774 CRUSTACEA. 



Related to Girolance. The epistome anteriorly very broad and 

 transversely linear, and situated against the bases of the anterior an- 

 tennae. The anterior antennae contiguous at base. 



The general habit of the species here included is like that of the 

 33gaB and Cirolanae ; and the position of the bases of the antennae 

 is somewhat as in iEga. But the epistome is very short, being 

 transversely linear, and the second pair of antennae seem to come out 

 partly from under it. 



CORALLANA HIRTICAUDA. 



Corpus sat angustum, dimidio postico dorsi hirsutum usque ad abdominis 

 extremitatem. Caput parce transversum. Oculi grandes. Antennae 

 val.de ina3quo3 ; 2do3 longce segmentum thoracis btum attingentes, fla- 

 gellofermd lS-articulato ; \mo3 basi 2darum parce longiores. Abdo- 

 men §-articulatum, segmento ultimo triangulato, lateribus recto, extre- 

 mitate rotundato. Styli caudales abdominem non superantes, ramis 

 obtusis, externo multo angu-stiore, non longiore. Pedes breviter setulosi. 



Body moderately narrow, posterior half of back to extremity of abdo- 

 men hirsute. Head a little transverse. Eyes large. Antennae 

 very unequal; second pair long, reaching to fifth segment of 

 thorax; flagellum about eigh teen-jointed ; first pair not much 

 longer than base of second. Abdomen six-jointed, last segment 

 triangular; sides straight; extremity rounded. Caudal stylets not 

 extending beyond abdomen, branches obtuse, outer much the nar- 

 rower, not longer than the inner. Feet short setulose.

From the coral reefs of Tongatabu, where it was found in cavities 

 in dead coral.
