830 REPORT—1896. 
antenne. In Platyonichus nasutus, which burrows in coarse shell gravel, a 
remarkable and characteristie prominence of the frontal area protects the anterior 
apertures from the accidental intrusion of foreign bodies. 
It thus appears that many of the specific and generic characteristics of 
Crustacea, which have been hitherto regarded as features of trivial significance are 
really of primary importance to their possessors under the particular conditions of 
their existence. : 
It is both remarkable and interesting that the same function in relation to the 
process of respiration should be discharged by organs and parts so dissimilar from 
one another as are the first antenne of Albunea, the second antennie of Corystes, 
the frontal area of Platyonichus nasutus, the five lateral spines of the carapace of 
Bathynectes, the nine lateral spines of Atelecyclus, the crests of the chelipeds of 
Calappa granulata, and the orbits of Matuta victor.
