REPORT ON THE AMPHIPODA. 1035 



'• Lower Antennae also with very long flagellum, attached under the head. 



" First and Second Gnatkopods slender, with small, subcheliform hands. 



" First and Second Peraeopods narrow ; the third joint broad. 



" Third and Fourth Peraeopods retroverted ; the fingers small. 



'• Fifth Peraeopods much shorter than the Third or Fourth ; the first joint much 

 dilated below and behind. 



" Uropods biramous ; the rami of the third pair laminar and setose. 



" Tel son more or less deeply cleft." 



In regard to this definition it may be remarked that the likeness between the two 

 mandibles does not extend to the secondary plate, since that on the right mandible is as 

 usual of weaker construction than that on the left ; of the third and fourth perseopods 

 it is rather the two terminal joints (and perhaps the third) that are retroverted than the 

 whole of the limb ; notice might also well be taken, among the famdy characteristics, of 

 the gland-cells in the first and second peraeopods.
