Pacific: Gulf of California. Cupuladria canariensis has not been 

 found in the Malay region (Harmer) or in the Philippines.

CUPULADRIA TRANSVERSATA, new species 



Plate 3, figs. 3, 4 



Description. — The zoarium is orbicular, little convex. The inner 

 face is smooth; the compartments are distinct, separated by a deep 

 furrow, irregularly polygonal, transverse, perforated by 2 or 3 pores. 

 The zooecia are distinct, joined by their thin mural rim, broad, 

 irregular, little elongated, vaguely ogival; the cryptocyst is quite 

 convex, smooth, enlarged laterally and proximally; the opesium is 

 elliptical, anterior, garnished sometimes with very short areal spicules 

 arranged without symmetry. The vibraculum is large, auriculated, 

 little salient.

Affinities. — This is the species closest to the genotype Cupuladria 

 canariensis Busk, 1859 from which it differs in the much smaller 

 pores of the inner face and in its transverse and non rectangular 

 compartments. It differs from C. breuipora, new name in its some- 

 what elongated opesium and in the presence of slight tuberosities 

 at the extremity of the radial ridges of the inner face. We have 

 found only a single dead fragment of this species but we illustrate 

 it however to show the great variety in aspect of the inner face.

CUPULADRIA DENTIFERA, new species 



Plate 3, figs. 5-8 



Description. — The zoarium is orbicular, denticulated on the edge. 

 The inner face bears lozenge shaped surfaces covered with large 

 nonadjacent granules; the peripheral denticles are long, granulated 

 and furnished with a salient longitudinal carina. The zooecia are 

 pyriform, very much arched in their distal parts. The mural rim is 

 thin and becomes merged laterally with the cn~ptocyst; the opesium 

 is anterior and oval. The vibraculum is small, auriculated, embedded 

 in the distal zooccium.

Affinities. — The lozenge-shaped cells of the inner face as well as the
