1915, F.K A. p 654.) Very abundant, universally distributed, 

 and the specimens often attaining a very large size. There is 

 always some uncertanty whether these abnormally large speci- 

 mens are true Lagenx, or primordial chamliers of l^olymorphinx. 

 As they are often more or less compressed, or irn gular in shape, 

 it seems probable that they are not Lwienas. Individuals of true 

 L. f/Johosa with double apertures were recorded at Stations I and 

 Axilla, and feebly sulcate specimens at Stations I and V. (M.)

 Subject to extraordinary variations at Station I, where it was 

 abundant. At this station, elongate, curved, and pedunculate 

 forms occurred, and also an individual with two separate terminal 

 portions. The specimens also present an extraordinary range in 

 their surface markings, from practically a smooth surface to coarse 

 striae, whilst ;dways preserving the general characteristics of the 

 species. (P.) (M. as L. caudata Parker A- Jones.) (M. 1906 =
