tubes, broken at both ends, loosely agglomerated, of a pale colour, 

 and without longitudinal iirse, shows a few spiral specimens, which 

 in the exterior form quite agree with the preceding in sculpture and 

 colour. It seems to me that the columellar and subparietal lirse 

 correspond very well to the position of the laminae in the P. cochli- 

 diuni from Australia. As Tahiti by all Continental authors is re- 

 garded as an Australian island, both groups are possibly from the 

 same locality.

This differs from the preceding chiefly in its smaller size, and 



in the colour appearing bleached as in younger specimens of V. 



cochlidium. The indicated locality is very likely erroneous. In the 



inside were found two young specimens of Vermiculus dimorphus 



(Morch), a Rocellaria* near R. cuneiformis (Spgl.), and a Diplo- 



donta, closely aUied to D. semiaspera (Phil.), but thicker in the shell, 



with thicker and more approached concentric ribs, but with feebler 



and indistinct granules. None of these genera appears to be known 



from the Mediterranean, except the second.

Animal ut Vermeti. 



The lid seems to me only different from that of Vermetus in size, 

 in consequence of the larger calibre of the shell. 



The variety y of Vermetus conicus, Dill. (p. 342), would be refer- 

 able to this subgenus, if I had not seen one and the same specimen 

 successively in the different whorls change from Vermetus (Pefalo- 

 conchus) to Thylacodus, and ultimately to Aletes. Vermetus cereus, 

 has the size of an Aletes, but shows well-developed internal laminae. 



* In the calcareous tube, at some distance from tlie aperture, there is a ring 

 of small-branched tubercles, not unlike those in the fleshy tubes of some Solenes.
