664 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 14 



Type locality, Hancock Station 190-34, Albemarle Island, Galapagos, 

 0°55'S, 90°30'W, at 58 fms. Also at Station 201-34, Hood Island; and 

 453, Gardner Island, Galapagos, 35 to 65 fms. 



Platonea elongata new species 

 Plate 69, fig. 1 



Zoarium adnate, slender, unbranched ; the dorsal lamina narrow, 0.95 

 mm at its widest part, while the high fascicles project much beyond it 

 to a width of 1.50 mm. The fascicles are regular and alternating on each 

 side of a distinct midline, moderately high (0.40 to 0.50 mm) ; the peri- 

 stomes all connate in series of 6 (5 to 7), their apertures rounded or 

 slightly quadrate, 0.09 to 0.10 mm in diameter. There are no free 

 peristomes or vestigial tubules at the lateral margin. 



The ovicell is very elongate, its lobes occupying 7 interfascicular areas 

 on each side and extending laterally the width of the lobe. The ooecio- 

 pore is located in the usual position beside the first peristome of a fascicle, 

 but unfortunately the ooeciostome is broken away. 



The zoarial characters are much like those of P. veleronis n. sp., but 

 the lobe is much narrower. The most important character is the great 

 length of the ovicell, covering 7 interfascicular areas on each side, while 

 in the 11 specimens of veleronis from the Galapagos Islands there are 

 never more than 3. There are no intermediate conditions presented and, 

 until contradictory evidence is discovered, this must be considered a 

 different species. 



Type, AHFno. 119. 



Type locality, Hancock Station 1064, off Santa Barbara Island, 

 southern California, 33°30'01"N, 119°02'20"W, at 27 fms, one colony. 

 Also at Station 1143-40, off Portuguese Point, southern California, 

 33°44'59"N, 118°22'35''W, at 16 fms, one colony. 



Genus FASGIGULIPORA d'Orbigny, 1847 



Like most of d'Orbigny's descriptions, this one is very brief, "well 

 characterized by its shell-like (testaces) branches, smooth exteriorly, 

 terminating at the upper extremity in a fascicle of rounded, open cells." 

 (Transl.) 



Canu and Bassler, 1920:808, add the following: "This genus differs 

 from Frondipora in its long fascicles not arranged on a single side of 

 the zoarium."
