1862.] M. O. A. L. MORCH's review of the VERMETIDiE. 79 



This shell seems to be a very old specimea ; it has just the same 

 sculpture, only differing in a few points ; the longitudinal lirse are 

 straight and not slightly spiral ; the nodules are arranged in rings, 

 separated from each other by constrictions. Both ends are fractured, 

 so that it might have been possibly still larger. The walls have a 

 thickness of 2 or 3 m., whilst the type is very thin, nearly pellucid. 

 If this tube really is the same as the type, it must grow to a length 

 of about 60 dm. I refer this species to the present genus, merely 

 on account of the sculpture of the first whorls. 



It is, in respect of thickness, most allied to T. melitensis, Gm.
