2io DISCOVERY REPORTS 



Occurrence: St. MS 82. Saldanha Bay, South Africa. 20 ?? 5-9 mm., the larger ovig. 



Remarks. Integument nitidulous, with numerous pits which in the posterior seg- 

 ments sometimes tend to become elongate so as to produce the appearance of short 

 lines. This is especially noticeable in specimens from 

 the more easterly localities (Port Elizabeth, East 

 London and Natal), in which also the pits tend to 

 be slightly stronger and closer together. Post- 

 antennal angle of head rounded-quadrate. 



Schellenberg (1925) has shown that the inclusion 

 of magellanica, Stebb. (= Atyloella m.) in the —j- 



synonymy which I gave in 19 16 was wrong. I agree.

On the other hand, I still maintain that austnna, B A w r 



a. Head. b. Pleon segment 3. 



excluded by me in 1916, is rightly excluded. 



I see no possibility of including a species with a telson like that in Bate's figure (pi. 

 xxvi, fig. 4) with capensis. The same applies to australis, Miers. The normal telson of the 

 adult should be used as a criterion, and in capensis it is comparatively short and broad, 

 with multidentate apices. 



Moreover, the integument of austrina has yet to be recorded. In australis Stebbing 

 describes it as scabrous on the posterior segments. In the two to three hundred speci- 

 mens from various South African localities which I have examined, I have not found a 

 trace of scabrous ornamentation. 



There would appear to be no difficulty in finding differences (integument, shape of 

 head, pleon segment 3, telson, etc.) if one looks for them, instead of endeavouring to 

 find points of agreement with a view to recording one "widely distributed species." 



Distribution. South Africa, west coast as far north as Swakopmund, south coast as 

 far east as Port Shepstone in Natal; St Helena (Schellenberg, 1926). 



Paramoera bidentata, n.sp. (Figs. 118 m, 129). 



Occurrence: South Africa, Kalk Bay (False Bay). 1 ? 15 mm. (S.A.M. Reg. no. 1294). 



Description. Integument very minutely shagreened, without pits. Rostral point 

 small, acute. Antero-lateral margin of head somewhat angular, post-antennal angle 

 acutely produced. Eyes reniform, nearly meeting on top of head. Side-plates 1-4 

 moderate, lower margins not setose or serrate. Pleon segments 1 and 2 with the pos- 

 terior margin produced in a medio-dorsal subacute triangular tooth, which is not carinal 

 but lies flat; postero-inferior angle of segment 1 quadrate, of 2 quadrate with a very 

 small point, the margin above slightly sinuate, of 3 quadrate with a small point, the 

 margin above rather convex but not serrate ; segment 4 with an unusually well-marked 

 dorsal transverse depression. Telson twice as long as broad; cleft two-thirds its length, 

 lateral margins nearly straight, apices acute with two unequal spiniferous notches, the 

 outer being the larger and bearing the larger spine, two submarginal unequal spines 

 near base.
