62 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 16 



Remarks: This species resembles A. {Astrangia) equatorialis, new 

 species in the slender paliform teeth but differs by the shallow calice and 

 form of the paliform teeth. The species also resembles A. {Astrangia) 

 haimei Verrill but differs by the fewer number of paliform lobes. The 

 commensal worm tube in the base causes a resemblance to the genus 

 Heterocyathus, but the dentate upper margins of the septa place it in 

 the genus Astrangia. 



Dimensions of corallite: Height 6 mm, calices 4.5 by 5 mm, depth 

 of calice 1.5 mm. 



Holotype: AHF no. 4. 



Type locality : Sta. 1062-40, off Willard Point, Gonzaga Bay, Gulf 

 of California, 16 fms. 



Material examined: The type.

The specimens from Station 1071-40 are not quite typical in that 

 they have one more paliform lobe per septum than is present in normal 

 members of the species. 



This species has been recorded in the Gulf of California north to 

 Concepcion Bay at 11.5 fms and 31 m. It is in the Pleistocene at Santa 

 Inez Bay. 



Material examined: The holotype (Univ. Calif. Mus. Paleo. No. 

 14827, Concepcion Bay, Lower California, 7 fms) and Stas. 549-36 

 (numerous individuals), 1048-40 (numerous individuals), 1071-40 

 (3). Dawson Sta. 53 (1). 



Distribution: Angel de la Guardia Island, 11-40 fms; San Felipe 

 Bay, 2y2 fms. Dawson Sta. 53 is at Cabeza Ballena, near Cape San 

 Lucas, shore, Nov. 9, 1946.
