ART. 14 FOSSIL AND KECENT BEYOZOA CANU AND BASSLER 75 



Our specimen was living but not ovicelled. It corresponds to Fig- 

 ure 112 of Smitt.

There are about six pairs of dietellae. In transparency the cos- 

 cules are indistinct and the lumen pores are very numerous; the me- 

 dian line of suture is visible; the lunate pore is often surmounted 

 by a kind of very narrow rimule (indicated on fig. Ill of Smitt). 

 On the interior the costules are not visible. The semicircular opercu- 

 lum is well chitinized and of a brownish color (Osburn) . We figure 

 it and it is bordered with a thick sclerite. 



We are the third observers of this species. Nevertheless, its struc- 

 «;ure is not yet well known, for the specimens found are very rare and 

 mcomplete. They encrust shells and corals. 



Occurrence. — Albatross Station D. 2405, Gulf of Mexico; 28° 45'

Description. — The zoarium encrusts shells. The zooecia are dis- 

 tinct, separated by a deep furrow, very large and little elongated, 

 elliptical; the frontal is very convex and formed of six pairs of very 

 broad costules, adjacent; the costules are separated by very small 

 linear lacunae attached to a median and salient suture line. An ellip- 

 tical line of lacunae a little larger outline on the frontal an elegant 

 elliptical diagram. The aperture is large, a little transverse; two 

 small lateral indentations separate a large semielliptic anter from a 

 small concave poster. The ovicell is large, smooth, carinated, hyper- 

 stomial, opened by a very narrow slit.
