NORTH AMERICAN LATER TERTIARY AND QUATERNARY BRYOZOA. 89 



Affinities. — This species is very little distinct from Escharipora mucronata Smitt, 

 1 872, formerly dredged in the waters off Florida. It is distinguished from it in 

 its larger and less salient mucro and in having more than three lacunae on the 

 frontal. 



The species of Smitt has not yet been rediscovered; we are ignorant, there- 

 fore, of its variations. It is hardly probable that the frontal pores would always 

 be so constant as they are drawn on Smitt's figures, but as we are not able to judge 

 the nature of the variations we are obliged to create a new species which will become 

 perhaps in the future shnply a variety. Only the figured specimen has been found. 



Occurrence. — Miocene: Santiago, Cuba (very rare).

Description. — The zoarium incrusts shells. The zooecia are large, elongate, 



elliptical, distinct, separated by a furrow and little convex. The costules are wide, 



flat, numbering from eight to ten; the lacunae are small and increase in size from 



the talon toward the zooecial axis. The apertura is semilunar, transverse, with a 



rectilinear proximal border.

Affinities. — The trace of the five oral spines as figured by Gabb and Horn is 

 sometimes visible. In its exterior aspect and the width of the costules, this species 

 is similar to Crihrilina reniformis Ortmann, 1890, and it differs from it only in the 

 micrometric measui'ements if the magnification indicated by this author is exact. 



Occurrence. — Pleistocene: Santa Barbara, California (very rare).

Variations. — The variations figured by the authors are very great; they depend 



on the number of the costules and on their width and also on the size of the avicu- 



laria. The photographs of our specimens are quite similar to the figures of Reuss
