CRUSTACEA DREDGED OFF PORT JACKSON IN 

 DEEP WATER. 



By F. E. Grant, F.L.S. 



(Plates x.-xi) 



The small collection of Crustacea forming the subject of this 

 paper was dredged in 250-300 fathoms about 28 miles east from 

 Port Jackson Heads, on an excursion in March of this year, 

 organised by Mr. W. F. Petterd. The object of the excursion 

 was mainly to obtain marine shells on the margin of the con- 

 tinental shelf, and the dredges used were designed rather for 

 this end than for obtaining such objects as crabs. Six species 

 only of Malacostraca were taken, of which four are Brachyura 

 and two Macrura. But as four of the species are new, and of 

 the remaining two only one has been recognised as belonging to 

 our fauna, the importance of the collection was greater than 

 would appear from its numbers. 



I desire to here express my thanks to Mr. Petterd for his 

 kindness in placing the specimens in my hands for study, and to 

 Messrs. C. Hedley, F.L.S., and T. Whitelegge, of the Australian 

 Museum, for much assistance rendered me in the task. 



The types of the species described will be lodged in the Aus- 

 tralian Museum.
