 specimens, attached behind the middle of the corresponding segment, and 

 exhibit a rather robust structure, the basal joint V>eing quite short, the pro- 

 podos very large and partly tubercular on the upper face, gradually tapering 

 distally, with the palm defined posteriorly by a strong projection, and exhi- 

 biting in front 2 triangular lobes separated by a narrow sinus. The dactylus 

 is extremely strong and curved, with a dentiform projection on the inner edge, 

 near the base. The length of the specimen is fulh' 23 mm.
