Very numerous and of varying size and shape. The orifice 

 and internal tube are subject to great variation. Locality : 

 Many .stations. 



PL 15, fig. 1. The orifice is small and somewhat hooded, and 

 the test often inclined to be apiculate. Locality : Many stations. 

 Rare. 



PI. 15, fig. 2. An elongate variety. Locality: Uncertain. 



Only one found. 



PI. 15, fig. 3. An interesting variation, the body of the test 

 being partly clear and partly opaque. The curiously produced,, 

 flattened mouth, which appears to be divided or pinched in at the 

 centre, points to its being allied to the one figured + PI. 14, fig. 2.* 

 The entosolenian tube is absent. t Locality : Nos. 21-26, 34, 38, 

 42, 44. 



+ P1. 14, fig. 2. Locality: Uncertain. 



+ P1. 14, fig. 4. The slightly elongated form predominates. 

 Locality : Many stations, including Nos. 6, 8 ; after No. 22 only 

 at one or two stations. 



+ P1. 14, fig. 5. This compressed variety of the above is found 

 sparingly at a few stations, but tests that are much more com- 

 pressed, and pointed towards the aperture, are frequent.
