 The specimens from Santa Catalina Island consist of 2 broken ma- 

 ture individuals and one intact specimen. 



There are 2 other specimens from Bottom sample 481 (Cartago Bay, 

 Albemarle Island, 12 fms) the largest of which has a height of 9 mm 

 and a calice diameter of 2.5 mm. They have 3 cycles of septa developed, 

 with the primaries more exsert than the later cycles. Well-developed 

 costae are present and extend to the base as lines of granules. The calic- 

 ular fossa is very deep. These specimens might represent the young of the 

 form described by Vaughan (1906) as D. galapagense. 



On the Pacific coast, this species is known from Monterey Bay to 

 Point Pinos at a depth of 56-145 fms; off Panama, 742-861 m. Also 

 found in the Mediterranean, Indian, and Atlantic Oceans at depths 

 ranging from 160-2000 m. 



Hypotype: Cat. no. 48.2 (Sta. 1848-49). 



Material examined: Stas. 1027-39 (1), 1848-49 (2). Cat. nos.
