I have received fpecimens from the Eaft Indies of a Ser- 

 tularia very like this in appearance, but fmaller, where 

 both the denticles and branches are exadtly oppofite, and 

 the joints both on the ftem and branches much clofer to- 

 gether. The S. Lonchitis was found in the harbour of 

 Dublin.
