LAGENA ORBIGNYANA (Seguenza), var. CLATHRATA H. B. Brady? 



Plate 8, fig. 5. 



There are records for this form from the Atlantic about the 

 British Isles as follows: Balkwill and Millett;^ H. B. Brady;'' 

 Wright ; ^^ Balkwill and Millett ; ^^ and Heron- Allen and Earland.^- 



The British specimens do not seem to be typical of the form de- 

 scribed b}' Brady, whose typical specimens were from the Indo- 

 Pacific. In the Challenger report Brady mentions the fact that the 

 British specimens are not identical in all their characters with his 

 specimens from the Pacific.
