PARMULARIA CYLINDRICA, new species 



Plate 56, figs. 3-8 



Description. — The zoarium is articulated. The segments are 

 bilamellar, symmetrical or not, lanceolated or irregularly lobed. The 

 zooecia are distinct, separated by a deep furrow, elongated, cylindrical; 

 the frontal is convex, rugose, perforated by large expanded tremopores. 

 The aperture is suborbicular, a little transverse, deep; the proximal 

 border is concave and bears in the middle a small rounded rimule. 

 The ovicell is endozooecial, large, little convex, of the same structure 

 as the frontal. The aperture of the ovicelled zooecia is large, elliptical, 

 transverse. 



Measurements. —

Variations. — The zoarial variations are great for there is not a 

 specimen closely resembling another. The lanceolate form is very 

 rare. The ovicells are often little visible for their convexity is very 

 slight; they are rarely tripartite. At the bottom of the separating 

 furrow of the zooecia there is frequently a very thin little salient 

 thread. 



Affinities. — This new species differs from Parmularia obliqua Mac- 

 Gillivray, 1868, in its very narrow and cylindrical zooecia. It differs 

 from Parmularia elongata in its smaller micrometric measurements 

 and its convex frontal. 



Biology. — All of our specimens were dead and deprived of chitinous 

 joints. This species is restricted to the Sulu Archipelago. Our 

 lanceolated specimen was dredged in the China Sea. It is also from 

 the same area (Straits of Malacca) that D'Orbigny received his 

 specimens of Lanceopora elegans.
