MAERA HIRONDELLEI Chevreux.

The South African specimens agree so well with Chevreux' s species 

 that the few differences which are present cannot be regarded otherwise 

 than as local variations and also perhaps as due to age. Chevreux 

 expi-esses a doubt as to whether his $ $ were adult, but does not say 

 whether the $ $ were ovigerous. 



The 5th joint of 1st gnathopod indented on anterior margin just 

 before the acute apex. 



The hand of 2nd gnathopod is broader in proportion to its length 

 than in Chevreux's specimen, the two teeth at defining angle of palm 

 stronger. Chevi-eux in the enlarged figures of the 2nd gnathopod 

 (figs. Iy and I/) shows these 2 teeth, but in the text speaks of only 

 one. The insertions of the bundles of setae along the distal portion 

 of the inferior margin of hand rather deep, causing a distinctly serrate 

 appearance. 



The mandibular palp is of normal length (cf. Sars' figure of M. 

 othonis, Crust. Norw. vol. 1, pi. 182, fig. 1), the 3rd joint a little 

 shorter than 2nd.
