There is a single specimen which seems to be typical. It is micro- 

 spheric.

There are two microspheric specimens of small size which, although 

 not very irregular in surface pattern, resemble xery closel}'' the 

 young of this species as seen in material from the Philippines and 

 other portions of the North Pacific. 



CORNUSPIRA, species (?). 



There are two microspheric specimens on one of the slides which 

 seem to be different from any described species of this genus. The 

 earliest coils are smooth; the later ones are covered by longitudinal 

 or oblique costae. These are usually distinct and do not run one 

 into the other. The transverse lines of growth are also prominent 

 in the later portions. In the largest of the two specimens the coils 

 become somewhat expanded but not compressed, the test being at 

 its greatest thickness in this portion. It is not at all like C. striolata 

 H. B. Brady; in form it is somewhat similar to a specimen figured by 

 Chapman ^ from the Tertiary of Australia. Chapman's figure does 

 not show the surface markings as in our material, but the form is 

 very suggestive. Except for the very broad later growth it resembles 

 C lacunosa. The material of C. lacunosa which I had from the North 

 Pacific showed that the last coil loses its ornamentation largely. 

 Otherwise this largest specimen is quite similar to that form.

There are several well-developed specimens of this species in 

 various stages. The largest ones show adult characters very well.
