Measurements. — Diameter of orifice, 0.14-0.18 mm. ; diameter of 

 peristome, 0.20-0.24 mm. ; distance of orifices, 0.80-1.20 mm. ; diam- 

 eter of tubes, 0.30-0.40 (max.) mm. 



Variations. — The peristomie (that is to say, the portion free from 

 the tubes) is here very erect and ahnost perpendicular to the rampant 

 surface. Calvet has noted the variations. On the rampant portion 

 the tubes are separated by a furrow or by a little salient thread. The 

 peristome is thin or thick. 



The branches are arched and formed of 1, 2, or 3 rows of tubes. 

 Our .specimens Avere dead and incrusted shells and Cellepores. 



Biology. — This species has been observed in the Pacific by only 

 two authors. Hincks (Queen Charlotte Island) and O'Donoghue 

 (Northumberland Channel). Its geographic extension appears 

 rather great, since we have found it in the equatorial belt. 



In the Atlantic region it is a species of the temperate zone and of 

 the Mediterranean. But it extends, however, almost to the Cape 

 Verde Islands in the equatorial zone, so that its discovery in the 

 Galapagos Islands is not astonishing. Moreover its paleontologic 

 distribution justifies its geographic extension. However, the fossils 

 found by Waters, 1887, in NeAv Zealand appear too small. The 

 diameter of 0.12 mm. is observed sometimes on certain recent colonies, 

 but alway.^ among the much larger tubes. The species lives very 

 rarely on algae. 



Occurrence. — Galapagos Islands, D. 2813. 



Geographic disfrihution. — Atlantic: shores of England, 23-170 

 fathoms; Gulf of Gascogny, 135-180 meters; English Channel to 

 Roscof ; shores of Norway at Bergen and at Bongostrommen ; Cape 

 Spartel, Morocco, 717 meters; Pico-Fayol; Azores, 80-130 meters; 

 Saint Vincent, Cape Verde Islands, 21 meters. Mediterranean : Cor- 

 sica on the coast from Rousse Island and to Bastia, 40 meters; Vil- 

 lef ranche-sur-Mer ; Toulon. Pacific : Queen Charlotte Islands, Ga- 

 briola and Northumberland Channel, 15-40 fathoms. 



Geologic distiibution. — Miocene, Astian, Sicilian and Quaternary 

 of Italy.
