FROM THE SOLOMOlSr ISLANDS. 555 



Museum which have it exactly similar to that of halteatum. There 

 is some doubt with regard to the identity of the shell described 

 and figured by Philippi with that of Sowerby & Reeve. Philippi 

 does not mention the dark apex, nor does he describe his shell 

 as being coloured at the base.

The Solomon-Islands specimen difters from the type of this 

 species iu the absence of the spiral lines between the ribs, which 

 are prominent and agree in this respect with some examples from 

 the Gulf of Suez, collected by and presented to the Museum by 

 the late Robert MacAndrew.

 they are identical. Length 12 mill., diam. 5.
