118 RECORDS OF THE S.A. MUSEUM 
South Wales: Lat. 28° 37’ S., long. 153° 42’ E. (K. Sheard, submarine light, 
Sept. 1938, 10.30 p.m. to 12.5 a.m.) ; off Wata Mooli, 70 metres, 9 a.m., and off 
Jibbon, 70 metres, and 45-50 metres (K. Sheard, July-Aug. 1943). 
Hab. South Australia, Tasmania and New South Wales. 
The above characters and those mentioned in the original description serve 
to separate tribulis from the North-Western Australian supersculpta Zimmer 
(1921, p. 7, fig. 8-11). Even in the very young of tribulis there is a slight trace 
of the elevation at the base of the eye-lobe, not shown in the figure of Zimmer’s 
much larger specimen. It is unfortunate that a complete individual of exsculpta 
Sars (1877, p. 20, pl. i, fig. 24-26) from Torres Strait, is not available. Sars’ 
species, described from the thorax only, was under 5 mm. long (estimated by 
Stebbing, 1913, p. 35) and while the sculpture is entirely different from that of 
tribulis, it is very close to supersculpta. 
Cycuaspis Bovis Hale. 
Cyclaspis bovis Hale, 1928, p. 82, fig. 1-2. 
A young example, 6-5 mm. in length, and with the last pair of peraeopods 
not developed, is referred to this species; it has the carapace relatively more 
massive and more strongly sculptured than in the almost adult female (c.f. fig. 
39, A and Hale, 1928, fig. 1). 

Fig. 39, Cyclaspis bovis, juvenile; lateral views of A, thorax and B, telsoniec somite and 
uropod; C, rami of uropod (A and B, X 12; C, X 66). 
The sides of the carapace are conspicuously excavate; the depression is 
bounded in front by the large and very much elevated antero-lateral tooth and 
dorso-laterally by a ridge extending forward from the posterior horns; the re- 
mainder of the edges of the depression bears large granules; these last are vaguely 
grouped at the sites of the two low elevations which are recorded for the types on 
the posterior part of the sides. 
The anterior transverse ridge is elevated and tubereulate medianly; the 
sculpture of the integument is squamose-reticulate. 
The uropods are relatively shorter than in the adult and the apex of the 
exopod (dilated in the adult) has a mucro; the endopod is barely longer than 
the exopod, is four-fifths as long as the peduncle (less than half as long in adult) 
and the inner margin has eight teeth. 
Loc. New South Wales; off Cape Three Points, 41-50 fath. (‘‘Thetis’’ Sta- 
tion 18, Feb. 1898). ; 
The species is large; the South Australian types, though immature, are 18
