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 hand 

 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 immoveable 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 tapering 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 1 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 Enoploclytia 

 Imagei to this, the largest and most interesting 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 1 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, spinose tubercles, 

 and an intermediate, close, smaller tuberculation ; length of 

 moveable finger 1 inch 1 line, from thence to carpus 1 1 lines, 

 width of hand 1 inch. 



The very short small ovate hands easily distinguish this spe- 

 cies from the other two.
