332 KEC0RDS OF THE AUSTRALIAN MUSEUM. 



Hab. — Haswell's original specimens were collected in Port 

 Jackson and are the only ones I have seen. Fulton and Grant 

 recorded the species from Port Phillip, "Western Port, and 

 Wilson Promontory, but the only specimens labelled M. 

 deflexifrons in Mr. Grant's collection, which was purchased by 

 the Trustees, are really JS T . tumida, so that those records possibly 

 refer to that species. 



Genus Zewa, 1 ^.. gen. nov. 



Carapace subpyriform, convex, either tuberculate or smooth, 

 without long spines. Rostrum formed of two diverging spines. 

 Eye-stalks long, partially retractile towards the sides of the 

 carapace. No true orbit : supraocular eave with a spine at its 

 hinder angle ; no true postocular spine, but a flattened one pro- 

 jects forwards from the hepatic region which is not cupped 

 and affords little shelter to the eye when retracted. Basal 

 antennal joint of moderate breadth, its antero-external angle a 

 little produced outwards; flagellum visible from above. Merus 

 of external maxillipeds a little broader than the ischium, ex- 

 panded at the antero-external angle, and bearing the palp at the 

 anterointernal angle. Chelipeds of adult male enlarged. The 

 first pair of ambulatory legs the longest. Penultimate joints 

 of all the legs cylindrical, not expanded distally. Abdomen of 

 the male composed of seven distinct segments. 



Type. — Z. banfieldi, sp. nov. Also includes Pseudomicij^ye 

 variaus, Miers. 



This genus is allied to Pseudomicippe, Heller, from which it 

 differs in the formation of the orbits, there being no large 

 antero-superior lobe as in that genus, while the hinder angle is 

 produced as a sharp spine. It differs from Naxia, Latreille 

 (Halimus, Auct. ) in having no large spines on the carapace and 

 in the penultimate joints of the legs being cylindrical instead of 

 dilated distally. 



/ i:\va banfieldi, sp. nov. 



(Plate x., figs. 5-6). 



Carapace elongate-triangular, the regions fairly well defined, 

 the surface uneven and rough with large tubercles. A very 



J3 " Zewa," a name for a crab in the Miriam language, Torres Strait.
