Lagena marginata, Walker 4- Boys. 



Occurrence.— ^i2i. 10, 1485 £ms. ; 11, 1417 fms.; 13, 1050 £ms. ; 19, 

 1995 £ms.; 20, 1215 £ms.; 21, 2195 £ms.; 45, 2107 £ms. ; 48, 2298 £ms.; 

 105, 2400 fms. ; 140, 2476 fms. ; 148, 2620 fms. 



Lagena marginata, Walker Sf Boys, var. semimarginata, Reuss. 

 Occurrence.— ^i^. 3, 2715 fms. ; 10, 1485 fms. 



Lagena marginata, Walker Sf Boys, var. seminiformis, Scliwager. 



Lagena seminiformis, Schwager ('66), p. 208, pi. 6. fig. 21. 



L. marginata, Walker & Boys, var. seminiformis, Scliwager ; Millett ('01), Rep. Malay 

 Foram. p. 620, pi. 14. fig. 3. 



Although regarded as an essentially deep-water species by Brady, Millett 

 obtained it from shallow-water dredgings in the Malay Archipelago. 

 Occurrence. — Sta. 21, 2195 fms. 



Lagena ventricosa, Silvestri. (Plate 54. fig. 9.) 



Lagena ventricosa, Silvestri ('03), p. 10, woodcuts figs. Qa-e. 



Our examples exactly agree with Silvestri's figures of L. ventricosa, from 

 the Miocene of Piedmont. Dr. Silvestri points out, in his description, the 

 probable alliance of this form with Brady^s so-called Lagena apiculata 

 ('84, pi. 56. figs. 17, 18), a species which is normally subcylindrical and 

 elongate, whilst L. ventricosa is depressed and subovate. 



Occurrence.— ^ta. 11, 1417 fms. ; 48, 2298 fms. ; 148, 2620 fms. 



Lagena staphyllearia, Sclnvager, sp. 



Occurrence.— ^i^. 3, 2715 fms.; 10, 1485 fms.; 20, 1215 fms.; 48, 

 2298 fms. 



Lagena trigono-marginata, Parker Sf Jones. 

 Occurrence. — Sta. 105, 2400 fms. 



Lagena wrightiana, Brady. 



Our specimen is rounder in outline than Brady's figured example, and has 

 a rather sharp marginal keel. 



Occurrence. — Sta. 105, 2400 fms. 



Lagena lagenoides, Williamson, sp. 

 Occurrence.— ^i^. 105, 2728 fms. ; 19, 1485 fms. 



Lagena quadralata, Brady. (Plate 55. fig. 10.) 

 Lagena quadralata, Brady ('94), p. 464, pi. 61. figs. 3 a, b. 



This rare species has been found only in two localities previously, viz., 

 south of Australia and in the S. Atlantic ; both in deep water.
