The first leg-bearing somite is very short and hardly visible from the exterior. The last three thoracic somites have each on the dorsal surface a pair of prominences beset with tubercles and spines. These prominences are largest on the last somite where they resemble the prominences of the abdominal somites. The pleural plates of the leg-bearing somites are slightly expanded and the whole surface is roughened with granules. The abdomen is little more than ,'4 of the length of the cephalothoracic region and the fifth somite is hardly longer than the preceding. The first four somites each bear on the dorsal surface a pair of stout sub-cylindrical processes, beset with tubercles, and terminating each in a stout spine (text-fig. i c). The height of the processes of the anterior somites, measured to
