderate in size ; whorls rather 

 rough, concentrically rudely fissured ; spiral 

 fissure roundly and conspicuously articulated.

The coiled portion of this species is close and com- 

 pact, and the regular rounded articulations give a 

 chain-like appeai'anee to the fissure.

 The milky Siliquaria. Shell small, white, or biown 

 and violet, generally irregularly contorted ; tube 

 small, rather rough, rarely striated ; apical 

 whorls spirally pyramidal ; others ueaily equal : 

 fissure articulated, partly c-losed near the apex

Tliis little siliquaria is very gregarious, forming 

 conglomerated masses. Fig. I> represents a small 

 portion of one of these masses.

 The Australian Siliquaria. Shell large, thick, 

 pyramidal towards the apex, then loosened ; tube 

 large, regularly increased, very finely striated 

 on the inner side, thick, rugose on the outer, 

 concentrically fissured ; spiral fissure roundly 

 articulated, gaping near the aperture ; margin 

 thick.

Although thicker and coarser in texture than the 

 typical species, this species resembles it so much 

 that it would be difficult to distinguish the two were 

 it not for the round chain-like articulations of the 

 spiral fissure. That of iS'. (Musa is quite simple.
