A CORNISH FAUNA. 



Genus, Protella. — Dana. 



U.S. JExpl. Exp., p. 812. 



Like Proto, but having rudimentary appendages to the twc 

 somites succeeding the hands. 



Protella phasma. — Montagu, Trans. Lin. Soe., vol. ii, p. 66, pi vi, 

 fig. 3. — Bate and Westwood, p. 45. 

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

 obtained it in the neighbourhood of Plymouth ; and Mr. P. Q,. 

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

 Bay, Cornwall. 



Gtenus, Caprella. — LinncBus. 



Like Protella, but without any appendage to the two central 

 segments of the body. 



Caprella linearis (Skeleton Shrimp.) — Linnceus 1 Syst. Nat., ii, 

 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 

 body. 



Caprella lobata. — Mailer, Zool. Ban., Frod., 197. — Bate and 

 Westwood, p. 57. 



We have taken this species in Plymouth Sound, and Mr. 

 Edward has sent it to us from the Moray Frith. 



Caprella acutierons. — LabrieWs N. Bict. de. Hist. Nat., 2nd ed., 

 vol. vi, p. 433. — Bate and Westwood, p. 60 



Taken in Plymouth Sound ; and Mr. P. Q. Couch informed me 

 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. Caprella geometrica, of the United States ; and 

 Caprella robusta, fromPio 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. 



Caprella hystryx. — Kroyer, Nat. Hist. Tid., iv, 603, pi. viii, 

 fig. 20, 26. — Bate and Westwood, p. 63. 

 This species has been found on the shores of the North of 

 England, and also in Plymouth Sound.
