Colurus pachypodus,’ sp. nov. 
(Pl. VI. fig. 2.] 
Sp. Oh.—Lorica slants in a straight line from above the foot 
to the middle of the breast; foot very stout, of several bulging — 
joints ; toe single, style-like, nearly as long as the foot. 
Not unlike C. caudatus, when viewed laterally, and of the 
same size, but the body is deepest in the centre, to which the 
margin of the lorica sweeps down in a straight line from above 
the foot. The foot is thick and long, and composed of several 
bulging joints. The toe is single, style-like, and almost of equal 
length with the foot. The hood sweeps down in a bold curve to 
the breast. 
Habitat.—A tide-pool, River Barrow, Co. Wexford. 
Colurus tesselatus, sp. nov. 
[Pl. VI. fig. 3.] 
Sp. Oh.—Lorica tesselated, raised at the sutures; no dorsal 
cleft, but a wide curved excavation behind; ventral cleft gaping ; 
foot stout ; toes spread wide apart. 
About the same size as O. obtusus ; the lorica of this pretty little 
species is coarsely tesselated, no cleft behind, but a wide open 
curving notch ; body deepest toward the head, ventral cleft gaping. 
The foot is short and stout; the toes, which are almost of equal 
length with the foot, are always held wide apart. A rare species ; 
four examples occurred. 
Habitat.—Bogs, Co. Wexford.
