 " Taken from the stomach of a young seal which was shot in lat. S2°| N. It is rather difficult 



to determine whether this animal belongs to the genus Gammarus or Talitrus ; but this 



difficulty may possibly arise from the antennas of many of the individuals being imperfect.

 The Caprella scolopendroides of this and of Ross's earlier Appendix is perhaps the same as 



jEgina spinosissima, Stimpson (see Note on Ross, 1826, p. 130, and Note on Miers, 



1877, p. 468). The reference to Cancer ampulla, Phipps, mentions fig. 2, instead of fig. 3, 



which is the number in the original both in the text and on the Plate. This error in the 



reference to Phipps' species is, for some reason, of common occurrence.

 l'Academie des Sciences de Bordeaux pour 1841.) 



This author thinks that it is the same species which occurs in brooks and wells, variously 

 coloured, and known by many different names, of which he gives derivations ; chevrette 

 from the Latin caprella ; crevette , from crabette, petit crabe ; gammarus from caris 

 marina, " un nom hybride forme de grec et de latin" [!]; agrouelle or egrouelle from 

 Gesner's scrophulaj aquatica;. The three pairs of pleopods, he says, are called pattes 

 branehiales. In regard to the branchial vesicles, of which he does not admit the branchial 

 function, he curiously says that he has never been able to find them. He denies that the 

 males carry about the females between their feet, though he allows that some of these
