 niartii, the generic name Chorizophora must be 

 retained.

The specimens which I referred to Bugulopsis Peachii 

 mnst be transferred to the Bugula elongata of Nord- 

 gaard. The general resemblance of the tMO species is 

 remarkable : in form of zoojcia and ooecia they are 

 almost identical ; moreover the peculiar sculpturing of 

 the latter is of similar character. The chief point of 



difference consists in the occasional development in 

 Bugula elongata of a very minute avicularium, situated 

 on the middle of the side of the zooecium, from which it 

 usually hangs as it were backwards, as shown in the 

 woodcut here given ; but these avicularia are rarely 

 developed, and there may be an entire zoariura without 

 any avicularia. The otlier points in which the species
