Our Mount Kosciusko specimen may be defined thus — 



PilREATOlcus AUSTRALIS, sp. 710V., Plates xxiii. - xxvi. 



Body with surface generally uneven, wrinkled, and with irregular 

 depressions ; head and anterior portion of pleon smoother, a few 

 rather short setoi scattered over the surface and forming a short 

 thick fur on the dorsal portion of the last segments of the pleon. 

 Eyes small, round. Upper antennae reaching to the end of the 

 peduncle of the lower, peduncle apparently of tiiree joints, the 

 second much shorter and narrower than the first, third about as 

 long as the second but narrower, not distinguishable from the 

 fiagellum which is composed of four joints with a minute terminal 

 one and is somewhat swollen towards the end. Lower antennae 

 rather more than one-third the length of the body, peduncle of 

 five joints, first four short, subequal, fifth half as long again as the 

 fourth, flagellum longer than the peduncle. First pair of legs 

 having the propodos large and swollen and forming with the 

 dactylos a powerful subchelate liand. First five segments of pleon 

 with pleura produced inferiorly, rounded below, inferior and 

 posterior margins fringed with long setaj. Uropoda with peduncle 

 reaching about as far as the end of pleon, rami about as long as 

 peduncle, outer ramus shorter than the inner. 



Length, about half an inch (1 2-.'> nnn.), breadth, about one-tenth 

 inch (2-5 nnn.) Colour, (in spirit) legs and part of the body light 

 brown, the greater part of the body almost completely covered 

 with marbled markings of a darker brown. 



Jlab. Mount Kosciusko Plateau — at Piper's Creek, about .1,700 

 feet above sea-level. 



This species does not differ so much as might naturally have 

 been expected from the original species of the genus, Phreafoiciis 

 fypicus, a blind species found in wells in Canterbury, New Zea- 

 land. It is distinguisiied from that species however by the 

 possession of eyes, by the colour, the much shorter lower antennae 

 and by a few other points in the surface of the body, the set;v, Arc. 



I Iiave given this b'ief diagnosis becau.se T quite agree with the 

 remark that Brooks makes in his " Bcport on the ' Cliallenger ' 

 Stomatopoda" to the efl'ect that it is desirable that a brief diagnosis 

 of every new species should be given, although this should be 

 supplemented wherever possible by a much fuller description giving 

 the jjoints in which it resembles other species as well as those in 

 which it diflers from them. T ther-efore proceed now to a detailed 

 description of the various parts of the animal. 



Body, (Plate xxiii., fig. 1.) — The length of the body is usually 

 about half an inch, (12-5 mm.). It apjjears from the specimens 

 that I have examined, that the female is slightly smaller than the
