 '"' 3. Limicolaria turhinata Lea; lieeve, Conch. Icouica, i?w- 

 limus, fig. 605. — From Grand Cape Mount. At the same 

 locality many specimens of L. tenehrica Rve and spectralis 

 Rve are found , which , according to Dr. Dohrn , should 

 be considered merely as varieties of turhinata Lea , the 

 oldest name of the species. A few specimens from the 

 Junk River are collected by Stampfli. 



4. Perideris torrida Gould. — One specimen from Mills- 

 burg on the St. Paul's River; a few others without exact 

 locality and from the Junk River, those from the Junk
