196 DISCOVERY REPORTS 



in a few instances in the present family, e.g. Stebbing, 1888, pi. lxxv. (Paramoera 

 australis), Chilton, 1912, p. 500 (Djerboa fnrcipes), and Monod, 1926, fig. 54 {Para- 

 moera austrina}). A few other examples could be added, as for instance Bate's descrip- 

 tion of the surface sculpture of Halirages huxleyanus. 



The figures given by Stebbing and Monod are very useful, because apart from other 

 characters they show conclusively that Stebbing's australis and Monod's austrina 

 cannot possibly be united with capensis. Whether Monod's austrina is the same as 

 austrina Bate must remain undecided until Bate's type, or material from the original 

 locality, can be examined. 



Although it necessitates the re-examination of much previous material, I think this 

 is a character which should be adopted, not only in the present family, but throughout 

 the Amphipoda and Crustacea generally. Every description of a species must be re- 

 garded as not fully complete which does not contain a mention of this "superficial" 

 feature. The present writer fully admits his own deficiencies in this respect. This feature 

 would have been mentioned throughout this report had not the present family, being 

 a difficult one, been left until last, and the importance of the character not fully realized 

 until the rest of the work had been completed. 



I would suggest that difficult genera like Orchomene, Orchomenella and Tryphosa 

 among the Lysianassidae be tested for this purpose. As regards technique, I need 

 scarcely say that the integument must be carefully cleaned of all foreign matter adhering 

 to it, and examined dry by reflected light; if not actually desiccated, there must at least 

 be no free water or moisture on the surface. 



Genus Bovallia, Pfr. 

 Pfeffer, 1888, p. 95. 

 Stebbing, 1906, p. 357. 

 Schellenberg, 1926, p. 354; 1929 a, p. 277. 



In Schellenberg's revision this genus is now monotypic, the other species formerly 

 included in it having been transferred as follows: walkeri (Stebb.) to Paramoera, 

 calliopioides , Schell., to Pontogeneia, and regis, Stebb., to Halirages.

Occurrence: 1. St. 174. South Shetlands. 1 $ 40 mm. 



2. St. 179. Palmer Archipelago. 1 945 mm., 3 ?? 20-24 mm., 2 juv. 10-11 mm. 



3. St. WS 56. South Georgia. 5 $$ 23-33 mm., 6 $$ 24-40 mm., kelp roots.

5. East Cumberland Bay, South Georgia. 1 ? 39 mm. 



Remarks. The integument is covered with scattered circular punctae anteriorly, 

 passing gradually into the elongate depressions which posteriorly are arranged in more 

 or less transverse rows, producing an imbricate appearance.
