 It is surprising that the Velero has not collected more than 2 speci- 

 mens of this species considering the rather large collection of its relative, 

 C. mexicana Durham. The specimen from Sta. 1738-49 was found 

 associated with a large number of C. mexicana. 



Recorded previously from La Paz, Clarion Island, and Panama. 

 Hypotype: Cat. no. 20.2 (Sta. 1738-49). 



Material examined: Stas. 304-34 (1), 1738-49 (1). Cat. nos. 

 20.1-20.2. 



Distribution: Off Sulphur Bay, Clarion Island, 20 fms; San 

 Lorenzo Channel, Espiritu Santo Island, 13 fms.

Numerous complete corallites are present in the Velero collections. 

 The quantitative figures after the station numbers do not necessarily 

 mean that all are complete specimens, but indicate the larger pieces. 



All previous records of this species are in the Gulf of California 

 north to Carmen Island, with one depth of 31 m indicated. 



Hypotypes: Cat. no. 21.6 (Sta. 1093-40).
