? Caligus productus, Dana. 



U. S. Expl. Expd., Crust., vol. ii, p. 1354, pi. 94, fig. 4. 



Fix)m the Dolphin, Corypliwna^ sp. : 



6109. Latitude 38° 19' 26" N., longitude 68° 20' 20" W., surface, U. S. Fisli Com- 

 mission steamer Albatross, 18~3; 8 (? $ specimens. (Inside of gill-coyers 

 and surface of body). 



Our specimens agree tolerably well with the figures given by Kroyer,* 

 who also had it from the Dolphin; but there are some points of differ- 

 ence which render the identification doubtful until comparison can be 

 made with authentic specimens. 



Caligus rapax, Edwards. 



Hist. Nat. des Crustac^s, tome iii, p. 453, pi. 38, fig. 9-12, 1840 ; Smith, op. ciL,

From the surface :

 1871 ; 2 ^ 9 specimens. 



The specimens here recorded are the ones originally referred to this 

 species by Prof. S. I. Smith {loc. cit.). Numerous specimens of appar- 

 ently the same species have since been obtained from many other sources, 

 but as I have not been able to identify them satisfactorily, I prefer to 

 omit them from the present list. They may possibly represent a new 

 sp'ecies.
