fig. 3. 



Description. — The peristomice has a proximal pseudorimule. The 

 lyrula is wide. The avicularia are placed at the side of the aperture; 

 the small avicularia are thin and elongated; the large avicularia are 

 spathulate. The frontal is covered by small false tremopores (not 

 granulated). 



Geographic distribution. — Florida, 13-44 fathoms.

Description. — The zoarium is unilamellar. The zooecia are dis- 

 tinct, separated by a shallow furrow, more or less elongated, rectan- 

 gular; the pleurocyst is smooth or a little rugose; the frontal is very 

 little convex and bordered by numerous small areolar pores. The 

 apertura is suborbicular; the peristome is thin, a little salient, com- 

 plete with two distal spines; the lyrula is broad, flat, little salient. 

 The ovicell is globular, very salient, quite large (0.40 mm. in diameter) ; 

 the frontal area is large and bears pores. Sometimes there is a small 

 elliptical, descending avicularium at the side of the apertura. 



Measurements. — 



Aperturaf^ =0.10-0.12 mm. Zooed JLz =0.56-0.80 mm. 

 1 ila =0.12-0.14 mm. Xlz =0.44-0.50 mm. 



Affinities. — This species differs from Smittina trispinosa Johnston, 

 1838, in its larger micrometric dimensions, in the absence of a salient 

 separating thread between the zooecia, in the nongranular frontal 

 and especially in the presence of a very large ovicell. 



We have many specimens in which the zooecia are absolutely like 

 those in the figures of Verrill, 1875, and of Waters, 1908. The latter 

 author does not figure the ovicells, but he wrote that they are "large 

 and raised with a central area in which are large pores." He also 

 does not figure any frontal granulations. 



The present species is quite distinct and can not be considered as 

 a variety of Smittina trispinosa Johnston, 1838. As Verrill's species
