In a sample from KKm I found a small Amphora measuring 

 ]. 0,028 mm., b. 0,003 mm., striæ 15 in 0,01 mm. In its shape it exactly 

 agrees with the species figured by A. S. Atl. tab. XXVI, fig. 16 which 

 Cleve (Syn. II, p. 129) regards as identical with Amph. ostrearea Bréb. 

 var. vitrea Gl. 



229. A. proboscidea (Greg.?) Gl. Gl. Syn. II, tab. III, figs. 19 — 21. 



Solitary in a sample from LN. 



Area: Portoseguro, Bahia, Java, Bali Sound. 



The form found by me is more capitate than figured by Gleve 

 and resembles in that respect A. Kittoni L. Fortm. L. Fortm. Ceylon 

 tab. I, fig. 7.

233. A. Terroris Ehr. A. S. Atl. tab. XXV, figs. 17-19, 33, 34-36. 

 KKt (3 samples). 



Area: probably ubiquitous. 



In two samples from KKt I found a form agreeing with A. monili- 

 fera Greg.? in A. S. Atl. Tab. XXV, fig. 32 (from Java). As to this form 

 Gleve (Syn. II, p. 122) says that it „probably is a frustule of A. costata 

 or Terroris in the state of division".
