Chart 190. — Molgula arenata and Eugyra glutinans. 



The stars of solid black denote those stations from which the first-named species was recorded, the 

 dotted stars denoting those stations from which the second was recorded. Owing to the probability 

 that these two species were in some cases confused, their occurrence has been plotted upon a single 

 chart.
