The varieties figui-ed, although rather different in form and 

 appearance^ bear the same general characters, and cannot be dis- 

 tinguished by any definite peculiarities from each other. We are 

 not acquainted with the locality of the more thickly enamelled red 

 and cream-coloured varieties which are in the collection of Mr. 

 Cuming, the others are among those brought in the Samarang 

 from the East Indian Archipelago. The four following species 

 are not easily or definitely distinguishable, still, a glance at the 

 figures will perhaps be thought to justify the attempted division, 

 which, after all, must be arbitrary.

 Conch. No. 1. p. 8. 



0. testa Ovulo secali simillima sed angustiore, minore. 



On the whole, thinner, more cyHndrical, and smaller than 

 0. secale. The specimens figured were brought in the Samarang 

 from the East Indian Archipelago.
