Three fragments, two having four chambers. 



They are not typical, the chambers being farther apart than is 

 shown in the " Challenger " illustrations, but the four costae are 

 present, bridging the depressions between the segments. Fig. 8 is 

 from the specimen that has the segments most widely separated. 

 Fig. 9 is more typical.

Six occur. Only one has three chambers, the rest being in the 

 bilocular condition. Four have the embryonal chamber smaller 

 than the one following. Millett, in his Malay Eept. Journ. E. 

 Micr. Soc, 1902, p. 520, draws attention to the fact that the multi- 

 locular forms have the embryonal chamber sometimes smaller and
