Pound on the south coast of England, and obtained by 
Mr. Ball in great numbers in the cavities of a Rhizostoma , 
at Youghal. To this genus also belongs the C '. Gammarus 
Galba of Montagu, found on the south coast of Devon, and 
met with by Mr. Hyndman, on the Dublin coast, in the 
pouches of Rhizostoma Cuvieri . Mr. Spence Bate regards 
this as synonymous with Montagu's species.
