divergence of the tubes directed toward the adjacent pinnules. The 

 median section made on a pinnule gives the longitudinal section ; it 

 is analogous to that of Tnmcatula. The tubes are subcylindrical, 

 widened toward their extremity, and open on the two faces inferior 

 and superior of the pinnule. The nematopores completely surround 

 the base of the zoarium ; their orifice is much smaller than that of the 

 tubes.

We have been fortunate enough to discover the ovicell of this 

 charming cupuliform and pedunculated species. It is a vesicle placed 

 on the edge of the zoarium, of which it arrests the development and 

 which ramifies between the fascicles. It is limited, smooth, little con- 

 vex, and provided with special walls. 



This species is therefore not at all a DUcocytis. We maintain it 

 provisionally in this genus, for the number of specimens collected 

 does not permit us to make sections and to establish the nature of the 

 tubes and adventitious pores. Perhaps it will be necessary to classify 

 it in Bicavea D'Orbigny, 1854, a genus in wdiich the ovicell is still 

 unknown.

Colony fastened at the base, where part of a cylindrical rather 

 short peduncle is widened rather abruptly above, giving rise to sim- 

 ple or bifurcated branches, diverging horizontally, but joined at 

 their base. Each of these branches is short, depressed, covered 

 below by a thin epitheca and above by oblique, pyriform cellules. In 

 the middle of the colony, above, may often be noted one or two 

 ovarian vesicles, smooth, oval, semiconvex, and having within a canal 

 which communicates with the interior of the colony. (Translation 

 after D'Orbigny, 1854.)
