serrated. Antero-lateral margin with three flattened teeth, (the 
external angle of the orbit excluded), the posterior triangular, anterior 
rounded and lamellar. Anterior legs strong, often unequal, finely 
granulated, especially on upper edges, hand compressed, swollen in 
centre, curved, fingers moderate, curved, rounded, mobile one with a 
longitudinal depression on its exterior edge, wrist finely granulated, 
a strong spine on its superior external angle. Orbits oval, superior 
border finely tuberculated, with two short fissures, a deep narrow 
external fissure, orbital hiatus broad, inferior border two lobed, the 
inner lobe produced, tooth-like. Colour yellowish brown. Length 
2 in.; breadth 1d in. (K.). 
New Zealand (Coll. Brit. Mus.); Australia, Port Philp (Coll. 
Brit. Mus.). 
Pilumnopeus crassimanus of A, M. Edwards, is possibly identical 
with this species, but it is too shortly described for me to be certain 
on this point.

Ozius, M. Edw. Hist. Nat. Crust. i, p. 404, (1834). 
Carapace transverse, flattened. Antero-lateral margin usually dentate 
and shorter than the postero-lateral. Palate witha strong ridge on either 
side, defining the margin of the efferent channel. External antenne 
with the basal joint completely reaching the front, the flagellum 
entering the internal orbital hiatus. Anterior legs with the fingers not 
spoon-excavate at the extremity ; ambulatory legs of normal shape, 
not cristate above.

Carapace not very wide, nearly flat above, and slightly tuberculated 
in front. Front very wide, nearly straight, slightly simuous, without 
a transverse groove in front; orbits without distinct fissures ; latero- 
anterior margins short, divided into four or five wide obtuse lobes. 
Pterygostomian regions granulous, and third joint of the external 
maxillipeds with the anterior margins notched. Basal joint of the 
external antenne very oblique, flagellum rudimentary, the internal
