Direct comparison, however, with Japanese examples in the 

 Australian Museum, removes any doubt as to specific identity. 

 Ours are small specimens, and the rugosities noticed become less 

 distinct in larger individuals. 



Family GALATHEID^. 

 Genu's Galathea Fabricius. 



The collection having provided us with material from the 

 Queensland coast near to the localities in which some of Haswell's 

 types were taken, and that author's specimens being available to 

 us for comparison, we have taken this opportunity of revising the 

 whole of the recorded Australian species of the genus. 



It appears to us that, after elimination of the synonyms 

 discussed below, the authenticated species recorded from the 

 East Coast of Australia may be set down as six, as shown in the 

 following key : — 



A. Rostrum with three lateral teeth. 



B. Striations of carapace continuous on both anterior 

 and posterior half. 

 C. Rostrum broad, two spines on inner border of merus 



of maxillipeds; ringers moderate , G. australiensis. 



CC. Rostrum slender, three spines on inner border of 



merus of maxillipeds; fingers long. . . G. ivhiteleggii. 



BB. Striations on anterior half of carapace not con- 

 tinuous. 

 D. Chelipeds robust, carpus short, fingers half length 



of hand G. magnified. 



DD. Chelipeds slender, carpus long, fingers more 



than half length of hand G. aculeata. 



AA. Rostrum with other than three lateral teeth. 



F. Rostrum with one lateral tooth G. pusilla. 



FF. Rostrum with seven small lateral teeth G. elegans. 



The species of this genus are characteristically variable, the 

 variations no doubt being determined by age, environment and 

 other circumstances; and the brief diagnosis of each which 

 we here give must be taken only as characterising in toto those 

 specimens which are actually before us and of which figures are 

 given.
