292 ATJSTBALIAN MALACOSTBACA. 



ridged ; anterolateral angle acute, postero-lateral rather blunt. 

 Following thoracic segments more or less distinctly granular. 

 First abdominal segment distinctly granular, produced backwards 

 towards the middle dorsal line, with a short thick process on 

 either side. Terminal segment with two large tubercles near the 

 middle, and a transverse line of three more near the distal 

 border. Terminal notch wide, the median process prominent, 

 broad, rounded at the extremity. Basal joints of the inner 

 antennae oblong, granular, separated by an acute frontal process ; 

 second joint small ; flagellum about equalling the peduncle in 

 ' length. Outer antennae longer than the inner. Inner ramus of 

 the uropoda longer than the outer, obliquely truncate, each 

 terminating in a small acute spine. Length \ in. 

 Griffiths' Point, Victoria. 



This species bears some resemblance to O. Latreillii, of Leach, 

 but the blunt form of the terminal lobe, as well as the shape of 

 the uropoda, etc., sufficiently distinguishes it. 



504. Oymodooea coronata. A.M. 

 Gymodocea coronata, Haswell, 1. c, Vol. vi., p. 10. 



Head and thorax as in 0. bidentata, but with the hairs shorter. 

 Abdomen rather depressed, covered with short hairs, ornamented 

 with six small pointed tubercles arranged in a circle — two near 

 the posterior border of the first segment, the rest on the second. 

 Terminal notch very wide — nearly a third of the breadth of the 

 abdomen ; mesial lobe very large, dilated at its base, but narrow- 

 ing towards its apex which is blunt. Mobile ramus of uropoda 

 much shorter than the immobile *amus, sub-falciform, truncate. 

 Inner ramus very long, extending far beyond the extremity of 

 the abdomen, long-ovate, apex rounded. Length i in. 



Griffiths' Point, Victoria. 



An ally of G. aculeata, mihi, but distinguished, besides other 

 points, by the greater relative shortness of the mesial Jobe and 

 the smallness of the mobile ramus of the uropoda.

 Gymodocea tuberculata, Haswell, 1. c., p. 10, pi. iii., fig. 8. 

 Greatest breadth exactly half the total length. Head and first 



segment of body smooth — the latter equalling in length the three
