 fig. 3. — Bate and Westwood, p. 45. 

 This species was first found by Col. Montagu, and we have 

 obtained it in the neighboiu^hood of Plymouth ; and Mr. E. Q. 

 Couch has found it among confervce, at Lariggan rocks, Mount's 

 Bay, Cornwall.

 segments of the body.

 p. 1056. — Bate and Westwood, p. 52. 



All round our shores, amongst stones and weed. This animal 

 appears to watch and protect its young, they creeping about the 

 parent and looking like small branches of weed attached to her

 that it is not uncommon among corallines in Mount's Bay. 



This species appears to have a near representation in different 

 parts of the globe. Gap)reUa geometric a, of the United States ; and 

 Caprella rohusta, from Rio Janeiro, as well as Caprella nodosa, from 

 the Mauritius, would no doubt be considered the same species as 

 this were they not found in such very distant parts of the globe.
