332 Prof. F. M‘Coy on the Classification of 
and at Maidstone, several specimens of which I saw in the 
astonishingly beautiful collection of chalk fossils belonging to the 
Rev. Mr. Image, near Bury St. Edmunds: the hand in this 
species is much compressed as well as the carpus and arm, and 
all covered with large scattered curved spinose tubercles (largest 
on the outer and inner edges of the hand, carpus and arm) with 
an intermediate smaller tuberculation ; the basal part of the tand 
is subrhomboidal, slightly longer than its width ; carpus small, its 
greatest length and width equal, proximal end only half the size 
of the distal end, abruptly formed by a deep sinus in the proximal 
half of the inner margin (like that of the right arm of the recent 
Callianassa subterranea); penultimate or immoyeable finger 
straight, rapidly tapering to an obtuse point, its length only 
equaling that of the hand from the base of the finger to the 
carpus ; moveable or last finger a little longer, not tapermg so 
rapidly, and incurved at the apex, each finger with a row of 
blunt hemispherical tubercular teeth less than their diameter 
apart. Average length of moveable finger 2 inches 6 lines, 
from thence to the carpus | inch 9 lines, width at base of fingers 
1 inch 9 lines, width of carpus 1 inch 1 line, width at distal 
end 1 inch 3 lines. I have affixed the name of Hnoploclytia 
Imagei to this, the largest and most mteresting of the mesozoic 
Crustacea, to commemorate the zeal and taste of the amiable 
owner, whose exquisite collection of cretaceous fossils would, if 
more fully known, greatly increase our knowledge of the fossils of 
this period. 
Enoploclytia brevimana (M‘Coy). 
Sp. Char. Carapace subcylindrical or slightly compressed, ave- 
raging 3} inches long and | inch 9 lines deep ; rostrum strong, 
pointed, with three or four large pointed teeth on each side, 
margins of the orbits with strong spines; surface closely 
studded with small tubercles and large scattered spines ; 
hands short ovate, length little more than the depth of one 
side of the carapace, length of the moveable finger about equal 
to, from its base to the carpus, and a little longer than, the width 
of the hand, both fingers incurved at the tip and set on the 
inner edge with a row of blunt hemispherical teeth half their 
diameter apart ; carpus subtrigonal, a little longer than wide ; 
arm compressed, about one-third longer than wide ; surface of 
hand and carpus with many large, curved, spose tubercles, 
and an intermediate, close, smaller tuberculation ; length of 
moveable finger 1 inch 1 line, from thence to carpus 11 lines, 
width of hand 1 inch. 
The very short small ovate hands easily distinguish this spe- 
cies from the other two.
