Brady's figure is drawn from an imperfect specimen ; I have 

 examples from the same locality, and in these the neck is elongated 

 and terminates in a prominent lip. 



In the Malay Archipelago examples these features are not so well 

 defined. 



It has been found only at Station 25 in Area 2.

Little need be said about this ubiquitous species. Here as else-

 the trifacial variety L. trigono-marginata Parker and Jones being-
