STUDIES IN AUSTRALIAN CRUSTACEA-McCULLOCH. 57 



Ambulatory legs deeply pitted all over; all the joints with 

 distinct crests on the front and hinder margins. Dactyli expanded 

 behind with a curved ridge on either side. 



Colour, quite white all over. Length, 8-3 mm.; breadth, 10 - 8 



mm. 



I have compared this specimen with the type in the Macleay 

 Museum, which is about the same size, and there can, therefore, 

 be no doubt of its correct identification. The adult form is 

 unknown. 



Coogee Bay, near Sydney, after a storm. 



Gabrielia carinata, Baker. 



Cycloxanthus 1 carinatus, Baker, Trans. Roy. Soc. S. Au.str., 

 xxxi., 1907, p. 173, pi. xxiii., f. 1. 



Through the kindness of Mr. Baker, I have received a fine 

 specimen of this species from Port Lincoln, South Australia. I 

 agree with him that it is easily distinguished from the other two 

 species by its nearly horizontal front, and the thin cristate 

 antero-lateral margins. 



In these two characters it approaches Cyclovanthops, and shows 

 the close relationship of Gabrielia to that genus, but the arched 

 front lacking a median notch is quite sufficient to distinguish the 

 two. I may add here that it is the only one of the three species 

 which has any trace of the notch near the inner orbital angles 

 which is so characteristic of Cycloxanthops. 



EURYCARCINUS MACDLATUS, A. M. Edw. 



Eurycarcinus maculatus (A. M. Edw.), De Man, Journ. Linn. 

 Soc, Zool., xxii., 1888, p. 44, pi. ii., figs. 2-3. Ortmann, 

 Zool. Jahrb., vii., 1894, p. 435. 



Actumnus nudits, Grant & McCulloch, Proc. Linn. Soc. 

 N. S. Wales, xxxi., 1906, p. 17 {nee. A. M. Edw.). 



Owing to the numbers at the foot of De Man's plate being- 

 transposed, we have wrongly recorded this species from Port 

 Curtis as Actumnus nudus. Specimens from Moreton Bay agree 

 perfectly with his figure, and it has also been recorded by 

 Ortmann from East Australia. Actumnus nudus does not, so 

 far as I am aware, occur in Australia.
