258 Annals of the South African Museum. 
In Proce. U.S. Nat. Mus. vol. 43 [1913], p. 376, Pearse gives a figure 
of G. compta Smith (?) and in the text says the specimens differ from 
Holmes’ figures (Le. supra): the chief difference apparently being 
that the Ist gnathopod is larger than the 2nd. If this is so, the 
specimens would seem to belong more properly to Paragrubia Chevreux 
1901. I believe, however, that Pearse has accidentally made a shp 
and transposed the two limbs, since the so-called “gn, J” and “ gn, gd” 
in his figures correspond exactly in relative size as well asin the shapes 
of the component joints with the second and first gnathopods respec 
tively of an ordinary species of Grubia; ct. for example Chevreux’s 
figure of G. hirsuta (1.c. 1900). 
GRUBIA AUSTRALIS, 0. sp. 
Body robust, dorsally rounded, not compressed. Eyes subrotund, 
faimt in colour, situate in the antero-lateral angles of head. Side- 
plate 1 produced forwards but not beyond the vertical from the 
posterior margin of eye, 1-4 fringed, but not densely, on inferior 
margin with long simple setae, anterior lobe of 5 larger and deeper 
than any of the preceding. Postero-inferior angle of 5rd pleon seg- 
ment bluntly quadrate. : 
Telson broader than long, distal margin convex between the sub- 
acute lateral angles, a group of 2-3 setae in the middle of the lateral 
margin, another group of ca. 6 longer setae near the lateral angles. 
First antenna longer than 2nd, reaching to end of peraeon (+ length 
of body), Ist and 2nd joints subequal, 3rd 4 2nd, flagellum longer than 
peduncle, accessory flagellum very small, 1-jointed, scarcely half length 
of Ist flagellar jot, with 2 apical setae. 
Second antenna reaching to about 5th peraeon segment, ultimate 
and penultimate joints subequal, flagellum a little longer than 
peduncle. 
Neither antenna strongly setose. 
Upper lip broader than long, apical margin convex and setose. 
Lower lip, outer lobes shallowly bifid. 
Mandibles, cutting-edge 8-dentate, secondary cutting-edge 7-dentate, 
spine-row with 6 spines, 2nd and 3rd joints of palp subequal in 
length. 
First maxilla, inner plate with 6 faintly plumose setae, outer plate 
with 10 spines, palp with 9 spine-setae. 
Second maxilla, inner plate only half the width of outer. 
Maxilliped, outer plate with ca. 17 simple, not serrate, spine-teeth 
on inner margin.
