The form illustrated and identified as Argilloecia cylindrica Sars 

 by Colalongo (1965) is identical in lateral outline with Anchistrocheles 

 antemacella. The associated ostracode species of this Le Castella 

 (Plio-Pleistocene) assemblage have close counterparts in the modern 

 abyssal assemblages from which A. antemacella is identified (Benson, 

 pars. comm.).

Figure 63 



Material. — A single specimen collected living in carbonate sand 

 among patch reefs, just below tide level, at Ambariobe, Nosy Be,

 mm, height 0.21 mm. 



Affinities. — The soft parts of this specimen identify it as a ij 

 female of Anchistrocheles.
