This fpecies feems to come between the Corallina ob- 

 tufata and the Corallina cylindrica that follows. It dif- 

 fers from the firft in being round at the top of the joints 

 and not at the bottom ; and likewife in being more {len- 

 der, alfo growing thicker towards the top. It differs 

 from the latter by the joints being a little comprefTed and 

 more diftant ; it is alio thicker and fofter. 



It is found among the Weft-Indian iflands.

This Coralline I lately received from Mr. Greg, pre- 

 ferred in fpirits, trom the Weft Indies; when it was 

 fhifted into clear fpirits, there hung to it a clear gelati- 

 nous fubftance, which the internal part appeared to be 

 full of. Upon opening fome of the joints, they alfo were 

 full of minutely branched tubes ; fo that the tubular hol- 

 low appearance, as defcribed by authors, proceeds from 

 their having diffeded only dried fpecimens. The joints 

 feem rather larger at top than at bottom in recent ipeci- 

 mens.
