DECAPODA ANOMURA. 
Tribe LITHODEA. 
In this tribe, the abdomen, or the urogastric portion of the body, com- 
monly called the tail, is always covered on its outer surface with calcareous 
plates arranged in three or five rows. The external antennae are always 
much shorter than the thorax. The last pair of feet are very small, different 
from the rest in shape, and are concealed under the hinder edge of the 
thorax.

The carapax forms a broad, thin shield, of very uneven surface, completely 
hiding the legs, antennae, abdomen and all inferior parts of the body, which 
seem when viewed from below to be placed in the bottom of a cup-like cavity, 
and only the tips of the eyes are seen from above in the angle between the 
base of the rostrum and the interior margin of the carapax. — (Stimpson). 
Surface of carapax and of hands smooth, rostrum with three minute teeth.
