PLATE 80 .

Fig. 1 - 13. Euryrterus remipes. 
1. A young individual, dorsal side. 
2. A young individual, ventral side; showing the anterior feet, the postoral plate, with the 
articulations of all the parts nearly entire. 
3. A young specimen, showing the upper side of the body, which is entire, except the poste¬ 
rior spine and a part of the anterior feet. 
4. A large individual of nearly the full size to which this species attains, lying upon its hack, 
and having the lower or ventral side of the articulation removed; showing therefore the 
inner side of the carapace, and the articulations of the thorax and the abdomen. The 
anterior feet are partially preserved, and the swimming feet are entire, the lower side 
being shown. At s, s is the line of the suture by which a triangular piece is attached to 
the sixth joint, forming the fixed ramus of the chela, and over the upper surface of which 
the free extreme joint moves. The articulation of these parts with the body is not clearly 
shown, from the incompleteness of the specimen, the parts to which they were attached 
having been removed. 
5. An individual preserving more than usual convexity of body. The head and eyes are very 
perfect : the anterior feet are lost, but the swimming feet are well preserved in all their 
parts, and the indented extremities are strongly marked. In the contraction of the extreme 
joint, the fixed branch of the chela below is nearly covered. In comparing the swimming 
feet in figures 4 and 5, it will be observed that in the former the lower side, and in the 
latter the upper or dorsal side, is seen. 
6. A small carapace preserving the eyes. 
7. The abdominal articulations and the posterior spine, separated from the thoracic rings. 
8. An imperfect caudal spine, with the last two articulations of the abdomen. 
9. The caudal spine : a lateral view of a specimen not quite entire. The lefthand is the dorsal 
side, and the general form is triangular, becoming more convex on each side of the dorsal 
edge towards the base. 
10. The ventral side of a fragment, showing, on the lefthand side of the figure at a, the ar¬ 
ticulations of one of the swimming feet, with the large maxillary joint, which is nearly 
in its natural position, while the opposite one is displaced. The basal articulations of the 
anterior feet are likewise seen more distinctly than in any other specimen : the first and 
second are broken oft', while the third is nearly entire, and preserves the minute spines 
on the lower side of each joint. 
11. A fragment showing the inner side of several of tlie thoracic articulations, and preserving 
the anterior feet nearly entire, with the articulations of one of the swimming feet : the 
place of attachment of these is obscured by some of the plates of the body below. 
12. The post-oral plate of this species. 
13. An enlargement of the centre of the head of fig. 5, showing the small oculiform spots.
