Mea^ufrements. — Diameter of orifice, 0.08 mm.; width of lines 

 (peristome), 0.12-0.14 mm.; interior separation, 0.20-0.30 mm.; di- 

 ameter of oeciopore, 

 0.08 mm.; diameter of 

 oeciostome, 0.14 mm.; 

 number of tubes to the 

 fascicle, 4 ; diameter of 

 protoecium, 0.16 mm. 

 (Waters). 



On the dorsal the 

 tubes are cylindrical. 

 The oeciopore is ellip- 

 tical, nonsalient; it is 

 the first tube of a fasci- 

 cle. The figure of 

 Neviani, 1905, is perfectly correct, and we reproduce it. The tubes of 

 the same fascicle are not always rigorously adjacent; they. appear 

 then interrupted. The micrometric measurements taken from the 

 figures of Waters, 1922, correspond almost to ours. 



The colonies are very variable and exhibit triangular, rounded, 

 and bifurcated lobes; the linear forms are short and rare. 



A^nities. — This species differs from Tubulipora liliacea Harmer, 

 1898, in its smaller orifice (0.08 mm. and not 0.10 mm.), in its inter- 

 rupted fascicles, in the elliptical form of its oeciostome, and its smaller 

 and more slender colonies. 



The specimen figured by Busk, 1875,* shows analogous dimen- 

 sions, and it is probably the Mediterranean species.
