nearly covering the earlier ones, periphery round. The 

 mouth is large and toothed. It gives me much pleasure 

 to associate M. Schlumberger's name with this form. The 

 drawings and section were submitted to him for inspection. 

 Rare.

 Horizontal section of the test. 



This handsome form is frequent in these dredgings. 

 The test is compressed, the underside much flattened, as 

 if the test had been adherent ; the chambers are convex 

 on the upperside, besides being more embracing than 

 they are underneath. They are beautifully but irregularly 

 striate, the striation following their curvature. On the 

 underside these striae are not so marked. The test is 

 polished and thin and the underside is semi-translucent. 

 The mouth is heavily lipped, and is partially closed by 

 the flap on the anti-penultimate chamber. The section 

 shows the arrangement of the chambers, the last few of 

 which are constrictedat their ends. Frequent.
