larger than the others : second pair of legs not quite twice the length of the carapace.

II. MAIADvE. 
In the family of the Maidce, many new and interesting forms, hitherto unknown, are 
here, for the first time, indicated, including two new genera and seventeen new species. In 
their habits, these Crustacea resemble the Inachidce, being very inert and apathetic, not 
using their chelie in self-defence, and covering themselves very frequently with foreign bodies. 
They appear to be diffused pretty equally over the globe, Chorims being found both in the 
east and west: Mithrax and Libinia seem to be confined to the New World; Micippe and 
Pericera are tropical genera, as are also Huenia and Mencethius ; while Maia, Ilyas, 
Arctopsis, and Pisa, are found in the countries of Europe.

Carapace with a row of tubercles varying in size in the middle line, a row of seven 
tubercles in each lateral region, internal to these, nearer the middle line, five other tubercles 
in a linear series ; sides with five spines, the hind one stronger and more prominent than the
