 Mem. 20, pp. 30-31, pi. 6, figs. 1, 2. 



A rather large specimen (90 mm long, 70 mm wide, and 65 mm 

 high), with well-preserved calices is present in the collections. One large 

 calice has 40 septa and the columella appears to be dividing in half. 

 The station locality extends the range of this species north of the San 

 Lucas faunal boundary. 



This species has been recorded in the Gulf of California, Guaymas, 

 Acapulco, and Tehuantepec, bathymetric occurrence unknown. 



Hypotype: Cat. no. 38.1 (Sta. 1787-49).
