SCRUPOCELLARIA ULRICHI, new species 



Plate 9, figs. 1-3 



Description. — The articulation is complete; the segments are 

 straight or curved. The zooecia are distinct, separated by a deep 

 furrow; the inner opesium is elliptical; the external opesium is oval 

 with its point above; the mural rim is wide and rounded; the scutum 

 short. The lateral avicularium is small, scarcely salient with the 

 triangular beak turned towards the base, placed between the mural 

 rim and the vibracular chamber. The axial avicularia are small, 

 triangular, with very salient beak. The ovicell is globular, smooth, 

 placed on the distal zooecium, opening betwen the two opesia. On 

 the dorsal face the zooecia are little distinct, lozenge shaped, orna- 

 mented with scattered granulations. The vibracular chamber is 

 small, one-third the length of a zooecium, oblique, very convex; the 

 groove of the seta is narrow and regular. The radicular pore is 

 small.

Affinities. — This splendid species, named in honor of Dr. E. O. 



Ulrich, differs from Scrupocellaria diadema Busk, 1852 in its thick 



mural rim, its complete articulation and its longer vibracular chamber. 



It is very well characterized by the distal indentation of its external 



opesium. All of the specimens studied were dead.
