There is little to be said about this common species. In the 

 Malay Archipelago it is nowhere abundant, but is scattered all ovfr 

 the region. 



Lagena clavata d'Orbigny sp. var. seiigera var. n., plate VIII. fig. 9. 



Lagena Isevis Montagu sp. (var.) Brady, 1884, Chall. Fibpt., 

 pi. lvi. fig. 30. 



Differs from the type in having at the aboral end a cup-shaped 

 indentation surrounded by a circle of setae. 



In Oolina striaticollis d'Orbigny, and some of the figures of 

 Lagena tenuis Bornemann, as interpreted by Reuss, the free ends of 

 the ribs extend beyond the base of the shell and have a similar appear- 

 ance ; but in the variety under consideration the ribs are entirely 

 wanting. Still the form is interesting, and worthy of notice as form- 

 ing a connecting link between the smooth and the striated Lagense. 



In the Malay Archipelago it is widely distributed, and is far more 

 abundant than the type.

This form is very well represented in both Areas, and the 

 specimens form an unbroken chain from L. clavata to the distomatous. 

 L. elongata.
