Only a simple, pinnate, unbi-anclied fragment of a colony 

 was found. Tlie branch is weakly fascicled, and readies a 

 length of 4 cm. The minute characters of the liydrotheca^ 

 agree with Bale's description, except that the median anterior 

 tooth of the hydrotheca assumes a more upright position than 

 that figured (PI. iv., fig. 4). Bale, howevei", noies (hat " in 

 some parts of the colony the antei-ior teeth of the hydrothece 

 are without the chai-acteristic outward l)end."
