THE MOUNT DESEET EEGION 331 



afterward (1918, p. 61) he and Levinsen (1916, p. 458) agreed 

 in placing- harmsivorthi in the synonymy of smitti. 



The zooecia present much the same general appearance as 

 those of reticulato-punctata, with the large tremopores oc- 

 cupying a large portion of the frontal wall, narrowing inward, 

 but the imperforate area proximal to the aperture is larger, 

 often more than half the length of the zooecium, but varying 

 greatly. Often this area is more raised and bears a spatulate 

 or blunt-pointed avicularium, which is usually situated trans- 

 versely just proximal to the aperture. The ooecium is about 

 the same size and shape as that of reticulato-punctata, but it is 

 not perforated as it is in that species. The aperture is simi- 

 larly shaped, but the cardelles, instead of being low and 

 broad, are unusually long and pointed. A chitinous ring is 

 present well within the border of the operculum, joining with 

 the points of the hinge teeth and fading away toward the 

 proximal border. As in the preceding species there may be a 

 rough umbonate process at a little distance behind the aper- 

 ture, and the thin-walled peristome is not encroached upon by 

 the tremocyst. The two species are undoubtedly closely allied, 

 but can readily be separated by the differences in the imper- 

 forate frontal area, the shape of the cardelles, and the pres- 

 ence or lack of perforations in the ooecium. 



Crtptosula Canu and Bassler 



In 1925 Canu and Bassler (Les Bryozoaires du Maroc et du 

 Mauritainie, p. 32) erected this genus for the reception of the 

 Lepralia pallasiana Moll (non Hincks, 1880, which belongs 

 in the preceding genus). 



Cryptosula pallasiana (Moll), 1803. PL 10, fig. 4. (Os- 

 burn, 1912, p. 240 (Lepralia), for synonymy and references.) 

 Rare, taken only once. It is common along the southern New 

 England coast. Since Hincks (1880, p. 297) confused the 

 species, it is difficult to state its general distribution, but it is 

 kno^\m from the Mediterranean Sea and the coasts of Mo- 

 rocco, Portugal, and France.
