206 Mr. Templeton’s Description, St'c. 
The next ring or neck is very short, and bears the second leg. 
This leg is slender, longer than any of the succeeding ; the joints 
after the second being in succession, each longer than that preced- 
ing ; spiny ; the apex carrying a very long, gently curved claw. 
The five succeeding rings are tolerably large, of nearly equal 
breadth, the central rather the longest, and each supporting a pair 
of legs, which are five-jointed ; the second joint very long and 
thick, the rest about one half as long and spiny ; the fourth and 
fifth toothed on the posterior edge, and the fifth carrying a short, 
strong, hooked claw. The rest of the rings are successively 
smaller, except the caudal, which extends a length equal to that of 
two which precede it ; the first three are furnished with swimming 
feet, which are double jointed, the apical carrying two semicir- 
cular lamellae, articulated by one extremity, the curved edges of 
which are furnished with very long hairs, and the straight edge of 
one with two blunt wavy spines. The caudal ring has a fissure 
on each side dividing its edge into three parts, the central termi- 
nated by a pencil of hairs, the lateral of each side with a seven- 
jointed style, whose first joint it conceals ; the joints of these 
styles are elongate, and apically furnished with two or three 
spines or long hairs, those from the terminal very long. 
This singular little animal, which I have inscribed to my friend 
Mr. Westwood, would seem to take precedence of all the genera 
in the division Amphipoda of Latreille, to which I believe it cor- 
rectly belongs. It resembles, however, very much in its gait and 
habits the Srpiillce, and the resemblance is still more striking, 
from the excessive developement of the hand, and the mode in 
which it is carried, pressed close up against the cephalic ring ; 
and also in the form of the swimming feet. Nevertheless the 
chelae, the simply clawed feet, the styled tail, subpedunculate eye, 
and the mode of origin of the antennae, reduce it to its proper 
place among the Gammaridce, but in a section distinct from any 
as yet described, [and nearly allied to Tanais and Rhcea of M. 
Edwards. — J. O. W.]
