 pp. 37-38, pi. 10, figs. 2, 6. 



As observed in the specimens here reported upon, the lateral calices 

 of this species are usually 4-5 mm long and 8-11 mm in diameter. Oc- 

 casionally the fused fourth cycle septa produce a large, blunt dentation. 



The calices are shorter than in D. oldroydi Faustino and the colum- 

 ella is more elevated. In D. oldroydi the first and second cycle septa are 

 considerably exsert ; as a result, the ^dges of the calice have a distinct 

 serrated appearance. In D. califomica the same septa are only slightly 

 exsert, thus the upper edge of the calice has a nearly smooth profile. The 

 costae around the calice edge are much more prominent in D. oldroydi 

 than in D. califomica. 



This species has been recorded previously from off the coast of 

 Lower California in 23 fms.
