and filiform near the tips. It is marked by a number of grooves which run up for 

 a short distance, and also by a number of small protuberances. 



The stem is oval in section with a groove on the two flattened surfaces, 

 faintly marked in two of the specimens. 



The verrucse occur in a single row on each side of the stem, those of one ro\v 

 alternating with those of the other. They are low and truncated (0'45 mm. in 

 height), laterally compressed, with spreading bases. The diameter is 1'4 mm. at 

 the base, 0'65 mm. at the apex. 



The crenenchyma is moderately thick, and contains spiny spindles, double 

 clubs, and irregular stars with an X-shaped marking. The following measurements 

 were taken of length and breadth in millimetres : 



1. Spiny spindles, 0-19x0-07; 0'18x0'065; 0-15x0'04; O'lOxO'03. 



2. Double clubs, 0-15x0-1 ; 0'14x0'08; 0-13x0'08. 



3. Irregular stars, O'll xO'08 ; O'l xO'07 ; O'l xO'065. 



In the double clubs there are several grades, some with a fairly long bare 

 middle part and few whorls of warts, others with a very short median bare part. 

 and many whorls of warts. 



This species differs from Scirpcarella moniliforme in the number of rows of 

 verrucse, in not having a deeply grooved axis, in the size of the polyps, and in the 

 spicules.
